Phobos is in a synchronos orbit round Mars. This means that (like our moon,) it rorates once for each orbit it makes and it therefore always presents the same face to Mars.
The orbital (and thus rotational) period of Phobos is 7h 39.2min.
The speed of Earth's rotation on its axis determines the length of a day. A faster rotation results in shorter days, while a slower rotation results in longer days.
There are approximately 24 hours in one rotation of the Earth.
One day on Mercury is the equivalent of 58 days, 15 hours, and 30 minutes on Earth, This is because the planet has a very slow rotation.
9.9 Earth hours
Rotational speed is the propeller slipstream and engine torque all contrive to make the airplane turn left during takeoff.
The speed of Earth's rotation on its axis determines the length of a day. A faster rotation results in shorter days, while a slower rotation results in longer days.
Rotation (Retrograde) 243 Days, 0.5 Hours
There are approximately 24 hours in one rotation of the Earth.
9.075 hours
One day on Mercury is the equivalent of 58 days, 15 hours, and 30 minutes on Earth, This is because the planet has a very slow rotation.
0.3781 days.
24 hours to be exact.
16.1 hours
Neptune takes 16.1 hours to make a full rotation, which is equivalent to 0.673 Earth days.
No, not all planets in our solar system have days that are 24 hours long. For example, Venus has a rotation period longer than its orbital period, resulting in a day that is longer than 24 Earth hours. In contrast, Jupiter has a fast rotation speed, leading to a day that is about 10 hours long.
The smallest planet, Mercury, has a period of rotation of about 59 Earth days. Its slow rotation speed means that a day on Mercury (from one sunrise to the next) is much longer compared to a day on Earth.
10 hours 40 minutes.
