Today we are gonna be talking about Y Dwarfs.
Y Dwarfs represent the coldest subset of brown dwarfs. Brown dwarfs lack the mass required for nuclear fusion of hydrogen to helium in their core. Consequently, they gradually cool off over time and transition through spectral types: M, L, T, and Y. Y dwarfs typically have temperatures ranging between 250 Kelvin and 450 Kelvin. They are faint and challenging to detect. Their atmospheres consist of methane, ammonia, and water. The first Y dwarf was discovered by NASA's Wide-field Infrared Survey Explorer (WISE) in 2011. The closest known Y dwarf is WISE 0855-0714, located approximately 7.4 light-years from Earth.
