description HR 2562 b Overview
HR 2562 b is a directly imaged substellar companion to the young F-type star HR 2562. It lies at a projected separation of about 20 astronomical units and has a poorly constrained mass, with published estimates spanning roughly 13 to 30 Jupiter masses. The system contains a debris disk, and the companion's mass places it near the boundary between a very massive planet and a brown dwarf, so its classification depends partly on the adopted formation definition.
help HR 2562 b FAQ
How was HR 2562 b found?
HR 2562 b was discovered by direct imaging in 2016, meaning telescopes separated its infrared light from the much brighter host star. It was not first identified from a transit or a stellar radial-velocity wobble. [NASA Exoplanet Archive](https://exoplanetarchive.ipac.caltech.edu/overview/hr%202562b)
How massive is HR 2562 b?
Published estimates span roughly 13 to 30 Jupiter masses, so the object's status lies close to the planet and brown-dwarf boundary. The wide range reflects uncertainty in the system's age and evolutionary models. [NASA Exoplanet Archive](https://exoplanetarchive.ipac.caltech.edu/overview/hr%202562b)
How far is HR 2562 b from its star?
Its projected separation is about 20 astronomical units, comparable to the distance between the Sun and Uranus. HR 2562 is a young F-type star about 34 parsecs, or roughly 111 light-years, away. [NASA Exoplanet Archive](https://exoplanetarchive.ipac.caltech.edu/overview/hr%202562b)
Why is the HR 2562 debris disk important?
HR 2562 has a circumstellar debris disk, and the companion lies near the disk's inner region. That makes the system useful for studying how a massive substellar companion can shape dust and debris around a young star. [IPAC](https://www.ipac.caltech.edu/publication/2016ApJ...829L...4K)
