Шаблон:About

Comet C/2018 V1 (Machholz–Fujikawa–Iwamoto) is a minor body that follows a slightly hyperbolic orbit (eccentricity > 1, 16.4-sigma). It was visually discovered on 7 November 2018 by Donald Machholz using an 18.5-inch reflecting telescope[1] and it reached perihelion on 3 December 2018.

Overview

It was estimated to be between 8 and 10th magnitude from mid-November to mid-December 2018, visible in a small telescope. The value of its total (absolute magnitude of comet and coma) magnitude is 14.6 mag. It was discovered by three amateur astronomers: by an observer in Colfax, California, USA and by two observers in Japan.[2][1] The observations by three astronomers result in the name for the comet, Machholz-Fujikawa-Iwamoto.[1][3] The current orbit determination of this comet is based on 750 observations with a 37-day observation arc.[4]

Comet C/2018 V1 has a significant probability (72.6%) of having an extrasolar provenance although an origin in the Oort Cloud cannot be excluded.[5] As the present-day value of its barycentric orbital eccentricity is greater than 1, this comet is currently escaping from the Solar System, aiming for interstellar space.[5]
