TOI-3862 b

Host star: TOI-3862Discovered: 2026
TransitTransiting Exoplanet Survey Satellite (TESS)

Distance from Earth: 249.0 parsecs (812.2 light years)

Discovery Method: Transit

The transit method detects planets by measuring the periodic dimming of a star's brightness as a planet passes in front of it. NASA's Kepler and TESS missions have used this technique to discover the majority of known exoplanets. The depth of the brightness dip reveals the planet's size relative to its star, while the period between transits gives the orbital period.

Habitability Assessment

Temperature Range

1539 K is outside the range for liquid water (180-310 K).

Rocky Planet Size

5.53 Earth radii suggests a non-rocky composition.

Habitable Zone

This planet orbits outside the estimated habitable zone of its star.

Habitability assessments are rough estimates based on limited available data. True habitability depends on many additional factors including atmospheric composition, magnetic field presence, tidal locking, and stellar activity. These assessments should not be considered definitive.
