If you mean "how many hours are IN one day", then there are 24 hours in a day.

24 hours are in one day...:)

24 hours
Mercury.
The planets with the shortest days are Jupiter (9 hours and 55 minutes) and Saturn (10 hours and 30 minutes.)
Mercury and Venus have the closest length of day among the planets in our solar system. A day on Mercury is about 58 Earth days, while a day on Venus is approximately 243 Earth days.
23 Hours 57 Minutes and 14 Seconds
One day on Haumea, a dwarf planet in our solar system, lasts about 4 hours. Haumea rotates on its axis very quickly compared to other planets and dwarf planets in our solar system.
No. There are 24 hours in a day. On Earth, that is pretty standard, but there could be other planets with a 50 hour day. Here are the approximate day lengths (defining a day by the time it takes a planet to rotate once on its axis) for the rest of the planets in the Solar System: Mercury: 58 Earth days Venus: 243 Earth days Mars: 25 hours Jupiter: 10 hours Saturn: 11 hours Uranus: 17 hours Neptune: 16 hours Unfortunately nothing in our own Solar System comes close, but we are always finding new planets and we might find one that has a 50 hour day someday.
The two planets that have the same length of and Earth day but shorter than a Earth day are Neptune and Uranus because a Earth day on Neptune is 18 hours and 30 minuets Earth time, And Uranus is 17.24 hours. Thus Neptune and Uranus is closest to an Earth day being below 23 hours and 56 min (24 hours rounding).
on Earth it's 24 but I'm not sure about other planets
