One, that being essentially the definition of a planet's year.
It is believed Mercury developed around the same time as the Earth did, about 4.6 billion years ago; as did all the other planets of the solar system.
This is how long it takes the first 5 planets to orbit the Sun. Mercury: 0.2 years Venus:0.6 years Earth: 1 year Mars: 2 years
The length of a planet's orbit around the Sun varies depending on the distance from the Sun. For example, Mercury has an orbit of about 88 Earth days, while Neptune's orbit is around 165 Earth years.
The "Solar day" on Venus. Or, the "Sidereal day" on Mercury.
Mercury has a year that is only 88 days long.
88 days, which is about 0.2 years.
Mercury: 0.2408 earth yearsNeptune: 164.8 earth years.
Mercury takes about 88 Earth days to complete one orbit around the sun. Its orbit is the closest to the sun out of all the planets in our solar system.

A year on other planets varies depending on the planet's orbit around the sun. For example, a year on Mercury is about 88 Earth days, while a year on Mars is about 687 Earth days. The farther a planet is from the sun, the longer its year typically is.
Mercury: 0.2408 earth yearsSaturn: 29.46 earth years.
Mercury has no moons.
