A rare exoplanet which orbits around two stars at once - like Luke Skywalker’s home planet of Tatooine in the Star Wars universe, has been detected using a ground-based telescope by a team led by the University of Birmingham.
The planet, called Kepler-16b, has so far only been seen using the Kepler space telescope. It orbits around two stars, with the two orbits also orbiting one another, forming a binary star system. Kepler-16b is located some 245 light years from Earth and would have two sunsets if you could stand on its surface.
The 193cm telescope used in the new observation is based at the Observatoire de Haute-Provence, in France. The team was able to detect the planet using the radial velocity method, in which astronomers observe a change in the velocity of a star as a planet orbits about it.
