HD 4208 is an 8th magnitude star located approximately 106 light years away[1] in the constellation of Sculptor. Its spectral type is G5V. It is a yellow dwarf similar to our Sun, only slightly cooler and dimmer. It is not visible to the unaided eye, but with binoculars or small telescope it should be an easy target.

In 2001, a planet was discovered orbiting the star.[2]
