Did You Know: Space – How cold is it in space?
In the huge areas between the stars and galaxies, space can get very, very cold. In these regions, the temperature can drop as low as -454ºF (-270ºC).
However, the objects in space, such as stars and planets, can be lots of different temperatures.
Do other planets have summers and winters?
Uranus
Uranus has four seasons that last around 21 years each.
The planet spins on a very tilted axis. This means that during summers and winters, the summer side of Uranus is in daylight for 21 years and the winter side is in darkness for 21 years too.
The sun
This is the hottest object in the solar system. The surface temperature of the sun is around 11,000ºF (6,000ºC).
Too hot to ever visit!
Supernova
When a huge star explodes, it can become a supernova and temperatures can reach up to 99,000,000ºF (55,000,000ºC).
The moon is a world of extreme temperatures. In the sunlight, it can be as hot as 253ºF (123ºC).
The coldest parts can reach -387ºF (-233ºC).
Venus
The hottest planet in the solar system, Venus has a thick atmosphere that helps the surface reach temperatures as high as 880ºF (470ºC).
Neptune
Temperatures on Neptune average about -353ºF (-214ºC). Its largest moon, Triton, is even colder, with temperatures dropping to -391ºF (-235ºC)!
Earth
The average temperature on the Earth is around 59ºF (15ºC). However, this can change depending on the seasons and the location on Earth.
Boomerang Nebula
Thousands of light-years away from the Earth, the Boomerang Nebula is the coldest known object in the universe. Inside this gas cloud, temperatures can be as low as -458ºF (-272ºC).
