WASP-84
Sign in to saveWASP-84, also known as BD+02 2056, is a G-type main-sequence star away in the constellation Hydra. Its surface temperature is 5350 K and is slightly enriched in heavy elements compared to the Sun, with a metallicity Fe/H index of 0.05. It is rich in carbon and depleted of oxygen. WASP-84's age is probably older than the Sun at 8.5 billion years. The star appears to have an anomalously small radius, which can be explained by the unusually high helium fraction or by it being very young.
