Gamma Camelopardalis
Scientific overview
Gamma Camelopardalis is a subgiant in the constellation Camelopardalis (Camelopardalis), lying about 358.8 light-years from Earth.
Class A. White stars with strong hydrogen lines. Many of the brightest stars in the sky are class A. Such stars have surface temperatures around 7,500–10,000 K and appear white to the eye.
