THE EARTH- OUR PLANET
5/17/2016
SUNThe Sun is the star at the center of the Solar System and is by far the most important source of energy for life on Earth.
EARTH IS THE THIRD PLANET FROM THE SUN
Earth is the third planet from the Sun and is the largest of the terrestrial planets. The Earth is the only planet in our solar system not to be named after a Greek or Roman deity. The Earth was formed approximately 4.54 billion years ago and is the only known planet to support life.

PLANET NINEOn Jan. 20, 2016, scientists announced the discovery of what could be a giant planet in the Kuiper Belt at the outer edge of our solar system. Nicknamed "Planet Nine," the world is a behemoth - about 10 times the mass of the Earth. It would take the planet between 10,000 and 20,000 years to orbit the sun.

Specially about moons
• Moons in our Solar System • As of October 2008, there are 181 known natural moons orbiting planets in
our Solar System. 173 moons orbit the "full-size" planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), while 8 moons orbit the smaller "dwarf planets" (Ceres, Pluto, Haumea, Makemake, and Eris).
Now lets study about asteroids
• Facts about asteroids. Asteroids are small, rocky objects that orbit the Sun. The first asteroid was Ceres, discovered by Giuseppe Piazzi in 1801. There are currently over 600,000 known asteroids in our solar system.
Now comes Meteoroids
• A meteoroid is a small rocky or metallic body travelling through outer space. Meteoroids are significantly smaller than asteroids, and range in size from small grains to 1 meter-wide objects.
Now meteorite
• A meteorite is a fragment of rock or iron from outer space, usually a meteoroid or asteroid, which survives passage through the atmosphere as a meteor to impact the surface of the Earth. Meteorites are believed to originate in the asteroid belt between the planets of Mars and Jupiter.
Comets
• A comet is a very small solar system body made mostly of ices mixed with smaller amounts of dust and rock. Most comets are no larger than a few kilometers across. The main body of the comet is called the nucleus, and it can contain water, methane, nitrogen and other ices.
KUIPER BELT
• a region of the solar system beyond the orbit of Neptune, believed to contain many comets, asteroids, and other small bodies made largely of ice.
This includes things such as planets, comets, asteroids, meteoroids and moons. The Solar System formed around 4.6 billion years ago. There are eight planets in the Solar System. The four inner planets are Mercury, Venus, Earth and Mars while the four outer planets are Jupiter, Saturn, Uranus and Neptune.
