WASP-121, also known as CD-38 3220 and formally named Dilmun, is a magnitude 10.4 star located approximately away in the constellation Puppis. WASP-121 has a mass and radius similar to the Sun's. It hosts one known exoplanet. Due to the star's strongly titled rotational axis with a stellar inclination angle of 8.1°, the planet's orbit is almost polar.

WASP-121, also known as CD-38 3220 and formally named Dilmun, is a magnitude 10.4 star located approximately away in the constellation Puppis. WASP-121 has a mass and radius similar to the Sun's. It hosts one known exoplanet. Due to the star's strongly titled rotational axis with a stellar inclination angle of 8.1°, the planet's orbit is almost polar.
The star, although metal-rich in terms of overall contents of heavy elements, is depleted of carbon. The carbon to oxygen molar ratio of 0.23 for WASP-121 is well below the solar ratio of 0.55.
