Question

How do direction work in space because north,east,west and south are bonded to earth? How does a spacecraft guide itself in the unending space?

In: Physics

Answer 1

When away from the earth, stars serve as a suitable reference point. The north star is still in the same direction, even in space, and other stars become easier to use because you are no longer on the surface of a rotating sphere. Essentially, in space every star can be the north star.
