The planet Mercury rotates very slowly, taking almost 59 Earth days to turn once (58.646 days). However, it also orbits the Sun very rapidly, about once every 88 Earth days, which combines with the slow rotation to create an unusual situation.

The solar day (sunrise to sunrise) on Mercury is 176 Earth days, or twice the length of its year! This further increases the drastic temperature extremes that the surface experiences, alternately seared for months by solar heat and then frozen for months as it turns away from the Sun.

*Due to the tidal effects of the Sun's gravity, the equatorial rotation of Mercury is only about 10 km/hr (far slower than Earth's 1600 km/hr). This means a "day" on Mercury is about 1400 Earth hours (58.6 days).

(see the related question)

58.6461 Earth Days, rounded to 58.65 Earth Days

is the correct answer!

That's the rotation period, also known as the "sidereal" day".

The "solar day" is 3 times longer, at about 176 Earth days.

What is mecury's rotation?

A solar day on Mercury lasts about 176 Earth days, which is about twice as long as Mercury's orbital period, (roughly 88 Earth Days). As a result, a Mercury year is about 0.5 Mercury days long, and one Mercury day lasts approximately two Mercury years.


How long are years in earth in mercury times?

An Earth year is 4.152091 Mercury years. Because days on Mercury are very long, an Earth year is 6.22 Mercury days, if a day is defined as how long it takes Mercury to rotate on its axis. Because Mercury rotates so slowly, on Mercury the sun makes a complete journey around the sky every 175.9 Earth days. If a day is defined as how long it is from sunrise to sunrise, an Earth year is 2.076 Mercury days.

How long does it take for Mercury to rotate on its axis?

It takes about 59 Earth days (58.66 days) for Mercury to make one rotation.However, its "day" is extended due to the extremely short orbital period of 88 Earth days : a "sunrise to sunrise" solar day is 176 Earth days long (2 Mercury years).This is the source of the saying "On Mercury, a day is twice as long as a year."
