Asteroid BeltAsteroid Belt• Possible remains
of another planet
• Or leftovers that never finish forming into another inner planet

Asteroid BeltAsteroid Belt• Smaller
asteroids collide together to form larger asteroids
• After a great period of time a new planet can form
• Smaller asteroids collide together to form larger asteroids

Kuiper BeltKuiper Belt
• Object out around Pluto are called Kuiper Belt Objects or KBO’s
• They are small icy objects
• Object out around Pluto are called Kuiper Belt Objects or KBO’s
• They are small icy objects
Kuiper BeltKuiper Belt• Over 900 KBO’s
have been discovered since 1990
• Most of the larger ones are about the size of Pluto
• Over 900 KBO’s have been discovered since 1990
• Most of the larger ones are about the size of Pluto
And Beyond….And Beyond….• Beyond the KBO’s is
another region called the Oort cloud
• Anything beyond 50 AU is in the Oort Cloud
• 1 AU is equal to the distance between the Earth and the Sun
• Beyond the KBO’s is another region called the Oort cloud
