Web7 aug. 2024 · The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March. Web18 jun. 2024 · It takes about 59 Earth days for Mercury to complete just one rotation on its axis. The time for one rotation is only barely faster than Mercury’s year, which is 88 Earth days. So that means Mercury’s year is only 1 1⁄2 Mercury days long. Learn more about orbiting Earth: up through the atmosphere.
