what are the coldest and hottest planets in the solar system?

Answer 1

The hottest planet is Venus with a suface temperature of 870F, the coldest is Neptune with a temperature of -472F?.

If Pluto was still a planet, Neptune and Pluto would have the same temp.

Venus Hottest
Mercury
Earth
Mars
Jupiter
Saturn
Uranus
Neptune Coldest

Answer 2

Mercury has the highest temperature variance, it is not the hottest and coldest. "The axis of rotation is almost perpendicular to the orbital plane, so Mercury does not have opposite seasons in each hemisphere, as Earth has. Instead, the temperature at the equator varies as the planet's distance from the Sun changes during its orbital travels. The maximum temperature is 700K (427C), but the minimum only 90K (-183C). Mercury has very little atmosphere so the surface cools down rapidly on the night side. By contrast, Venus, with its thick atmosphere, maintains a fairly stable temperature which is slightly higher than the maximum on Mercury."

Answer 3

The coldest planet is Neptune, measured at about -210 degrees Celsius at its cloud tops. The hottest planet is Venus. Though it is not the closest to the sun, it has a very thick atmosphere that measures as about 95 atms, or atmospheres. To give you an idea of how thick that is, Earth's atmosphere is one atm. Imagine 95. Venus is measured at roughly 427 degrees celcius.

Answer 4

venus is the hottest and neptune is the coldest. neptune because pluto isnt a planet anymore, and venus because of the greenhouse gas effect gone extreme

Answer 5

Hottest is venus because of the green house effect
Coldest is neptune - pluto is no longer a planet

Answer 6

hottest is Mercury, coldest is pluto
