WISE 0226−0211 (also known as WISEPA J022623.98−021142.8) is a brown dwarf binary with a combined spectral type of T7.

[4] Its individual components have a spectral type that is as of now somewhat uncertain at T8-T8.5 for the primary and T9.5-Y0 for the secondary.

[2] The object was first discovered in 2011 with the Wide-field Infrared Survey Explorer and follow-up observations with Keck revealed a spectral type of T7.

[4] In 2019 the same team showed that the object is a common proper motion binary with a separation of 2.1 arcseconds from Spitzer images and one H-band Keck image (acquired by David Ciardi).

The absolute magnitudes on the other hand suggest spectral types of about T8-T8.5 for the primary and about T9.5-Y0 for the secondary.
