If you look into the sky from the earth on a clear night, you may see many bright dots. Some are brighter than the others. Some are big, others are small, sometimes we asked ourselves where these things came from are? What will happen if they do not exist?

Planetisimal Theory states that the sun, a big star, collided with the small star. The impact of the collision causes the ejection of particles into space. These particles later became the members of the Solar System. The planets form out of dust grains that collide and stick to form larger and larger bodies.

When the bodies reach sizes of approximately one kilometer, then they can attract each other directly through their mutual gravity, aiding further growth into moon-sized protoplanets enormously.

When the bodies reach sizes of approximately one kilometer, then they can attract each other directly through their mutual gravity, aiding further growth into moon-sized protoplanets enormously.

This is how planetisimals are often defined. Bodies that are smaller than planetisimals must rely on Brownian motion or turbulent motions in the gas to cause the collisions that can lead to sticking. Alternatively, planetisimals can form in a very dense layer of dust grains that undergoes a collective gravitational instability in the mid-plane of a protoplanetary disk.

Many planetisimals may eventually break apart during violent collisions, but a few of the largest planetisimals can survive such encounters and continue to grow into protoplanets and later planets. It is generally believed that by about 3.8 billion years ago, after a period known as the Late Heavy Bombardment, most of the planetisimals within the solar system had either been ejected from the solar system entirely, into distant eccentric orbits such as the Oort cloud, or had collided with larger objects due to the regular gravitational nudges from the Jovian planets (particularly Jupiter and Neptune). A few planetisimals may have been captured as moons of the Jovian planets.

According to this theory, rings of hot gases were developed and were shed off. As the gases cooled and condensed, they broke off into fragments to form the members of the Solar System.It was first proposed in 1973 by Emanuel Swedenborg. Originally applied only to our own Solar System, this method of planetary system formation is now thought to be work through out the Universe. Star formation is a complex process, which always produces a gaseous protoplanetary disk around the young star. This may give birth to planets in certain circumstances, which are not well-known.

Sunlight has approximately a black-body spectrum that indicates its temperature is about 6 000 K, interspersed with atomic absorption lines from the tenuous layers above the photosphere.

They can be seen with telescopes across the electromagnetic spectrum, from the visible light to gamma rays. As we look down into the atmosphere at the surface of the Sun the view becomes more and more opaque. The point where it appears to become completely opaque is called the photosphere. Thus, the photosphere may be thought of as the imaginary surface from which the solar light that we see appears to be emitted. The diameter quoted for the Sun usually refers to the diameter of the photosphere. Radiation emitted from the photosphere accounts for most of the solar energy flux at the Earth.

Chromosphere is a thin layer present above the visible surface on photosphere, which is about 2000 km. thick specifically dominated by a spectrum of emission and absorption lines. It is called the chromospheres because t comes from the Greek root “chromos” meaning “color”. Another term for chromospheres is the color sphere, for this reason, the color sphere is visible as a colored flash at the beginning and the end of total eclipse of the sun.

The term “chromospheres” was first applied to the red ring and large prominences seen at the edge of the eclipsed Sun with the unaided eye. Emission in the Balmer-alpha line of hydrogen at 653-nanometer wavelength accounts for the red color. The solar chromospheres extends from roughly 500 km (300 mi) above the photosphere to where hydrogen becomes fully ionized and the gas temperature rises rapidly to more than 106 K (1.8 × 106 °F) in the corona. Stars with effective temperatures less than about 8000 K (14,000°F; the Sun is 5770 K or 9930°F) show the same emission lines as the solar chromospheres and are thus thought to have analogous regions.

The Laws of electromagnetism prohibit the intersection of two magnetic field lines, every time magnetic field lines come cross to crossing, they are “rearranged” and this magnetic reconnection continuously heats the solar corona. As a direct consequence of this theory, the heating process should occur much closer to the surface of the sun than previously thought, but no one really knows how close.

The corona can be seen during solar eclipses, when the main radiation from the sun’s surface is blocked by the passage of the moon. One of the most puzzling features of the sun is what has been dubbed “the solar corona problem”. There is a region around the sun, existing more than one million kilometers from its surface, where the temperature can reach two million degrees. This region, called the Solar Corona, is where the solar wind originates.

The Core is the innermost layer of the sun and it is a source for all the sun’s energy. The material in the core is firmly attached and has very high temperature, which is about 15 million degrees Kelvin. In the core, the intense heat destroys the internal structure of an atom and therefore all atoms are broken down into their constituent parts. An atom is composed of protons, electrons and neutrons.

The charge neutral material of protons and electrons that makes up the core called plasma. Thermonuclear reactions takes place inside the core, thus hydrogen atoms are combined with each other to make the helium atoms and produces energy which keeps the sun in a state of equilibrium. Thus, this thermonuclear reaction is called nuclear fusion.

The Central Core decays, electromagnetic waves on the surfaces of the core include normal elementary particles that create an envelope of material that surrounds the core. The major source of the sun’s energy is the decaying central core. In essence, almost every particle of material that exists in the envelope, the sun-excepting particles pulled in by gravity is created, that is induced by the electromagnetic field on the surface of the core of the sun.

Mercury’s axis is the straightest of the planets, with the least “tilt”. This is the reason why Mercury has only one season.

Mercury is not an easy planet to find in the sky because it stays close to the sun. You can sometimes see it in the east just before sunrise or in the west just after the sunset. It looks like a pinkish star. Even through a telescope, you can make out few details of the planet’s surface. Mercury is covered with craters and looks much like the moon. The major difference between the two bodies is that Mercury has no large flat plains or seas, like the moon.

It is believed that Mercury resembles very much the Moon (its diameter is almost as twice as the diameter of Earth's only satellite). Its surface carries the signature of heavy asteroid and meteorite bombardment that took place since its early ages, recognizable by the huge amount of craters of all sizes that dots the surface. Mercury basically doesn't have any atmosphere, so the 'sky' surrounding it is always black.

Venus is the easiest to recognize. On many evenings at sunset we see it shining brightly in the western sky as the evening star. At another times we see it shining in the eastern sky at dawn as the morning star. Venus shines brighter than any other planet for two reasons.

First, it is the planet that comes closest to the Earth, sometimes within 26 million miles. Second, it is permanently covered with thick clouds, which reflect sunlight brilliantly. In size, Venus is near twin of the Earth, being only slightly smaller. It also has atmosphere. It is relatively close to us in the Solar System. We might think, therefore, that Venus would be a similar planet to the Earth but nothing could be farther from the truth.

Earthquake, floods and erosion are always changing the surface of the Earth. Earth spins on its axis like a top, once a day, at a speed of about 10,000 miles an hour at the equator. Everything around us on Earth –building, trees and animals—spins at the same speed so we don’t notice that Earth is moving. As the Earth spins, the sunlight spins in different parts of our planet at different times. This creates day and night.

Mars can be easily seen from Earth without telescope at a brightness that is only surpassed by the planet Venus, the moon and the sun. Mars has long been considered the most realistic location for life in our solar system, aside from Earth. Many believe that intelligent life may have once existed on the planet. Scientific exploration of Mars has not produced any evidence of life on planet. It is believed that the harsh surface environment and extreme solar radiation that saturates the surface of planet is not capable in sustaining any kind of life.

Jupiter's four large moons Io, Europa, Ganymede and Callisto (now known as the Galilean moons) and recorded their motions back and forth around Jupiter. This was the first discovery of a center of motion not apparently centered on the Earth. Jupiter and the other gas planets have high velocity winds which are confined in wide bands of latitude. The winds blow in opposite directions in adjacent bands. Slight chemical and temperature differences between these bands are responsible for the colored bands that dominate the planet's appearance. The light colored bands are called zones; the dark ones belt.

Saturn is the second largest planet. Its rings are made of thousands of ringlets of dust, water, ice and very small particles. It is unusual in the sense that they are composed of materials, which are similar to those of the sun. They actually emit more energy than the amount they receive from the sun. They are estimated to contain more than 90% of the mass of the Solar System outside the sun. Saturn is made up mostly of hydrogen, a light gas.

Saturn is the most distant planet we can see in the naked eye, but we need a telescope to see its rings. Large telescopes reveal that its disk is crossed with parallel bands,, but they are much fainter than those on Jupiter. Saturn, then, is a smaller and paler version of Jupiter and is thought to be much like Jupiter in make up. It too has a strong magnetic field and radiation belts.

The planet Uranus is the seventh from the sun. Its 51,117km diameter classifies it as the third largest planet in the solar system. By mass, Uranus is the fourth largest. Despite not being certain how the planet Uranus inherited its 98° axial tilt; we are able to study the effects of this uneven heating. Hypotheses suggest this unique aspect is due to a major collision during formation. John Flamsteed first recorded the planet in 1690, but believed it was a star. Almost 100 years later in 1781, Sir William Hershel made the formal discovery.

Although there are no current plans to physically explore Uranus, the planet was visited in 1986 by the NASA spacecraft, Voyager 2. The surface composed of rock and ice is surrounded by an atmosphere of hydrogen, helium and methane. Uranus’ average temperature is -218°C, or -360° F. So far thirteen rings surrounding Uranus have been found.

Making the Neptune the most distant planet from the Sun for the few years. Neptune composition is probably similar to Uranus various “ ices ” and rock with about 15 % hydrogen and a little helium.

Because Neptune is so far away, little was known about it until Voyager 2 sped by it in 1989. The planet is a deep blue color and shows interesting features, such as dark spots and white wisps. Neptune has also a set of faint rings around of it. This means that all four giant planets have ring system, but only Saturn’s rings can be seen from Earth.

On 1994 the dark spot has disappeared but a few months later the new dark spot discovered on the Northern Hemisphere. This indicates that Neptune’s atmosphere changes rapidly.

Asteroids are composed of rocks and metals. Ceres is the biggest asteroid with a diameter of about 800 kilometers. Then very little is known about these bodies by astronomers with diameter from 16 to 160 kilometers. Asteroids are rocky and metallic objects that orbit the sun but are too small to be considered planets. They are known as minor planets. They are material left over from the formation of the solar system.

One theory suggests that they remains of a planet that was destroyed in the massive collision long ago. Astronomers have studied a number of asteroids through Earth-based observations. Several notable asteroids are Tautahs, Castalia, Geographo and Vesta.

A comet develops tail as it approaches the sun. The intense heat exerts a pressure on the particles in the head. The tail always points away from the sun. Most comets are estimated to require about 10,000 years to complete one circuit of the sun. A great majority of comets we observe will not be visible again from the Earth for thousands of years. There are many historical records and works of art which record the appearance of comets and link them with terrible events such as wars and plagues. Now we know that comets are lumps of ice and dust periodically come into the center of the solar system from somewhere in its outer reaches and that some comets make repeated trips. When comets get close enough to the sun , heat makes them start to evaporate.

Meteors are rocks that fly into the atmosphere of the Earth. These rocks are made of iron and nickel. These objects in space are also called shooting stars. Meteors are believed to have come from tails of comets or from small fragments of asteroids Meteors travel in space of about 40 kilometers per second. This friction with the air causes meteors to glow brilliantly.

However, the effects are not seen below an altitude of 15 kilometers. When there are numerous meteors, a meteor shower occurs. Upon reaching the Earth’s atmosphere, most meteors vaporize. Those that do not burn completely and fall on Earth are called Meteorites.

Most of the meteors seen during one of the annual showers arise from fluffy particles not much larger than sand grains as the particles enters Earth atmosphere, it collides with the gas atoms and molecules. The particles becomes wrapped in a glowing sheath of heated air and vaporized material boiled off its own surface. Meteors become visible at altitudes between 50-75 miles with faster particles typically shining at greater heights.

As the star collapses in size, it continues to cool. It then becomes faint until it cannot be seen anymore. A collapsing star may suddenly flare up and become thousands of times bigger. It is called a nova. It is the last stage and is about to die. After such brilliance, the star collapses and finally dies.

Stars do not really twinkle. They appear to twinkle because we see them through layers of air surrounding Earth as their light passes through the air layers, the light’s speed changes as it moves from one layer to another.

Stars evolve from hydrogen gas found in interstellar medium called Nebulae. The mass of gas contract within a nebula. The hot ball begins to glow and it is the birth of a new star.

During the early stage of the star’s evolution, the temperature rises due to nebular reaction within the stars. The young star then becomes a mature white star, like the sun. Eventually a star will undergo a new series of internal reactions that will cause it to expand. When most of the nuclear fuel is consumed, the star will pulsate and finally contract to a cooling white dwarf.
