TIC 88692598 b
Astrophysical Synthesis & Habitability Characterization
TIC 88692598 b is a confirmed super-earth exoplanet orbiting the star TIC 88692598, located approximately 239.8 light-years (73.53 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 0.0974% across the stellar disk), this world measures 1.813 Earth radii and has a measured mass of 3.94 Earth masses. Combining its mass and radius yields a mean bulk density of 3.65 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 1.2 g⊕ (11.77 m/s²), and an escape velocity of 16.5 km/s.
In its orbital architecture around TIC 88692598, TIC 88692598 b completes one full revolution every 2.649 Earth days.
ℹ️ Thermal & Atmospheric Regime: Current photometric and spectroscopic constraints for TIC 88692598 b place it outside the conservative habitable zone definition pending further atmospheric characterization.
The host star TIC 88692598 is classified as a stellar host with an effective photospheric temperature of 3,483 K, a radius of 0.5325 R☉, a mass of 0.5292 M☉, an estimated bolometric luminosity of 0.037 L☉. From Earth, TIC 88692598 shines at apparent V-band magnitude 13.953 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere.
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).
