Seus planetas
ups And d — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 3 Earth years; about −39 °C, below freezing; found in 1999 by radial velocity.
ups And c — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 240 days; about 140 °C, hotter than boiling water; found in 1999 by radial velocity.
ups And b — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 5 days; about 1,300 °C, hot enough to melt rock; found in 1996 by radial velocity.
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.
