Beta Corvi
Scientific overview
Kraz is a star in the constellation Corvus (Corvi), lying about 145.67 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.
