Its planets
2MASS J04414489+2301513 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; about −260 °C, below freezing; found in 2010 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.
