How many hours is one night on earth?

Answer 1

The actual period of night on Venus would be about 58.4 Earth days (half of the apparent sunrise-to-sunrise time of 116.75 days). Of course, you would not see sunset or sunrise from the surface, only a change from bright to dark to bright again after two months.

Although Venus has a rotation period (sidereal day) of about 243 days, its reverse spin and its shorter year (225 Earth days) combine to make for a shorter solar day.

Answer 2

That depends every much on where you live. Anywhere from several weeks to a few minutes. At the equator, twice a year it is exactly 12 hours.

Answer 3

A complete rotation of Jupiter takes slightly less that 10 hours. A night on Jupiter would be a little bit less than 5 hours.

Answer 4

One night on Earth is typically defined as the period from sunset to sunrise, which spans roughly 12 hours.
