414P/STEREO is a faint Jupiter-family comet with a 4.67-year orbit around the Sun. It is one of nine comets discovered by the STEREO spacecraft, and one of the first comets recovered with assistance from AI programming.[2] It last came to perihelion in September 2025 and will come to perihelion again in May 2030.[1]
