HD 19275 is a 5th magnitude star in the constellation Cassiopeia, approximately 162 light years away from Earth. It is a dwarf star, like our Sun, of the spectral type A2Vnn. It therefore has a surface temperature of 7,500 to 11,000 kelvins and is many times more luminous than the Sun. The "nn" in its spectral type signifies that it has very broad spectral lines, because it rotates very fast.[1]
