HD 33564 is a 5th magnitude star located approximately 48 light-years away in the constellation of Camelopardalis. It is an F-type main sequence, indicating that the star is hotter and more massive than our Sun. The age of the star is only 3 Ga; despite of this, the star is only 76% the solar abundance of iron. HD 33564 is a naked eye planetary host star.
In September 2005, a massive planet was found orbiting the star surrounded by a disk. However, by next month, the disk was disproved because the infrared radiation is actually coming from the background galaxy passing very close to its star in apparent distance.
