Mercury''s orbit duration is 87. 97 Earth days, while its rotational period is 58. 646 days, leading to an unusual situation where a year on Mercury is about half the length of a day.
A year on Mercury is only 88 days long, or just over two months
Mercury''s distance from the Sun varies depending on where it is in its orbit, but it is generally very close to this massive star. Its orbital period in fact
Orbit and Rotation of Mercury The planet with the most eccentric orbit in the Solar System is Mercury. The eccentricity for the planet is 0.21 and its distance from
Orbit around the Sun: Because Mercury is so close to the Sun, it has the smallest orbit of all the planets. Mercury''s year (the time it takes to orbit the Sun one time) is 88 Earth days long.

Mercury is the first planet from the Sun and the smallest in the Solar System. It is a rocky planet with a trace atmosphere and a surface gravity slightly higher than that of Mars. The surface of Mercury is similar to Earth''s Moon, being cratered, with an expansive rupes system generated from thrust faults, and bright ray systems, formed by ejecta. Its largest crater, Caloris Planitia, has a diameter of 1,550 km (960 mi), which is about o
