Solar system found

A team of astronomers say they have found a solar system that includes at least five Neptune-like planets – all within the equivalent of Mars's orbit. There might be two other planets, as well, including the smallest exoplanet yet found. 

Astronomers have discovered what they claim is a vast solar system of seven planets, orbiting a sun-like star, 127 light years away from Earth.
An international team has confirmed the presence of the five planets and have tantalising evidence of two more in the planetary system which is believed to be the largest ever detected beyond the sun.
The distance of the planets from their parent star follow a regular pattern, similar to that seen in our own solar system, say the astronomers.
“We have found what is most likely the system with the most planets yet discovered. This remarkable discovery also highlights the fact that we are now entering a new era in exoplanet research: the study of complex planetary systems and not just of individual planets.
“Studies of planetary motions in the new system reveal complex gravitational interactions between the planets and give us insights into the long-term evolution of the system,” Dr Christophe Lovis, who led the European Southern Observatory scientists, was quoted by The Daily Telegraph.
The parent star, known as HD 10180, lies in the southern constellation of Hydrus 127 light years away. The astronomers patiently studied it for six years using a planet- finding instrument called the HARPS spectrograph.
