TOI-6041 c
Astrophysical Synthesis & Habitability Characterization
TOI-6041 c is a confirmed gas giant exoplanet orbiting the star TOI-6041, located approximately 236.4 light-years (72.47 parsecs) from the Solar System. First announced in 2025 by Multiple Observatories using the Radial Velocity detection technique (measuring periodic Doppler reflex motion in the host star's spectrum), this world measures 10.5 Earth radii (0.94 Jupiter radii) and has a measured mass of 77.9 Earth masses (0.25 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.37 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.71 g⊕ (6.96 m/s²), and an escape velocity of 30.5 km/s.
In its orbital architecture around TOI-6041, TOI-6041 c completes one full revolution every 88 Earth days at a semi-major axis of 0.3721 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 46 km/s (compared to Earth's 29.8 km/s).
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 404 K (+131°C / +268°F) and receiving 4.42 S⊕ (~6,016 W/m²), TOI-6041 c orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-6041 is classified as a solar-type yellow star of spectral type G7 with an effective photospheric temperature of 5,445 K, a radius of 0.879 R☉, a mass of 0.885 M☉, an estimated bolometric luminosity of 0.609 L☉. Stellar evolution modeling indicates an estimated stellar age of 7.9 Gyr and a metallicity of [Fe/H] = 0.104 dex (metal-rich relative to the Sun). From Earth, TOI-6041 shines at apparent V-band magnitude 9.838 (accessible to binoculars and small amateur telescopes) in the Northern celestial hemisphere. The TOI-6041 system is a multi-planet architecture hosting 2 confirmed worlds, with TOI-6041 c sharing its stellar neighborhood alongside TOI-6041 b.
Methodology: Computed using the Schulze-Makuch et al. (2011) weighted metric comparing physical interior (radius, estimated density) and surface thermal regime (escape velocity, equilibrium temperature).
