Transit
Overview
TIC 147027702 b is one of the confirmed worlds in the NASA Exoplanet Archive. Recorded as discovered in 2026. The credited discovery facility is Transiting Exoplanet Survey Satellite (TESS). Its Transit evidence gives us a way to study a planet that is usually too faint to see directly.
Its recorded radius is 10.93 times Earth's radius. Size is useful for comparison, but it cannot establish surface conditions by itself.
The planet
The archive lists a mass or minimum-mass value of 346.43 Earth masses (Mass). Radius: 10.93 Earth radii.
Mass and radius constrain possible interiors; multiple compositions can fit a given set of measurements.
Orbit & year
A year here lasts 44.405 Earth days. Its recorded semi-major axis is 0.274 AU. One AU is roughly the Earth–Sun distance.
Eccentricity: 0.127. Zero describes a circular orbit; increasing values describe more elongated ellipses.

How these methods work ↗Potential habitability
The data here does not establish habitability, liquid water, or life. An appropriate atmosphere and many other conditions would be needed.
The listed equilibrium temperature is 863 K. This is an estimated energy-balance temperature, not a measured surface temperature.
Understand the habitable zone ↗What do we actually know?
The underlying light, motion or timing signal. Usually not a photograph of the planet.
Parameters derived from observations, with instrument and model uncertainty.
Our light-year conversion and browsing class are calculated from archive values.
Equilibrium temperature is an energy-balance estimate, not surface weather.
Possible composition depends on models and may not be unique.
Surface conditions and the presence of life are not established here.
Measured signals are interpreted through models. The archive’s composite table combines published values and may include calculated estimates. Values do not necessarily form one self-consistent solution.
Radius and mass can be estimated or inferred, orbital period comes from recurring observations, and size classification is calculated by this site. Atmospheric and surface conditions remain unknown unless established by specific observations.
Consult the archive for individual parameter references and uncertainty intervals before scientific use.
