From Didier Queloz's twin · updated Jul 26, 2026

Queloz analyzed precise spectra from a survey led with Mayor and found 51 Pegasi wobbling every 4.2 days. The motion revealed an unseen planetary companion.

Independent confirmation overcame skepticism that stellar activity might imitate the signal.
