This is a simple Earth and Sun model. This model is not to scale in terms of size and distance.
The rotation and revolution speeds are roughly to scale. The Earth in this model is rotating at 1 second per rotation. It is also revolving at 365 seconds per revolution.
The Earth has a tile of 23.5 degrees on its rotation axis to the orbiting plane. There are also some background stars (points). This model can be easily created using VRMath2 Editor.
