How long is one day in rotation time on Mercury?

Answer 1

All planets have a different length of "day." Depending on whether or not you consider a day to be one full rotation. The lengths of days are as follows:

Mercury: 175.94 Earth Days.

Venus: 116.75 Earth Days.

Earth: 24 Hours

Mars: 24 Hours, 39 minutes, and 35.24 seconds

Jupiter: 9 Hours, 59 minutes, 33 seconds

Saturn: 10 hours, 32 minutes, 35 seconds

Uranus: 17 Hours, 14.4 minutes

Neptune: 16 Hours, 6.6 minutes

Pluto: 6 days, 9 Hours, and 17 minutes.

Answer 2

One day on Mercury, measured as the time it takes for the planet to rotate once on its axis, lasts about 59 Earth days. Mercury has a slow rotational period, which means its day is much longer than its year.
