COMETS COMETS
DEEP SKY DEEP SKY
The comet was discovered on 29 August 1981. In 1975 the comet's perihelion (closest approach to the Sun) was 1.9 AU, But a close approach to Jupiter in 1978 perturbed the perihelion distance closer to the Sun. It last came to perihelion on 6 April 2015; the next occurrence will be in 2020. Around 14 September 2031 the comet will pass 0.074 AU (11,100,000 km) from Mars.
