The Solar System

The Sun is a star. Center of the Solar System 109 x bigger than Earth ~12,000°F

The Solar System also has asteroids and comets.

Asteroids are rocky. (They look like big potatoes.)

Comets have a lot of ice.

Comets also have rock, dust, and dirt. They are called “Dirty Snowballs.”

Asteroids and comets orbit the Sun.

Comets have two tails! They point away from the Sun.

Comets leave behind dust and dirt. Shooting stars are called “meteors.”

Making a Comet 1)100ml water 2) a little bit of sand 4) more water 3) crushed dry ice

I will wear gloves when I touch the ice.
