GJ 504

system

GJ 504 (59 Virginis) — a young, Sun-like star 57 light-years away in Virgo, host to one of the few DIRECTLY IMAGED planets: GJ 504 b, a cold, low-mass giant famously inferred to glow a deep magenta PINK. Descend to explore the pink planet.

How we know

Note: A real star system, shown at its measured position in the galaxy. Its star and confirmed planets — their measured sizes and how each was found — are on the cards inside; descend to explore them. Distances follow Gaia parallax; planet data follow the NASA Exoplanet Archive.

Discovery & history

Name: A Gliese-Jahreiß designation (GJ 504); also the Flamsteed name 59 Virginis.

A nearby young Sun-like star; in 2013 the Subaru telescope's SEEDS survey photographed a faint companion in its own light — one of the coldest, lowest-mass planets ever imaged.
