Solar System 2.0 (beta)

Post date: Apr 06, 2012 8:30:41 AM

HD 10180 is a star similar to our Sun nearly 130 light years away. It has six confirmed exoplanets, as many as Kepler-11 and the only two known stellar systems with that many planets. Now Mikko Toumi (2012) suggests that the systems has nine planets, confirming one previously unconfirmed (HD 10180 b) and adding two new ones (HD 10180 i and j). The system has now two terran planets (HD 10180 b and i), one superterrans (HD 10180 j), five neptunians (HD 10180 c, d, e, f, and g), and one jovian (HD 10180 h). One neptunian (HD 10180 g) is in the habitable zone.

    Here we show the relative size and orbits of these objects. The planets are shown to scale from closest to farthest from the star. Their color correspond to the color of the orbits that are also to scale but not with the planets. A mass-radius relationship was used to estimate their size. The light blue-green zone is the habitable zone of the star. Check the STATS section for current statistics on exoplanets.
