How far above us are satellites?
Can you explain in layman's terms just how high in the sky satellites are orbiting? I've always been fascinated by space exploration and technology, but I'm not quite sure about the specific altitudes and distances involved. Is there a range of altitudes where most satellites are placed, or do they vary widely depending on their purpose? Also, what kind of impact does the Earth's atmosphere have on their orbits, if any? I'd appreciate a clear and concise answer that doesn't require a deep understanding of physics or astronomy.
