Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relationship is called spin–orbit resonance, and sidereal here means 'relative to the stars'. Consequently, one solar day (sunrise to sunrise) on Mercury lasts for around 176 Earth days: twice the planet's sidereal year.

Physical characteristics. Mercury is one of four terrestrial planets in the Solar System, which means it is a rocky body like Earth. It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 kilometres (1,516.0 mi). [4] .
Mercury has a diameter of 3,032 miles (4,879 km) making it a little more than one third the size of Earth. If Earth were the size of a baseball, Mercury would be about the size of a golf ball.
