Notes and Equations
... The most basic astronomical observation is that the stars “hang together” as they move across the sky in the diurnal motion. This indicates that we should define a coordinate system fixed with respect to the stars. Just like we can specify the latitude and longitude of a place on Earth, we can speci ...

For example, Proxima Centauri is the closest star to earth other than the Sun, and is 40,000,000,000,000 km from Earth. Special units are used to measure distances in space. A light y ...
