Answer 9

Inner planets - the terrestrial (rocky) planets
Mercury, Venus, earth, mars

Outer planets - the gas giants
Jupiter, Saturn, Uranus, Neptune

Asteroid belt - including the dwarf planet Ceres

Kuiper belt objects (such as pluto)

Comets (balls of ice)

Question 10

How does the planets distance from the sun effects its temperature

Answer 10

The further the planet from the sun, the colder its temperature is (apart from Venus, because of its thick atmosphere)

Question 11

Define exoplanet

Answer 11

is a planet that is orbiting a star that is not the sun

Question 12

Learn this phrase

Answer 12

gravity pulled gas and dust together to form the Sun about 5 billion years ago. The planets then formed from a spinning disc of gas and dust around the sun.

Question 13

Explain the amount of time the moon takes to orbit the earth

Answer 13

The moon orbits the earth every 27 days and 7 hours. It takes the same amount of time to spin on its axis so we always see the same side.
