In-depth exploration of exoplanet habitability involves a crucial screening process
to identify a subset with the potential for sustaining life. The Habitability Index for Transiting
Exoplanets (HITE) emerges as a vital tool, quantifying a planet’s habitability by
assessing the probability of it having a solid surface and liquid water. Represented by
the symbol H, the index assigns values on a scale from 0 to 1. The closer the value to 1,
the greater the potential for habitability. H integrates parameters derived from transit
data, encompassing orbital period, transit depth, duration, surface gravity, radius, and
effective temperature of the host star. Through the Virtual Planetary Laboratory (VPL),
the calculation of H is executed for exoplanets with terrestrial mass (0.3–10 M⊕) sourced
from the Transiting Exoplanet Survey Satellite (TESS) and K2 missions. The results show
that the exoplanets with the highest H values are TOI-700 d from TESS, with a value of
0.95202. Of the 228 planets examined, around 9.21% are identified as potentially habitable.
