Did I understood that right? By moving the time changes? I mean the clock on the airplane could be slower because its pretty cold up there, and the colder it is the slower things go. But that is no change of time(?)

In anyway, what I am realy woundering about. Planets are moving realy fast and realy slow. And (their) movement depends from the view of other objects, what means there is no real speed. From point of view of itself it´s not moving. But time is going on. All planets time is going the same (or am I wrong). Doesn´t matter if you are on the moon or earth. But moon and earth move with different speed. And what about the sun. It´s not moving(?) but it is reacting real fast with all it´s burnings and explosions. So why isn´t the suns time = 0?yeah, yeah, I know. The sun is moving for sure. But still it´s time is going same as on earth I guess when I watch these explosions there. In these movies they look slow because are so big and far away. Like watching the horizon when driving.
