Exoplanets
This page delivers no verdict; it presents claims and evidence with their sources. No theory in science is absolute. Method
For everyone
In 1995 Mayor and Queloz found the first planet orbiting a Sun-like star (51 Pegasi). In September 2025 NASA's count of confirmed exoplanets passed 6,000. Some lie in their star's habitable zone, and their atmospheres are being searched for signs of life.
For specialists
51 Pegasi b was found by the radial-velocity method from the star's wobble with a 4.23-day period. The Kepler and TESS satellites discovered thousands of planets by the transit method. JWST can study molecules in the atmospheres of temperate planets through transmission spectroscopy.
Claims
Evidence
Supporting
The radial velocity of 51 Pegasi showed a periodic variation consistent with a companion of about half Jupiter's mass.[1]
