Characteristics
2MASS J0355+11 was discovered in 2006 by Reid et al.[5]
It is radio-quiet brown dwarf, indicating an absence of stellar flares.[6] Its carbon to oxygen ratio, equals to 0.56, is similar to that of Sun's.[7]
The interstellar comet 2I/Borisov has passed 1.4 light-years (0.44 parsecs) from 2MASS J0355+11 280 thousand years before arriving to the Solar System.[8]
