I’m trying to get a handle on just the local stars and planets (local to us). Some apps and sites offer a grid system with us in the (0,0,0) cube, but sites that list stars and objects don’t appear to acknowledge those. Most talk about how far away things are and where they appear in the night sky, but when we look up, that’s a 2-dimensional view of the 3D galaxy. And the earth is always moving, so saying a star is in a constellation doesn’t tell me a direction from that 0,0,0 point.
I can’t quite bring all this information together. Maybe it’s just a matter of study, but even then, it seems like there is some reference material that I’m missing.
