Five planet exo-solar system discovered


Astronomers using the European Southern Observatory have found a five-planet solar system around star HD 10180. This is significant in that it’s the most planets in a single exo-solar system ever found.

The researchers said the system around HD 10180 as unique in several respects.

It has at least five “Neptune-like planets” lying within a distance equivalent to the orbit of Mars, making it more populated than our own Solar System in its inner region. And all the planets seem to have almost circular orbits.
