1RXS J160929.1-210524 is 454 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this K7 V star; the first was found in 2008 by imaging (Gemini Observatory).
Fly there in 3D1RXS J160929.1-210524 b was photographed directly: it is one of the few exoplanets seen as its own point of light rather than inferred from its star.
Where the archive gives only a period or only an orbit size, the other is worked out from Kepler’s third law with the star’s mass.

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.
