Kepler's first law says that planets have elliptical orbits. As a result, the distance between a planet and the Sun changes rhythmically as the planet moves in its orbit. In many cases, this rhythmic change is rather subtle; for example, the Earth's distance from the Sun varies between 98.3% and 101.7% of its average value. granthams alderley edge emailWebb10 apr. 2024 · CHRX 73 B is one of the smallest companion objects ever seen around a normal star beyond our Sun.
