C/2015 V2 (Johnson) is a hyperbolic comet discovered on 3 November 2015 by Jess Johnson (Catalina Sky Survey) at an apparent magnitude of 17.1 using a 0.68-meter (27 in) Schmidt–Cassegrain telescope.[1][2][3][4][5] Its incoming orbit had a Semimajor Axis of 59,200 AU (0.94 light years), but will have a hyperbolic orbit after leaving the solar system, with an eccentricity of 1.0009. The comet is expected to be able to be seen with binoculars in late May 2017 in the Northern Hemisphere.[7]
