TYC 8998-760-1 explained

TYC 8998-760-1 is a young star, about old, located 310 light years away in the constellation of Musca, with a mass times the Sun.

Planetary system

There are two giant bodies orbiting the star. The European Southern Observatory's Very Large Telescope photographed the two bodies using its SPHERE instrument, producing the first direct image of multiple bodies orbiting a Sun-like star.[1] [2]

TYC 8998-760-1 b

TYC 8998-760-1 b is a body which has a mass 21.8 times that of Jupiter (most likely making it a brown dwarf), and a radius of . It orbits at a distance of, or slightly more than 5 times the Neptune-Sun distance.[3] [4] In July 2021, astronomers reported the detection, for the first time, of an isotope in the atmosphere of an exoplanet; more specifically, the isotope Carbon-13 (C13) was found in the atmosphere.[5] [6]

TYC 8998-760-1 c

TYC 8998-760-1 c is a body with a mass of, and orbits at, or slightly more than 11 times the Neptune-Sun distance.[7]
