138P/Shoemaker–Levy, also known as Shoemaker–Levy 7, is a faint Jupiter-family comet with a 7-year orbit around the Sun. During its 2012 perihelion, the comet brightened to about apparent magnitude 20.5.
There were 4 recovery images of 138P on 8 August 2018 by Pan-STARRS when the comet had a magnitude of about 21.5. The comet came to perihelion on 2 May 2019, and the next perihelion is 24 March 2026.
