Characteristics

MASCARA-1b is a

hot Jupiter Hot Jupiters (sometimes called hot Saturns) are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter (i.e. Jupiter analogue, Jupiter analogues) but that have very short orbital periods (). The close proximity to t ...

transiting its parent

; its orbit is misaligned with the star's rotation. The planet was found unusually reflective for hot Jupiter with the measured geometric albedo of 0.171 and dayside temperature of 3062 K. Attempts to spectroscopically characterize its composition were failing as in 2022 due to relatively high planetary surface gravity resulting in compact atmosphere.
