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.

Planetary system[edit]

In 2007, the N2K Consortium used the radial velocity technique to discover a Jupiter-like planet orbiting at 0.55 AU around the star.[1]
