Comet Neowise was discovered on 27 March 2020 by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) space telescope mission. The comet’s nucleus has an estimated diameter of 5 km and at it’s closest (on 23 July 2020) it was 103 million km from Earth. It was visible with the naked eye during July 2020. Don’t worry if you missed it though – it will be back around again in 6,800 years time.
