Rich exoplanet system discovered

Astronomers have discovered a planetary system containing at least five planets that orbit a star called HD 10180, which is much like our own Sun.

The star is 127 light years away, in the southern constellation of Hydrus.

The researchers used the European Southern Observatory (Eso) to monitor light emitted from the system and identify and characterise the planets.

They say this is the "richest" system of exoplanets - planets outside our own Solar System - ever found.

Christophe Lovis from Geneva University's observatory in Switzerland was lead researcher on the study. He said that his team had probably found "the system with the most planets yet discovered".
