It has a yellow-white hue but is too faint to be viewed with the naked eye, having an apparent visual magnitude of 7.82.
Cool spots on the surface are generating a radial-velocity signal that is modulated by the rotation period of around five days.
[4] It is radiating 1.9[1] times the luminosity of the Sun from its photosphere at an effective temperature of 6,440 K.[4] The star was given the designation "HD 221287" before being named Poerava by representatives of the Cook Islands in the IAU's 2019 NameExoWorlds contest, with the comment "Poerava is the word in the Cook Islands Maori language for a large mystical black pearl of utter beauty and perfection.
"[7] On March 5, 2007, the astronomer Dominique Naef used the HARPS spectrograph to uncover the exoplanetary companion designated HD 221287 b (among others).
[5] Using the amplitude from observations with HARPS, he calculated a minimum mass of 3.12 times that of Jupiter, making this a superjovian.
