WebThis would be caused by the large tidal forces exerted on Mercury by the Sun. Synchronous rotation occurs when the period of revolution equals the period of rotation (i.e. a ratio of 1:1). Accurate measurements of Mercury using radar echoes bounced of the planet revealed that its period of rotation (58.65 days) is equal to two thirds its orbital period … WebMercury is the closest planet to the Sun with an average distance of 0.387 AU or 5.79 x 10 7 km. It takes 88 Earth days to orbit the Sun, and rotates very slowly at a rate of 1 rotation every 58.7 Earth days. Its mass is 3.3 x 10 23 kg or 0.055 Earth masses. It has no moons, little to no atmosphere and generally a very hot surface.

WebIt only takes 88 days for Mercury to orbit around the Sun at 47.8 km/sec (29.7 miles/sec). A typical year on Mercury would take 88 Earth days. Because of Mercury’s ever changing distance from the sun and its 3:2 spin-orbit resonance the temperature on Mercury’s surface is complex and varied. A day in Mercury is twice as long as a year in Mercury. http://cseligman.com/text/sky/rotationvsday.htm assoesaip
How Long Is a Day on Other Planets? - ThoughtCo
WebRecently (1999–2005) the average annual length of the mean solar day in excess of 86400 SI seconds has varied between 0.3 ms and 1 ms, which must be added to both the … WebA sidereal day is about 23 hours and 56 minutes long. A solar day is longer because the earth is not just rotating but it is also in orbit around the Sun. In the 23 hours and 56 minutes it takes for the earth to complete its sidereal day it has gone about 1/365th of its way to complete its orbit around the Sun. WebBecause of Mercury’s slow rotation (once every 58.646 days) and its rapid orbital speed (47.362 km/s), one day on Mercury actually works out to 175.96 Earth days. A Year on Venus The second closest planet to our Sun, Venus completes a single orbit once ever 224.7 days. This means that a single year on Venus works out to about 0.6152 Earth years. associativity rule in java
