No one can answer these, because the points raised are really unscientific.
Some educated Muslims try to answer it diplomatically that sun rotates in orbit. But that is only half of what Kuran says. The full verse of Kuran says the sun rotates around the earth and earth is the center. This is exactly what Aristotole said. Educated muslims try to hide the second part ("around the earth" ) and teach their students like that.
