HERMES — Heuristic Exoplanet Recognition and Model Evaluation System

Built on NASA's Kepler and TESS mission data, this tool analyzes over 100 measured parameters per object to determine if a signal is a confirmed planet, candidate, or false positive.

Learn the Basics — What Is a Transit?

Repetition Interval

“When a planet passes in front of its star, it blocks some light. AI looks for this repeated dimming pattern.”
