WISEA J1141−3326 (WISE J114156.67-332635.5, W1141) is a Y-dwarf, which means it is one of the coldest directly imaged astronomical objects.

[1] W1141 was discovered in 2014 from data of the Wide-field Infrared Survey Explorer and at first the spectral type was estimated to be Y0, but no spectroscopic confirmation was present at the time.

This work found it to be metal-rich, between 100 Myrs and 1 Gyr young and low-mass (3–8 MJ).

[1] It was found that this object overlaps with a background galaxy in early observations, contaminating the measured brightness.

This had led to a falsely detection of a blue color, which is attributed to the contamination.
