Two planets of similar dimensions, orbiting their mother star on a common orbit – at least in theory, experts believed this scenario to be possible. Now, such a co-orbital pair (or in one case its components) may actually have been observed: A team led by Olga Balsalobre-Ruza from the Center for Astrobiology in Madrid, Spain, using the Atacama Large Millimeter / Submillimeter Array (Alma) radio observatory in Chile, spotted a debris cloud around a star that shares an orbit with an exoplanet. However, it is unclear whether the fragments are the building blocks of a growing planet or the remains of a destroyed world.
