I mean (based on peer replies) it does come off as a funny question, but I guess if you're young enough it is a totally legitimate question! Never thought of it that way.
But yes, you have a star chart, or atlas. The North Star locates your north and everything else you can then reference from your chart.
(I'm not familiar with southern hemisphere viewing)
And after a little while you recognize the major constellations by sight, so you can orient yourself vs. the chart even if you don't see the North Star for example.
Planets are different since their relative position changes all the time, so a static chart can't tell you where they are. But there are really only four planets you can see with eyes (Mars, Venus, Jupiter, Saturn) so you learn to recognize them pretty quickly.

- jjav 1mo agoI'm not assuming, they literally asked. I am guessing on age though, mainly because for anyone who grep up when charts was the only thing that existed, this wouldn't be a question.
- voidUpdate 1mo agoI understand maps and charts. But generally, stars stay in the same place, so its easy to put them on a map. I was trying to understand how you put a planet on a map when it keeps moving around
- aragilar 1mo agoPlanets travel along the ecliptic, so they're pretty easy to map.
