The Solar System[c] is the gravitationally bound system of the Sun and the objects that orbit it. It formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority (99.86%) of the system's mass is in the Sun, with most of the remaining mass contained in the planet Jupiter. The four inner system planets—Mercury, Venus, Earth and Mars—are terrestrial planets, being composed primarily of rock and metal. The four giant planets of the outer system are substantially larger and more massive than the terrestrials. The two largest, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium; the next two, Uranus and Neptune, are ice giants, being composed mostly of volatile substances with relatively high melting points compared with hydrogen and helium, such as water, ammonia, and methane. All eight planets have nearly circular orbits that lie near the plane of Earth's orbit, called the ecliptic.

The Solar System

3. • Mercury
• Mercury is the smallest planet. It is also the
nearest to sun. Mercury has no moon.

4. • Venus
Venus is known as twin planet of the earth, as it is
almost of same .size as the earth. It is the brightest
and the hottest among all plants. It is also known as
morning star or evening star, as it is seen either just
before the sunrise or just after the sunset. Venus
have no moons

5. Earth:
The earth is the third planet from the sun and the
only planet that support life. Two-thirds of the earth's
surface are covered with water. The earth is also
known as the blue planet. It has only one moon.

6. Mars
Mars is known as red planet
an is the fourth planet from
sun. It has two moons

7. Jupiter
Jupiter is the largest of all planets. It has faint rings
around it. It has many moons.

8. Saturn
Saturn is known as the ringed planet and it as large as
Jupiter. There are many bright rings around Saturn
Making it the loveliest of all planets. It also has many
moons.

9. Neptune
Neptune is the farthest planet
from the sun. It has faint rings
and moons around it.

10. Uranus
Uranus is a very unique planet. It is the seventh
planet from the sun. It is the only planet which rolls
on its sides, on its axis. The other planets spin
upright. Uranus is also encircled by many thin rings
and moons.
