This document provides information about objects in the Solar System. It begins by describing the Sun and planets such as Earth, Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune. It then discusses other objects like moons, asteroids, meteoroids, meteorites and comets. It notes there are over 600,000 known asteroids and 181 known natural moons orbiting planets in the Solar System. The Kuiper Belt, a region beyond Neptune's orbit containing small icy bodies, is also mentioned. The document aims to educate about the formation and composition of our Solar System around 4.6 billion years ago.

2. SUN
The 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.

3. EARTH IS THE THIRD PLANET FROM
THE SUN
Earth is the third planet from the Sun and is the

14. PLANET NINE
On 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.

15. This is our galaxy

17. 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).

18. 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.

19. 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.

20. 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.

21. 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.

22. 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.

23. 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.
