266P/Christensen is a Encke-type comet with a 6.63-year orbit around the Sun. It will next come to perihelion in December 2026. It has been suggested as the possible source of the 1977 "Wow! Signal", however this was later disproven by a follow-up study in 2020, where it was found out to be likely a maser-like flare from small hydrogen clouds in interstellar space instead.
