Planets can cause the star to have a very slight wobble or shift in normal path. This is picked up by a spectrogram. Some planetary systems actually have dust clouds around the star.
Scientist know this by the color difference on the planets surface.
They are very useful to scientists because it helps them see stars and planets better
Planets orbit stars.
You will see stars/planets orbiting what looks like nothing.
No. Dwarf planets orbit stars just like planets do. Stars orbit the center of their galaxy. An object orbiting a planet would be a moon.

An astronomer.
A scientist who studies celestial bodies such as planets, stars , and galaxies.
Orbiting stars. We know of eight planets orbiting our Sun, and we know of over 300 planets orbiting other stars.
No. We know what the stars are. They are not planets. They are distant suns, many of which do have undiscovered planets.

They found stars in the sky that moved in regular patterns, and that kept coming back
i don't know! ask a scientist.
they study the stars, watch them for long periods to discover if they wobble. if they do then they have a gravitational pull on a planet
Pretty sure it was Ptolemy.
