First planet found in 2018, by imaging (NASA Exoplanet Archive).
Its planets
2MASS J22501512+2325342 b — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; about 1,300 °C, hot enough to melt rock; found in 2018 by imaging.
NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
