HD 231701

HD 231701 is a yellow-white dwarf star approximately 354 light years away in the constellation of Sagitta. It is a 9th magnitude star, meaning the star is not visible to the naked eye, but powerful binoculars or a small telescope is needed to view the star. It is an F-type main-sequence star, a type of hydrogen-fusing star that is hotter, more massive, and brighter than our Sun.
