Don_DickleIn space how does one tell what direction being no fixed point? Or how does one tell up from down and so on?
Jul (they/she)You pick a point of reference. Most things use the plane of the solar system or the Milkway Galaxy and the general direction the earth’s north faces as “up”. And then angle of inclination/declination from there.
This. There is, generally, no up or down, unless you specifically choose a frame of reference. That might be the earth, the Milky Way, or your own geosynchronous satellite.
