[5] Analysis of the spectrum shows that the binary is probably old and has a total mass of 32+5−6 MJ for an age of 10 billion years.

If it is however young (about 1 billion years), it would be a pair of planetary-mass objects with a total mass of 8.7+1.3−1.6 MJ.

[4] WISE 0146+4234 was discovered in 2012 by J. Davy Kirkpatrick et al. from data, collected by Wide-field Infrared Survey Explorer (WISE) Earth-orbiting satellite — NASA infrared-wavelength 40 cm (16 in) space telescope, which mission lasted from December 2009 to February 2011.

In 2012 Kirkpatrick et al. published a paper in The Astrophysical Journal, where they presented discovery of seven new found by WISE brown dwarfs of spectral type Y, among which also was WISE 0146+4234.
