UZ For b

Astrophysical Synthesis & Habitability Characterization

UZ For b 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 2002.2 Earth masses (6.3 M♃), while its physical transit radius has not yet been geometrically observed.

In its orbital architecture around UZ For, UZ For b completes one full revolution every 5840 Earth days (15.99Julian years) at a semi-major axis of 5.9 AU (a wide outer-system orbit beyond Jupiter's 5.20 AU distance in our Solar System). Its mean orbital velocity is approximately 11 km/s (compared to Earth's 29.8 km/s). With a near-circular eccentricity of e = 0.04 (ranging from 5.664 AU at periapsis to 6.136 AU at apoapsis), the planet experiences minimal orbital distance variation.

ℹ️ Thermal & Atmospheric Regime: Current photometric and spectroscopic constraints for UZ For b 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 b sharing its stellar neighborhood alongside UZ For c.
