In the early days, looking for wobbly stars may have been the best way for the ancient Coruscanti to find exoplanets. At least, that’s how it’s done on Earth. Thousands have been discovered in our neighborhood of the Galaxy. Planet hunters look for twitchy stars out to about 160 light-years from Earth. And, like all stars with planets, our Sun wobbles, too. The combined gravity of the planets is what causes the Sun’s wobble, especially mighty Jupiter, which is bigger than the other planets put together.
