Sun – changes signs monthly On Venus, a day lasts about 243 Earth-days. Mercury spins slowly compared to Earth, so one day lasts a long time. This is the vernal equinox, and was chosen by planetary scientists as the start of a new year (A Mars year is 687 Earth days). He said 1 earth day and I said approximately 27 (I think) earth days. 176 days. Mercury’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. 1. 24 Earth days C. 93 Earth days D. 124 Earth days E. 176 Earth days Correct answer: E (176 Earth days) 2. 7-1, Comins and Kaufmann, Discovering the Universe, 7th Ed.) >That would mean Mercury is turning a lot slower than Earth. The Earth has aprox a 365.25 days in 1 year. Each sidereal day on Mercury takes 58.65 Earth days; it takes Mercury 58.65 days (2/3's of its year) to rotate around its axis once. This is how long it takes for the Earth to revolve once around the Sun. Mercury makes a complete orbit around the Sun (a year in Mercury time) in just 88 Earth days. It has a long daytime (which lasts 58.65 Earth days or almost an entire Mercurian year, which is 88 days long) Venus rotates VERY slowly. That may seem long, but think about this: its year is only 88 Earth days long! Long Days, Short Years One day on Mercury (the time it takes for Mercury to rotate or spin once with respect to the stars) takes 59 Earth days. Martian New Year. It is daytime for one Mercurian year, and nighttime for one Mercurian year. In that sense, it remains daytime for a full year on Mercury and it stays night for one full year also. A. Venus takes 224.65 Earth days to complete one revolution around the Sun, which is also the length of a Venus year. Mercury takes 59 Earth days to make one full rotation. A star can be found at one location in the sky one night and then the time it takes to find the star in that same position the next night is a sidereal day. Mercury has the longest day … Because days on Mercury are very long, an Earth year is 6.22 Mercury days, if a day is defined as how long it takes Mercury to rotate on its axis.
