HD 190984, also known as HIP 99496, is a star located in the southern circumpolar constellation Pavo, the peacock.
Based on parallax measurements from the Gaia spacecraft, the object is estimated to be 486 light years away from the Solar System.
[12] This is an ordinary F-type main-sequence star with a stellar classification of F8 V,[3] generating energy via hydrogen fusion at its core.
However, HD 190984 has an enlarged radius of 2.31 R☉[7] and is 1.76 magnitudes[5] brighter than the main sequence, indicating that it may instead be a subgiant evolving towards the red giant branch;[1] it radiates 5.88 times the luminosity of the Sun[8] from its photosphere.
Unlike most planetary hosts, HD 190984 has an iron abundance only 32% that of the Sun's, making it metal poor.
