Astronomers have discovered a planetary system containing at least five planets that orbit a star much like our own Sun.

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

Researchers say it is the "richest" system of exoplanets, planets outside our own Solar System, ever found.

The BBC's Science Correspondent Pallab Ghosh reports.
