NASA said in a press release. Just as all the planets in our solar system orbit the sun, planets that orbit other stars are called exoplanets.Before an exoplanet’s existence is "validated," it’s first "confirmed" by scientists when different observation techniques reveal features that can only be explained by a planet.
Some clues scientists look for to find and characterize exoplanets include a star’s wobble, dips in light and minuscule movements.
A planet is then "validated" using statistics – meaning how likely or unlikely it is to be a planet based on the data, NASA explained. "When ExoMiner says something is a planet, you can be sure it's a planet," added Hamed Valizadegan, ExoMiner project lead and machine learning manager with the.
