MASCARA-1 b: A Jupiter-Like World in a Close Orbit
MASCARA-1 is a single star located 594 light-years away, with a spectral type of A8. The star is 1 billion years old and has a mass of 1.72 solar masses, a radius of 2.1 solar radii, and a temperature of 7550 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this host.
MASCARA-1 b is a Jupiter-like planet discovered by transit in 2017. It completes one orbit in 2.15 days. Its radius is 17.9 Earth radii, larger than Earth's, which places it well above the radius threshold for its size class.
