UZ For c
Astrophysical Synthesis & Habitability Characterization
UZ For c is a confirmed gas giant exoplanet orbiting the star UZ For, located approximately 781.5 light-years (239.6 parsecs) from the Solar System. First announced in 2011 by Multiple Observatories using the Eclipse Timing Variations detection technique, this world has a minimum or true mass of 2447.2 Earth masses (7.7 M♃), while its physical transit radius has not yet been geometrically observed.
In its orbital architecture around UZ For, UZ For c completes one full revolution every 1916.25 Earth days (5.25Julian years) at a semi-major axis of 2.8 AU (corresponding to the middle-system regime between Mars at 1.52 AU and Jupiter at 5.20 AU). Its mean orbital velocity is approximately 15.9 km/s (compared to Earth's 29.8 km/s). Its moderate orbital eccentricity of e = 0.05 carries the world between 2.66 AU at periapsis and 2.94 AU at apoapsis, driving measurable seasonal insolation cycles.
ℹ️ Thermal & Atmospheric Regime: Current photometric and spectroscopic constraints for UZ For c place it outside the conservative habitable zone definition pending further atmospheric characterization.
The host star UZ For is classified as a stellar host with an effective photospheric temperature of 5,287 K, a mass of 0.7 M☉. From Earth, UZ For shines at apparent V-band magnitude 16.775 (faint and requiring research-grade or CCD telescopic photometry) in the Southern celestial hemisphere. The UZ For system is a multi-planet architecture hosting 2 confirmed worlds, with UZ For c sharing its stellar neighborhood alongside UZ For b.
