Why does it appear that the moon and stars move in the sky?
How do stars move (describe the movement of the stars in the night sky)?
What is similar to the motion of the stars and the sun? Is the position of stars fixed or they are in motion? Why do the stars in the night sky describe a circle if we are moving around the sun too (look at a photo of the stars taken with a long exposure)? Is the sun, and are other stars, in motion? Does position of stars change? When you compare the position of the stars in the night sky what do you notice? Why do the stars at night appear to be stationary when Earth is spinning so fast? How is the sun a star? Does the Sun actually move through the constellations? How do astronomers measure the proper motion of a star when the star moves only a few arcminutes per year? Are the stars that are visible at 7 PM the same stars that are visible at 11 PM? Does their position in the sky change over those four hours? How come the stars at the outer edge of the galaxy are rotating at the same speed as the stars towards the center? Astronomy: How does the metallicity of a star change with increasing distance from the star's core? What exactly are the tiny stars that we see in the sky at night? Are they same type of stars as our sun? Does light carry the existence of a dead star, and as that light passes in every direction and does it continuously die as it travels farther? What force holds the stars in space, i.e in other galaxies? Are all the stars in the sky, suns? Can you explain the physics of the Death Star? How many stars in the sky? How many stars in the sky? What is the red star in the sky? Do stars revolve around the sun in our solar system? How does a star die? How does the positioning of stars and planets affect our lives? Why do stars form a perfect circle when you take a long exposure picture or video? Shouldn't they be scattered all over the sky? How can I know stars in the sky easily? Does light moves? Why do stars orbit in our galaxy at the same speed? Why do outer stars in galaxies rotate so quickly? What are stars made of?
