WD 1856+534 is 80.7 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this DC star; the first was found in 2020 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DWD 1856+534 b goes round its star every 33.8 hours, 63 times as often as Mercury goes round the Sun.
WD 1856+534 is one of 3 stars in its system. The position of the other 2 is not catalogued, so only WD 1856+534 and its planets are drawn.

Values are the NASA Exoplanet Archive’s composite parameters. A radius marked estimated comes from a mass–radius relation; a mass marked minimum is M sin i. Planet sizes and colours in the 3D view are renderings: none of these worlds has been photographed as more than a point of light.
