It appears busy, however it's not clear what is orbit of satellite and planet ?
Can the satellite fly like this way ? Why ?

wswu,

You cann't just enjoy the effect of computer graphics in 3D.
You must put the meaning in your works by a scientific way.

That's rudimental requirement for newbie, not for senior member or Simwe competition champion winner.
They are expected to demonstrate the quality in Simwe science and technology forum.

The earth and satellite model is good. However, the orbit is less correct.
We cann't plot any elliptic curve and says that is a satellite orbit.
The motion of satellite follows their own rule, which related with mass and radius of two objects.

I am happen to see you put your 3rd version here.
