I saw a satelitte moving in the night sky. Was it moving or was I?

Answer 1

You were both moving without relativity, but the satellite was moving relative to you, and you were moving relative to the satellite.

Answer 2

you were both moving

motion is meaningfull only if you define a system to mover relative to

if you are the system, then by definition you are fixed and the satelite is moving relative to you

if the satelite is defined as the basis, then it is fixed and you are moving relative to the satelite

in fact, the sun would be a good basis, in which case both you and the satelite are moving compared to the sun

and everthing mentioned so far and everything you have ever seen or heard of is moving relative to an arbitrary star in the Andromeda galaxy

Answer 3

You both were. The satellite is orbiting the Earth. You are stationary with respect to the Earth, but Earth orbits the Sun, which orbits the galactic cente and so on.

Answer 4

Both. Objects in space revolve around the earth, but the earth also revolves around the sun at the same time as it rotates on its axis.

Answer 5

Satellites move.

Answer 6

both
