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

Planetary system

In 2007, Debra Fischer used radial velocity technique and found a Jupiter-like planet orbiting at 0.55 AU around the star.
