DENIS-P J1058.7-1548 is a brown dwarf of spectral type L3, located in constellation Crater at approximately 17.3 parsecs or 56.5 light-years from Earth. Its spectrum was used as a standard to define the spectral class L3 back in 1997. With a surface temperature of between 1700 and 2000 K, it is cool enough for clouds to form. Variations in its brightness in visible and infrared spectra suggest it has some form of atmospheric cloud cover.
