The screen at startup is the earth.The equatorial inclination angle of the earth is 23.4 degrees.Equatorial inclination angle is the angle between the equatorial plane and the orbital plane of a planet that revolves while rotating.
The equatorial inclination angle of the mercury is 0.027 degrees.The rotation axis is upright almost vertically.
The equatorial inclination angle of the venus is 177.36 degrees.The rotation axis is almost completely inverted, and it rotates in the opposite direction.
The equatorial inclination angle of the mars is 25 degrees.The axis of rotation is a gradient close to the earth.
You can change the rotation speed of the planet.The equatorial inclination angle of the jupiter is 3.08 degrees.The rotation axis is upright almost vertically.
When you press the button, the angle of the sun changes by 30 degrees each time.
The fastest thing is one revolution per second.The slowest thing is one rotation in 300 seconds (5 minutes).
When checked, reverse rotation will occur.
