NASA Discovers Extraordinary New Planetary System

Kepler-11 vs Solar system size comparison

Last week Nasa announced the discovery of a six world planetary system, Kepler-11,  2,000 light years distant from Earth.  The fullest and most compact extra-solar system discovered so far. This chart published on Nasa’s Astronomy Picture of the Day site compares the orbitals with our own solar system.

The Kepler-11 planetary system is amazing,” said Jack Lissauer, a planetary scientist and a Kepler science team member at NASA’s Ames Research Center, Moffett Field, Calif. “It’s amazingly compact, it’s amazingly flat, there’s an amazingly large number of big planets orbiting close to their star – we didn’t know such systems could even exist.
