Solar system is made up of one star .
A handful of planets more than a hundred moons millions of rocky
asteroids and billions of comets.
All these bodies revolve
around the Sun because of the gravity of the Sun .
Gravity of the Sun is a force that pulls the objects toward the
center of the Sun .
The Sun is the only star in our solar system.
It is a huge ball of fire
shooting light and heat in all directions.
No living thing can
survive without the Sun.
All the planets and the
moons use sun rays for their light .
There are eight planets in our solar system.
They are Mercury ,Venus,Earth ,Mars ,Jupiter ,Saturn, Uranus and
Neptune .
Venus is the hottest planet of the solar system.
Earth is the planet where we live.
It is the third planet
from the Sun after Mercury and Venus
Earth is the fifth biggest
planet of the solar system but all the planets are tiny in comparison to the
Sun.
It takes 365 days to
revolve around the Sun earth looks blue
from space because it is mainly covered by water .
Earth has one moon
There are many planets that have more than one moon.
The moon revolves around the
earth as well as the Sun .
It takes 24 hours to revolve around the earth .
The moon light we see from Earth is the light from the Sun.
There are some small rocky bodies in the solar system that have
been left over from the formation of the planets.
These are called
asteroids.
Asteroids don't have
enough gravity to pull them into the shape of a ball .
Most of them lie in between Mars and Jupiter comets are balls of
rock and ice that grow tails as they approach the Sun
Comets come from far-away and imaginary place at the edge of the
solar system.
As it moves closer to the
Sun the glowing tails are visible
As Comus heat up gas and
dust are expelled and trail behind them .
All the stars that shine in the sky are like our Sun.
Many solar systems together
form a galaxy we live in the Milky Way galaxy which is spiral in shape .
Many galaxies together make the universe
