How long does it take for Mercury to orbit its own axis?
It would be a very long workday from an Earth perspective! This is because Mercury’s rotation around its axis lasts 59 days, and it takes 88 days to move around its orbit around the Sun.
How long is a day on Mercury’s rotation on its axis?
58.646 Earth days
A planet’s day is the time it takes the planet to rotate or spin once on its axis. Mercury rotates very slowly compared to Earth so a day on Mercury is much longer than a day on Earth. A day on Mercury is 58.646 Earth days or 1407.5 hours long while a day on Earth is 23.934 hours long.
How many times does Mercury spin on its axis?
Mercury rotates in a way that is unique in the Solar System. It is tidally locked with the Sun in a 3:2 spin–orbit resonance, meaning that relative to the fixed stars, it rotates on its axis exactly three times for every two revolutions it makes around the Sun.
How long is Mercury’s orbital path?
88 Earth days
Mercury revolves around the Sun in an elliptical orbit at a mean distance of 58 million km; the orbital period is 88 Earth days or 0.24 Earth years.
Why does Mercury rotate so slowly?
The sun’s gravitational pull speeds up or slows down Mercury’s rotation depending on where the oblong-shaped planet is on its elliptical orbit. Jupiter’s gravity tugs on Mercury’s orbit, and changes the innermost planet’s distance to the sun and the way that our sun influences on Mercury’s spin.
Does Mercury rotate on its axis?
Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. Mercury does not tilt on its axis, therefore the Sun would constantly be situated on the horizon at the poles). The image above shows how Mercury completes three rotations around the Sun for every two orbits.
Why is Mercury’s orbit unusual?
Mercury’s Unusual Elliptical Orbits Mercury’s orbit around the Sun is also less circular—more elliptical—than any other planet. This is because Mercury is on average 2 1⁄2 times closer to the Sun than the Earth. Now, we say ‘on average’ because Mercury’s distance from the Sun changes a lot during its orbit.
How many moons are orbiting Mercury?

Is Mercury’s year shorter than its day?
To break it down, Mercury takes roughly 88 Earth days to complete a single orbit around the Sun. Between this rapid orbital period and its slow rotational period, a single year on Mercury is actually shorter than a single day!
Why is Mercury’s orbit the shortest?
Because of its nearness to the Sun—its average orbital distance is 58 million km (36 million miles)—it has the shortest year (a revolution period of 88 days) and receives the most intense solar radiation of all the planets.
How long does it take for Mercury to rotate on its axis?
Home Science Astronomy Planets. How Long Does It Take for Mercury to Rotate on Its Axis? It takes a total 1407.5 hours, or 58.646 Earth days, for Mercury to make a complete rotation on its axis. A day on Earth is only 23.934 hours long, which pales in comparison to Mercury’s extremely long days.
How many days does it take mercury to orbit the Sun?
It rotates on its axis three times for every two orbits it makes around the sun. That means that a day on Mercury (sunrise to sunrise) is two it says that the sidereal rotation period is 1407.5 hours (58.646 earth days). That is the time it takes Mercury to spin 360° about its spin axis. We do not call that orbiting though.
How long is a year on Mercury compared to Earth?
Mercury likes to keep things simple. Mercury spins slowly compared to Earth, so one day lasts a long time. Mercury takes 59 Earth days to make one full rotation. But a year on Mercury goes fast. Because it’s the closest planet to the sun, it goes around the Sun in just 88 Earth days.
Where is the Sun at the poles of Mercury’s orbit?
(This is assuming an observer is not at one of the poles. Mercury does not tilt on its axis, therefore the Sun would constantly be situated on the horizon at the poles). The image above shows how Mercury completes three rotations around the Sun for every two orbits.
