TOI-1634 c
Astrophysical Synthesis & Habitability Characterization
TOI-1634 c is a confirmed unclassified exoplanet orbiting the star TOI-1634, located approximately 115 light-years (35.27 parsecs) from the Solar System. First announced in 2022 by Multiple Observatories using the Radial Velocity detection technique (measuring periodic Doppler reflex motion in the host star's spectrum), this world is catalogued in the NASA Exoplanet Archive composite census pending further mass and radius refinement.
In its orbital architecture around TOI-1634, TOI-1634 c completes one full revolution every 103 Earth days. The orbit is modeled as circular (e = 0.00), maintaining a constant stellar distance throughout its year.
ℹ️ Thermal & Atmospheric Regime: Current photometric and spectroscopic constraints for TOI-1634 c place it outside the conservative habitable zone definition pending further atmospheric characterization.
The host star TOI-1634 is classified as a low-mass red dwarf of spectral type M2 with an effective photospheric temperature of 3,472 K, a radius of 0.45 R☉, a mass of 0.451 M☉, an estimated bolometric luminosity of 0.026 L☉. Stellar evolution modeling indicates a metallicity of [Fe/H] = 0.19 dex (metal-rich relative to the Sun). From Earth, TOI-1634 shines at apparent V-band magnitude 13.217 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere. The TOI-1634 system is a multi-planet architecture hosting 2 confirmed worlds, with TOI-1634 c sharing its stellar neighborhood alongside TOI-1634 b.
