On Mercury, it is daytime for one year, and night for one year. Another really strange thing, Mercury’s orbit has the … Mercury is the planet closest to the Sun and on Mercury the length of a day lasts 58 days, 15 hours on Earth. In fact, one day is actually as long as two years on Mercury. This makes it about two-fifths the size of Earth. "Planets that orbit closer to the Sun than Earth have shorter years than Earth. Due to its rapid orbital period and slow rotation, a day on Mercury lasts 176 days, which is twice as long as a year on that planet!

It takes about 176 Earth days for Mercury to rotate on its axis (from sunrise to sunrise), while Earth takes only 24 hours. See today's front and back pages, download the newspaper, In the solar system, a year is determined by how long it takes for a planet to revolve around the sun, and a day is determined by how long it takes for a planet to completely rotate on its axis. A single day on Mercury lasts approximately 58 Earth days, 15 hours and 30 minutes. Sometimes the sun comes to a complete stop, then seems to move backward for a while, then moves forward again in a loop back to the position where it had stopped at previously, before moving forward. The sun also sometimes looks larger and sometimes smaller, and decreases in size to the point where background stars can be seen. Mercury has the most eccentric orbit of all the planets; 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).

Earth is about 150 million kilometers from the sun. The diagram illustrates the effects of the eccentricity, showing Mercury's orbit overlaid with a circular orbit having the same semi-major axis. To obtain length, measure from the top of the gearcase housing (base of the water pump plate) to the top of the shaft. This varying distance to the Sun leads to Mercury's surface being flexed by tidal bulges raised by the Sun that are about 17 times stronger than the Moon's on Earth. It takes Mercury about 88 Earth days to orbit the sun, while Earth takes 365 days. "And we also have to make sure we don't run into any other orbiting objects - like planets or asteroids along the way. It takes about 176 Earth days for Mercury to rotate on its axis (from sunrise to sunrise), while Earth takes only 24 hours. It takes 87.969 Earth days to complete an orbit. Mercury has an unusual length of day when compared to most of the other planets in the solar system.Mercury rotates on its axis very slowly, while it orbits the sun quickly.
