HD 97658
HD 97658 is a star 70 light years away in the constellation of Leo. The star is slightly too dim to be seen with the naked eye, though almost any additional equipment will allow it to be seen. The star itself is a metal-poor early K-dwarf that is somewhat older than the sun.
Planetary system.
On November 1, 2010, a super-earth was announced orbiting the star along with Gliese 785 b as part of the NASA-UC Eta-Earth program
. The planet orbits in just under 9.5 days and was originally thought to have a minimum mass of 8.2 ± 1.2 M. Spurred by the possibility of transits, additional data was acquired for less than a year which found a lower mass for the star and hence reduced the minimum mass of the planet to 6.4 ± 0.7 M, and improved certainty on the time of possible transit. Transits of the planet were apparently detected and announced on September 12, 2011; this would make HD 97658 the second-to-brightest star with
