Star in the constellation Centaurus
HD 101930 , also known asGliese 3683 , is an orange huedstar with an orbitingexoplanet located in the southernconstellation Centaurus . It has anapparent magnitude of 8.21,[ 2] binoculars but not to thenaked eye . The system is located relatively close at a distance of 98light years [ 1] radial velocity ofkm/s [ 5] proper motion , traversing thecelestial sphere with anangular velocity of″ −1 .[ 13]
HD 101930 has astellar classification of K2 V+,[ 3] K-type main-sequence star . It has a current mass of 0.82 M ☉ [ 6] billion years old,[ 8] Sun . The object has 87% theradius of the Sun [ 7] effective temperature ofK [ 5] luminosity 43% that of theSun from itsphotosphere .[ 8] metallicity 26% above solar levels.[ 10] projected rotational velocity is similar to the Sun's, having a value ofkm/s [ 11]
A 2007 multicity survey found a co-moving companion located″ [ 14] binary star . It has a class of M0-1[ 15] mass of 0.7 M ☉ [ 14]
In 2005, the discovery of an exoplanet orbiting the star was announced. This is another discovery using theradial velocity method with theHARPS spectrograph . As theinclination of theorbital plane is unknown, only a lower bound on the mass can be determined. It has at least 30% of themass of Jupiter .[ 5]
