Stars _appear_ to move in the night sky because of Earth’s rotation (they appear to draw a circular path around the celestial poles every 24 hours, but during daylight hours none can be seen with the naked eye). In other words, in a first approximation the stars stay at a more or less fixed position on the celestial sphere but we see the entire celestial sphere rotate around us (even though it’s actually because we are on the surface of a rotating Earth).

Stars themselves _do_ move as well with respect to the celestial sphere, though, and satellites like Hipparcos have actually measured the apparent (but very slow!) movement against the background of many of the stars that aren’t too far from us.

Some paper star atlases even have “arrow indicators” on some stars to warn observers that if your atlas is too old, you need to expect to see the stars at a slightly different position.

Stars even tend to “wobble” a bit like drunkards in those paths — binary stars rotate around each other, and some stars can even be shown to have planets because they wobble a bit around the “line” which they seem to be tracing slowly across the celestial sphere.

If you‘re interested in the real movement in 3D space: most stars tend to _really_ orbit more or less around the centre of the Milky Way galaxy, but with small differences in orbit with respect to that of the Sun that may make them seem to zoom through the celestial sphere (figuratively), if you wait for VERY long.

Some of them may then even temporarily travel through the outer reaches of the solar system (the Oort cloud).

Answer 2

Explanation:

The relative positions of the stars, their configurations, the constellations, remain unchanged while the whole celestial sphere rotates daily, making the stars rise in the east and set in the west like the sun and the moon. This daily motion, of course, is only apparent; it reflects the rotation of the earth.
