Exoplanet Database

The characterization of extrasolar planets has shifted from simple detection to complex atmospheric and geological modeling. This database aggregates high-fidelity data from the Kepler, TESS, and ground-based radial velocity surveys. It is designed for researchers and students who require precise physical parameters - such as semi-major axis, eccentricity, and insolational flux - to understand the diversity of planetary formation.

Understanding a planet's potential for life requires more than just its orbital distance. We must calculate the Earth Similarity Index (ESI) and surface gravity, factors that determine atmospheric retention and tectonic activity. This tool provides a rigorous comparison engine, allowing users to simulate the gravitational environment of Super-Earths and Hot Jupiters relative to terrestrial standards. Accuracy in these comparative metrics is critical for filtering targets for future James Webb Space Telescope observations.

To determine the surface gravity of a rocky exoplanet relative to Earth, we apply Newton's Law of Universal Gravitation, scaling the result to Earth units. This metric is vital for determining the feasibility of human exploration or the potential height of topographical features.

Where M_p is the planet's mass in Earth masses (M_⊕) and R_p is the radius in Earth radii (R_⊕). Additionally, the equilibrium temperature is estimated assuming a specific Bond albedo (A) and stellar luminosity (L).
