Why are some planets very cold?

Answer 1

1. Mars is considerably farther from the Sun than Earth and therefore receives less sunlight to warm it.

2. It's atmosphere is very thin, so it cannot produce a substantial greenhouse effect and quickly loses the heat it gains in the daytime at night becaus the atmosphere is too thin to hold onto it.

Answer 2

Here are the following two main reasons why the temperature on Mars is significantly colder (with average temperatures of -80 F or -60 C) than the temperature on the Earth:

• Mars is about 1.67 times farther away from the Sun than the Earth. This is too far from the Sun to get as much of the Sun's energy and heat as the Earth does, so as a result, Mars gets lower energy and heat than the Sun and is colder than the Earth.

• The Martian atmosphere is only about 1% as thick as that of the Earth, so it is less capable of trapping heat. This is the reason why at night, when one portion of Mars is turning its back on the Sun, the temperature on that portion of the Martian surface drops to over -150 F (-100 C).

However, on Mars, during a warm summer afternoon near the equator, temperatures can rise to a surprising 64 F (18 C), but during those long cold winter nights at the poles, temperatures can reach about -195 F (-125 C).

Answer 3

It is because the other outer planets are very far from the sun and get almost or no Sun light which makes it very very cold.

Answer 4

This is mainly due to its distance from the sun - its much further away from the heat source than earth. It also has a very thin atmosphere which doesn't help.

Answer 5

It can reach temperatures to -123c to 37c
