This space wallpaper shows a three-colour image of SCR1845-6357AB generated from the SDI filter images (blue=1.575 micron, green=1.600 micron, red=1.625 micron). Since the T-dwarf fades away towards the longer wavelengths, it appears quite blue in this image. It is roughly 50 times fainter than the star and is separated from it by an angle of 1.17 arcsecond on the sky (4.5 times the Earth-Sun distance).
