Mercury has the most eccentric orbit of all the planets in the Solar System; its eccentricity is 0.21 with its distance from the Sun ranging from 46,000,000 to 70,000,000 km (29,000,000 to 43,000,000 mi). It takes 87.969 Earth days to complete an orbit. The diagram illustrates the effects of the eccentricity, showing Mercury's orbit overlaid with a circular orbit having the same semi-maj… WebMercury speeds around the Sun at nearly 47 kilometres per second - almost 60% faster than Earth's orbiting speed. How long is a day on Mercury? Days on Mercury are very long because the planet rotates very slowly. One day-long spin lasts for 59 Earth days. But because of its fast orbit, one Mercury year takes 88 Earth days. tfoot fixed bottom

WebNov 30, 2024 · If you do want to take Mercury's rather elliptical orbit into account, you can note that after 3 times 115.75 = 347.25 days, the Earth (and hence Mercury) are at almost the same places in their orbit, so a 'relatively close' closest approach is followed by another one 347 days later. Share Improve this answer Follow edited Nov 30, 2024 at 10:02 WebEarth is on average ten times closer to Mercury than Jupiter, but missions to both planets can take a similar amount of time to reach their science orbits.
