Key Points:
- Astronomers have discovered a new super-Jupiter exoplanet, TIC-65910228 b, nearly five times the mass of Jupiter, orbiting a metal-rich sun-like star 864 light years away, using NASA’s TESS and follow-up observations with NGTS, HARPS, and CORALIE instruments.
- TIC-65910228 b has a radius 1.08 times that of Jupiter, a mass of 4.78 Jupiter masses, a density of 4.69 g/cm³, and orbits its star every 180.53 days at 0.7 AU, classifying it as a warm Jupiter with an estimated equilibrium temperature of 458 K.
- The planet’s atmosphere may contain molecular nitrogen
