stars in our Galaxy!

It creates light and

heat through nuclear

fusion

Planet Earth

Earth is the only planet in our solar system that has liquid water and a breathable atmosphere

Over 70% of Earth is covered by water

Earth is the only planet in our solar system that can sustain life

The Asteroid Belt

The asteroid belt is located between Mars and Jupiter

It consists of rocky bodies that range in size between boulders and small moons

It’s believed that this “belt” may once have been a planet that collided with another very large body in space, and broke into millions of pieces

Uranus

• This bluish planet is made of mostly methane gas

• Like, Saturn, it also has a distinctive ring system

• It is the only planet that rotates flopped over on its side

Neptune

This gigantic planet also has a storm raging on its surface, just like Jupiter. It’s called “the great blue spot”.

Pluto In 2006, astronomers

decided that Pluto, by definition, is no longer a planet.

It is considered a “protoplanet”, or dwarf planet, due to its small size and strange orbit.

Pluto has one moon; Charon

CometsComets

Comets are like “dirty snowballs”. Comets are like “dirty snowballs”. They are made of mostly ice and They are made of mostly ice and and rockand rock

They usually orbit the Sun at They usually orbit the Sun at great distances; much further out great distances; much further out than even Pluto!than even Pluto!

Sometimes, a comet is knocked Sometimes, a comet is knocked out of this distant orbit. As it out of this distant orbit. As it approaches the Sun, its ice approaches the Sun, its ice begins to melt and forms its begins to melt and forms its characteristic tailcharacteristic tail
