2MASS J03552337 1133437
Brown dwarf in the constellation Taurus
2MASS J03552337+1133437 (2MASS J0355+11 ) is a nearby brown dwarf of spectral type L5γ,[ 3] located in constellation Taurus at approximately 29.8 light-years from Earth.[ 4]
Characteristics
2MASS J0355+11 was discovered in 2006 by Reid et al. [ 5]
It is young, has a low surface gravity and a red spectral energy distribution compared to field brown dwarfs.[ 6] It likely belongs to the AB Doradus moving group , which is 50 Myrs old.[ 7] At this age it would have a mass of about 13 M J . Alternatively at an older age of 150 Myrs it would have a mass of about 30 M J . It has a very red color thought to be caused by photospheric dust.[ 6]
It is radio-quiet brown dwarf, indicating an absence of stellar flares .[ 8] Its carbon to oxygen ratio, equals to 0.56, is similar to that of Sun's.[ 9]
The interstellar comet 2I/Borisov passed 1.4 light-years (0.44 parsecs) from 2MASS J0355+11 280 thousand years before arriving to the Solar System.[ 10]
