HIP 65426 b
HIP 65426 b is a super Jupiter exoplanet orbiting the star HIP 65426. It was discovered on 6 July 2017 by the SPHERE consortium using the Spectro-Polarimetric High-Contrast Exoplanet Research (SPHERE) instrument belonging to the European Southern Observatory (ESO). It is 385 light-years from Earth. It is the first planet discovered by ESO's SPHERE instrument. Overview. The star HIP 65426 b is orbiting lies in the constellation Centaurus. It is around 14 million years old. However, it doesn't have a debris disk, despite its young age, causing it to not fit current  models for planetary formation. It is around 92 AU from its parent star, with a possible dusty atmosphere. It was discovered as part of the SHINE program, which aimed to find planetary systems around 600 new stars. It was among the first objects to be imaged in 2022 by the James Webb Space Telescope. Planetary atmosphere. The spectrum taken in 2020 has indicated that HIP 65426 b is carbon-poor and oxygen-rich compared to Solar System gas giants.
