why does the iss move through the sky really quickly yet planets further out barely seem to move?
In: Physics
Because ISS is in a lower orbit (closer to Earth) than most satellites, it has to move much faster to stay in orbit and not fall on Earth.
Satellites that are in higher orbits appear to move slower, and satellites in geostationary orbit (which is the farthest, I believe) appear to stand still because they spin around the Earth with the same speed the Earth spins.
