HD 181327 is a young F-type main-sequence star located 156 light years from Earth in the constellation of Telescopium. It is part of the Beta Pictoris Moving Group. HD 181327 is surrounded by a thin debris disk which is often called a Kuiper Belt analog because it is full of icy bodies colliding within the disk. Large amounts of water ice was detected in the debris disk of HD 181327 by using the James Webb Space Telescope.
The star co-moves with Eta Telescopii. No directly imaged exoplanets were detected in a search with the Very Large Telescope.
