[3] CWISE J1055+5443 was independently discovered as a close brown dwarf in 2021 by Kirkpatrick et al. using the Wide-field Infrared Survey Explorer (WISE) and follow-up observations using the Spitzer Space Telescope.

[1] A Spitzer follow-up program found a parallax of 145.0 ± 14.7 mas, which corresponds to a close distance of around 7 parsec.

Ammonia (NH3) and methane (CH4) abundances, as well as Spitzer ch2 (4.5 μm) magnitude also match an early Y-type object.

Using the astrometry of CWISE J1055+5443 the researchers found that it has a 98.2% probability to belong to the nearby candidate moving group Crius 197, which contains 10 young stars and is about 180 ± 9 Myr old.

The membership to this group and potential young age of CWISE J1055+5443 is not certain and follow-up observations are needed to confirm this.
