The comet last came to perihelion on 11 June 2012, but only brightened to about apparent magnitude 20.5.[4] There were 4 recovery images of 138P on 8 August 2018 by Pan-STARRS when the comet had a magnitude of about 21.5.[2] The comet comes to perihelion on 2 May 2019. This comet should not be confused with Comet Shoemaker–Levy 9 (D/1993 F2), which crashed into Jupiter in 1994.
