Quick Answer. The average daytime and the average night-time temperature of Uranus is -193 degrees Celsius. There is no change in the temperature from day to night for the seventh planet in the solar system. Uranus is the coldest planet in this solar system, even though it is not the furthest planet from the sun.
This means that a single year on Uranus lasts as long as 30,688.5 Earth days. However, since it takes 17 hours 14 minutes 24 seconds for Uranus to rotate once on its axis (a sidereal day). And because of its immense distance from the Sun, a single solar day on Uranus is about the same. This means that a single year on Uranus lasts 42,718 Uranian solar days.
