Mercury, has 24 hours in a day, the same as the earth and all the other planets in the Universe.

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

There are 24 hours in a day.

24 hours

Mercury.

Of the four inner planets (Mercury, Venus, Earth, and Mars), Earth has the shortest day at 23 hours and 56 minutes sidereal rotation period. That's the "sidereal day". The day that lasts exactly 24 hours is called the "solar day". For both "days", Earth has the shortest day.

The outer planets have longer rotation periods than the inner planets. For example, a day on Jupiter, an outer planet, is about 10 hours long, while a day on Earth, an inner planet, is about 24 hours long.

The planets with the shortest days are Jupiter (9 hours and 55 minutes) and Saturn (10 hours and 30 minutes.)

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.

Earth takes approximately 24 hours to complete one full rotation on its axis. The other planets in our solar system have varying rotation periods; for example, a day on Mars is about 24.6 hours, while a day on Venus is about 243 Earth days.

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.
