A bright orange dwarf star that lies 42 light years away, which is of spectral type K2.5v and has a temperature of 5000 Kelvin. It has 6 super-Earths in orbit. They each have 4.0, 6.6, 9.5, 3.5, 5.2 and 7.1 times as much mass as Earth and periods of 4.3, 9.6, 20.4, 34.6, 51.8 and 197.8 days, respectively. Dynamic studies suggest that the planets are smaller versions of Neptune, rather than larger versions of Earth. The sixth planet out from the star orbits within the habitable zone.
