Venus has a surface temperature that is closest to Earth's temperature, with an average of about 864 degrees Fahrenheit (462 degrees Celsius) due to its thick atmosphere of carbon dioxide which creates a greenhouse effect.
All eight planets have a surface temperature, though it varies as the planets distance from the sun varies. Closer planets to the sun generally have a higher surface temperature, while further planets have a colder surface temperature.
Saturn is a gas giant and does not have a solid surface, so it doesn't have a "high temperature" like rocky planets. However, it has a hot upper atmosphere with temperatures around -150 degrees Celsius.
Saturn's temperature is believed to be about -270 degrees Fahrenheit or -167 degrees Celsius, which is cold. It's so cold because its so far away from the sun. The hottest planets are the inner planets which consists of Mercury and Venus. Earth is in the Goldilocks zone witch is where it is not too hot and not too cold but the right temperature for life. Anything further away from the sun than the Earth is, is way below 0 degrees Celsius as mars is -250 degrees Celsius.
Check out NASA's: "Planetary Fact Sheet" Web page. That's pretty good. There are slight differences in the answers to this question, depending on the source of information that you use.
20 degrees Celsius is about 68 degrees Fahrenheit. This is an ideal temperature for a planet to support carbon-based life, as water is a liquid between 0 and 100 degrees Celsius, or 32 and 212 degrees Fahrenheit.
The vacuum in space only has one temperature: -273.15 degrees Celsius. The planets' temperature do vary, though.
Uranus has a very cold average temperature of about -224 degrees Celsius (-371 degrees Fahrenheit). This makes it one of the coldest planets in our solar system.
Neptune, the coldest and furthest of our solar systems eight planets.
Neptune(If you include dwarf planets it is Eris)
Neptune's maximum temperature can reach up to about -200 degrees Celsius (-328 degrees Fahrenheit), making it one of the coldest planets in our solar system. Its minimum temperature is around -218 degrees Celsius (-360 degrees Fahrenheit). These extreme temperatures are due to Neptune's distance from the Sun, its thick atmosphere of hydrogen, helium, and methane, and its lack of a solid surface to retain heat.
Venus has the highest average surface temperature among the inner planets. Its thick atmosphere traps heat, leading to extreme temperatures of around 467 degrees Celsius (872 degrees Fahrenheit) on its surface.
Venus has a surface temperature that is closest to Earth's temperature, with an average of about 864 degrees Fahrenheit (462 degrees Celsius) due to its thick atmosphere of carbon dioxide which creates a greenhouse effect.
All eight planets have a surface temperature, though it varies as the planets distance from the sun varies. Closer planets to the sun generally have a higher surface temperature, while further planets have a colder surface temperature.
If you're talking about actual space, as in vacuum, the only temperature is about -273.5 degrees Celsius, as no atoms move in space. On planets and stars, temperature can vary dramatically, from the temperature of vacuum to the core of the hottest star (could be 40 million Celsius).
Actually, Neptune is not hot but, it is to cold because it's mean surface temperature is -200.15 C ( 387.27 F).For more information about the Planet Neptune or the other Planets, visit the link below:
WARMER. Comment: It's not very warm though. The average temperature is well below zero degrees Celsius.
