AI Thread Summary
Satellites cannot achieve stable orbits within Earth's atmosphere due to significant atmospheric drag and friction, which would hinder their ability to maintain orbital velocity. While theoretically, a sufficiently fast satellite could orbit at altitudes between the Mesosphere and Exosphere, practical challenges make this unlikely. The discussion also touches on the fictional concept of the Death Star, clarifying that it was powered by a fusion reactor rather than solar panels. Overall, the consensus is that atmospheric conditions create insurmountable obstacles for sustained satellite orbits. The complexities of aerodynamics and friction render low-altitude orbiting impractical.

Hi, was just wondering if gravitational orbit be achieved inside the Earth's atmosphere. Or how close a satellite can be to the ground?

Additionally, would the Death Star have been completely covered in solar panels?

Which part of the atmosphere are you referring to? And no, if I'm correct, the Death Star had a fusion reactor.
 
Orbit can be falling when tangential velocity can path beyond horizon when vertical is less than escape velocity. a sufficiently såeedy satellite could orbit the Earth within the atmosphere, but friction would be a huge practical problem.
 
I suppose I would like to know if something can orbit between the Mesosphere and the Exosphere without using rockets.
Didn't think of friction- that is problematic.
 
It is possible, but it's unlikely

Aerodynamics is too.

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
