Thnx to all, for the answer. I had a good time discussing and clearing my doubt.

>Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.
It takes the Sun 226 million years to orbit the Milky way. We started naming/documenting constellations only about 10,000 years ago
Go look up at the night sky, note where things are, then go check 24 minutes later. The Earth will have completed a greater percentage of its orbit around the sun in those 24 minutes than the sun has completed around the galactic core since humanity invented writing
Stars do move and change over time but the distances are insane relative to the speed so it takes a longgg time. The brightest star in Orion’s belt is Alnilam about 2,000 light years from Earth. To get it to move even 1 degree in the sky it’d need to cover 35 light years, to cover that since the founding of the Roman empire (27 BC) and today would require it move at 1.7% the speed of light. Basically no star is moving close to that fast except a couple oddballs that get wayyy too close to the blackhole in the core
