WebMercury’s period of rotation (how long it takes to turn with respect to the distant stars) is 59 days, which is just two-thirds of the planet’s period of revolution. Subsequently, … Webtion of Mercury around the sun and his rotation upon his axis were coin-cident, each requiring a period of about 88 days. In the year 1666, Domenico Cassini, an Italian, estimated the period of the rotation of the planet Venus at 23 hours and 21 minutes. Another observer placed it at 24 days, 8 hours; Schroeter gave it a period of 23 hours …

Web9 feb. 2024 · On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast. Jupiter takes just 10 hours to complete one rotation. Saturn takes 11 hours, Uranus takes 17 hours, and Neptune takes 16 hours. WebMercury is an extreme planet in several respects.

Earth: 365 days. … Web29 jan. 2016 · To put it simply, Mercury has an orbital period of 88 days (87.969 to be exact), which means a single year is 88 Earth days – or the equivalent of about 0.241 Earth years. But here’s the thing. WebPrior to 1965, astronomers believed that Mercury's sidereal rotation matched its orbital period of 88 days (synchronous rotation). This belief was reinforced by the chance coincidence of six 58.65-day rotation periods (352 days) closely matching the synodic period of Mercury's maximum elongation (350 days). iomega ix2-200 firewire 3.2.12.30116
