158P/Kowal–LINEAR is a periodic comet in the Solar System that has an orbit out by Jupiter.
The Minor Planet Center had the comet coming to perihelion on 9 May 2021,[1] and JPL had the comet coming to perihelion on 12 May 2021.[2] A close approach to Jupiter on 24 July 2022 will notably lift the orbit and increase the orbital period.[5] The next perihelion passage will be in 2036 at a distance of 5.2 AU from the Sun.[4]
