What is the rotation period of mercury?

This means that a single day on Mercury last about 0.646 times as long as a single year. The planet's equatorial rotational speed is 10.892 km/h. These periods are given in solar days. In sidereal days Mercury rotates every 58.647 days and orbits twice during every three rotations. read more

The rotation of Mercury is a little strange to Earth bound creatures. It rotates on its axis very slowly compared to its orbital period. One rotation takes 56.85 Earth days, while one orbital period only takes 88 Earth days. This means that a single day on Mercury last about 0.646 times as long as a single year. read more

This figure is two-thirds of the time that Mercury takes to complete one orbit of the Sun. Astronomers use the term "spin-orbit resonance" to describe the ratio of a rotation on a planet's axis to the time it needs to complete an orbit of the Sun. Therefore, Mercury has a spin-orbit resonance of 3:2. read more
