惑星の自転

-The screen at startup is the earth. The obliquity angle of the earth is 23.4 degrees. The obliquity angle is the angle between the orbital plane and the equatorial plane of a planet that revolves while rotating.
-Mercury's obliquity angle is 0.027 degrees. The axis of rotation stands upright almost vertically.
-Venus's obliquity angle is 177.36 degrees. The axis of rotation is almost completely inverted and rotates in the opposite direction to many planets.
-Mars' obliquity angle is 25 degrees. The axis of rotation is an inclination close to the earth.
-Jupiter's obliquity angle is 3.08 degrees. The axis of rotation stands upright almost vertically.
-The light from the sun can be changed by 30 degrees.
-You can change the rotation speed of the planet. The fastest is 1 second, and the slowest is 300 seconds to make one revolution.
-It can rotate in the reverse direction, which is not possible in the natural world.
