TIC 32032563 b

Astrophysical Synthesis & Habitability Characterization

TIC 32032563 b is a confirmed sub-neptune exoplanet orbiting the star TIC 32032563, located approximately 1656.4 light-years (507.86 parsecs) from the Solar System. First announced in 2026 by Transiting Exoplanet Survey Satellite (TESS) using the Transit detection technique (producing an estimated primary transit depth of 0.1012% across the stellar disk), this world measures 3.477 Earth radii (0.31 Jupiter radii) and has a measured mass of 11.9 Earth masses. Combining its mass and radius yields a mean bulk density of 1.56 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.98 g⊕ (9.61 m/s²), and an escape velocity of 20.7 km/s.

In its orbital architecture around TIC 32032563, TIC 32032563 b completes one full revolution every 13.835 Earth days.

☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 3.477 R⊕, TIC 32032563 b exceeds the empirical ~1.8–2.2 R⊕ Fulton radius valley threshold, indicating a substantial hydrogen-helium or supercritical volatile envelope without a conventional solid terrestrial surface.

The host star TIC 32032563 is classified as a stellar host with an effective photospheric temperature of 5,568 K, a radius of 1.0019 R☉, a mass of 1.05 M☉, an estimated bolometric luminosity of 0.866 L☉. From Earth, TIC 32032563 shines at apparent V-band magnitude 13.453 (faint and requiring research-grade or CCD telescopic photometry) in the Southern celestial hemisphere.
