B Inner-atmospheric orbit

  1. Mar 25, 2017 #1
    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.
