HR 6287
Scientific overview
HR 6287 is a star in the constellation Hercules (Herculis), lying about 270 light-years from Earth.
Class G. Yellow stars like the Sun. On the main sequence they steadily fuse hydrogen into helium. Such stars have surface temperatures around 5,200–6,000 K and appear yellow to the eye.
