HR 8799 system orbit video
The young star HR 8799 hosts four giant gaseous planets (Marois et al., 2010). The following video shows 10 different epochs of post-processed high-contrast images of the HR 8799 system observed in the near-infrared over a period of 12 years, from 2009 to 2021. Data are taken using the NIRC2 instrument installed at the Keck Telescope (Mauna Kea observatory, Hawaii, USA).
