Planets in Our Solar System



The inner planets of Mercury, Venus, Earth,
and Mars are small and mostly solid. The
outer planets of Jupiter, Saturn, Uranus, and
Neptune are large and made mostly of
gases.
Between the inner and outer planets is a
belt of rocks called asteroids that orbit the
sun.
Comets are icy gaseous objects that leave
dust trails when their orbits come near the
sun.

The sun is the closest star
to Earth.
The sun is a big ball of hot
gases.
The sun gives off two kinds of
energy: light and heat. This is
called solar energy.
All eight planets orbit, or revolve, around the
sun.
The sun is so large that more than a million
Earths could fit inside it.
Sun and Stars



Stars come in all different sizes.
Our Sun is the standard used for comparing all
other star sizes.
The biggest stars are called supergiants.
Some are 500 times larger than the Sun.

Some of the smallest stars are white dwarfs.
Many are 1/100 the size of the Sun roughly the size of Earth
Planet
A planet is a large ball of rock or gas that
follows a path round the sun.
 There are eight planets.

Sun  Mercury, Venus, Earth, Mars, Jupiter,
Saturn, Uranus, Neptune
(My Very Educated Mother Just Showed Us Neptune!)
The solar system includes the sun
and eight planets.
Earth

Earth is the planet that we live on. It is the 3rd
planet from the sun. It is called a “Rocky
Planet,” because it is made of rocks.
Sometimes Earth is called the “Water Planet,”
because it is the only planet with the water we
need to live.
Earth orbits, or circles, the sun in 365 days, or
one year.
While it is orbiting the sun, it also spins like a
top! It spins 1 time in 24 hours, and that is why
Earth’s day lasts for 24 hours.
Earth is the only known planet where plants and
animals live.
