Orbital Differences Between Earth and Proxima Centauri b
This data visualization compares the relative distances and speeds of Proxima B's orbit to the Earth's orbit. Proxima B rapidly orbits its sun every 11.2 days.
Proxima Centauri b is the closest exoplanet to Earth. It is only four light years away. It's star is a red dwarf that is much smaller than our Sun. However, it is much closer to its star than Earth is to the Sun. It also orbits around it's star at a much faster rate than Earth.
Earth's orbit around the sun takes 365 days to complete.
Proxima B's orbit around its star takes 11.2 Earth days to complete.
