Objects in our solar system

^{Objects made of ice, gas and dust and orbit our sun are called:}

• Asteroids
• Comets
• Meteroids
• Meteors

Asteroids "hang out" in our solar system in a place called:

• The Kupier Belt
• The Oort Cloud
• The Planetary Rings
• The Asteroid Belt

One similarity between asteroids, comets and meteoroids is that they all:

• are made of rock
• come from the Asteroid Belt
• come from the Oort Cloud
• orbit the sun

Which group of planets are large and mostly made of gas?

• Inner planets
• Outer planets
• asteroid belt

How many stars are in our solar system?

• one

• two

• many

Which planets are the inner planets starting with the one closest to the sun?

• Earth, Mars, Jupiter, Venus

• Mars, Venus, Earth, Mercury

• Venus, Earth, Neptune, Mars

• Mercury, Venus, Earth, Mars

The orbital speeds of planets closer to the Sun will be faster than planets farther away because.....

• The gravity decreases as the distance between the objects increase.

• The gravity increases as the distance between the objects decrease.

• The gravity increases as the mass of the object increases.

• The gravity between the objects decrease as the objects warm up.

How do scientists believe gravity influenced the formation of the planets in our solar system?

• A large cloud of gas and dust ignited into a planet.

• Gravity pulled the planets out of the Sun.

• A large explosion created the planets.

• Large pieces of debris clumped together to form planets.
