WHAT IS SOLAR SYSTEM ?

Solar system is a system in the universe made up of the sun as its centre and other astronomical objects, like planets, asteroids, satellites, comets, and meteorites orbit the center or sun in their each orbits.

THE SOLAR SYSTEMThe Formation of the solar system :

1. Sun

2. Planet

3. Asteroid

4. Satellite5. Meteoroite6. Comet

1. The Sun

• The sun is the biggest, barightest, and hottest object in the solar system.

• The sun is an ordinary star.

• The sun is made of about 70% hydrogen and 28% helium.

The Structure of Sun

1. Core

2. Radiative Zone

3. Convective Zone

4. Photosphere

5. Cromosphere

6. Corona

7. Sunspot

8. Granules

9. Prominance

2. Planets• Planets are celestial body that can not emit light theirselves.

Ex : Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

Mercury

• Mercury is solid and is covered with craters.

• Mercury has almost no atmosphere.

• Mercury is the eighth largest planet.

Venus

• Venus is the sixth largest planet. It’s about three-fourths the size of earth.

• The surface is rocky and very hot. The atmosphere completely hides the surface and traps the heat.

Earth

• Earth is the fifth largest planet and the third from the sun.

• Liquid covers 71 percent of the Earth’s surface.• The Earth has one moon.

Moon

Mars

• Mars is the fourth planet from the sun.

• Mars has a thin atmosphere that contains mostly carbon dioxide.

• Mars has two small moons.

Moons of Mars

Phobos

Deimos

Jupiter

Jupiter’s Red Spot

• The Great Red Spot, a huge storm of swirling gas that has lasted for hundreds of years.

• Jupiter does not have a solid surface. The planet is a ball of liquid surrounded by gas.

Moons of Jupiter

Jupiter has four large Galilean moons, twelve smaller named moons and twenty-three more recently discovered but not named moons.

We’ll take a look at the four large Galilean moons which were first observed by Galileo in 1610.

Io

– Io is the fifth moon of Jupiter. It’s the third largest of Jupiter’s moons.

– Io has hundreds of volcanic calderas. Some of the volcanoes are active.

Europa

• Europa is the sixth of Jupiter’s moons and is the fourth largest.

• It is slightly smaller than the Earth’s moon.

• The surface strongly resembles images of sea ice on Earth. There may be a liquid water sea under the crust.

• Europa is one of the five known moons in the solar system to have an atmosphere.

Ganymede

• Ganymede is the seventh and largest of Jupiter’s known satellites.

• Ganymede has extensive cratering and an icy crust.

Callisto

• Callisto is the eighth of Jupiter’s known satellites and the second largest.

• Callisto has the oldest, most cratered surface of any body yet observed in the solar system.

Saturn

• Saturn is the second largest planet and the sixth from the sun.

• Saturn is made of materials that are lighter than water. If you could fit Saturn in a lake, it would float!

Rings of Saturn

• Saturn’s rings are not solid; they are composed of small countless particles.

• The rings are very thin. Though they’re 250,000km or more in diameter, they’re less than one kilometer thick.

Uranus

• Uranus is the third largest planet and the seventh from the sun.

• Uranus is one of the giant gas planets.

• Uranus is blue-green because of the methane in its atmosphere.

Neptune

• Neptune is the fourth largest planet and the eight from the sun.

• Because of the orbits, from 1979 to 1999, Neptune was the ninth planet.

• Like Uranus, the methane gives Neptune its color.

a. Earth as a barrier planet grouped into two, namely inferior planet and superior planet.

• Inferior Planets are planets whose orbits are in Earth‘s orbit.

• Which includes the inferior planets are Mercury and Venus

• The Grouping of Planets

• Superior Planets are planets whose orbits are outside Earth’s orbit .

• Which includes the superior planets are Mars, Jupiter , Saturn, Uranus and Neptune

Asteroid

b. Asteroid as a barrier planet group into two, Inner planet and Outer planet

• Inner planets are the planets in Asteroid’s orbit

• Which includes in inner planet: Mercury, Venus, Earth and Mars.

• Outer planets are the planets outside Asteroid’s orbit,

• Which includes in outer planet: Jupiter, Saturn, Uranus and Neptune.

Planet Terestrial

Planet Jovian

c. Based on the sizes and the compositions, Planets group into Terrestrial and Jovian

• Terrestrial Planets are the planets which size nd composition almost like Earth,

• Which includes in Terresterial Planet: Mercury, Venus, Earth and Mars.

• Jovian planets are the planets which a great size and the composition almost same to Jupiter.

• Which includes in Jovian Planet: Jupiter, Saturn, Uranus and Neptune.
