.C\/2022 E3 (ZTF) \u00e4r en l\u00e5ngperiodisk komet uppt\u00e4ckt den 2 mars 2022 vid Zwicky Transient Facility (ZTF), Palomar Observatory. Den hade vid uppt\u00e4ckten magnitud 17,3 med ett avst\u00e5nd p\u00e5 4,3 AU fr\u00e5n solen. Perihelium kommer enligt ber\u00e4kningar att passeras den 12 januari 2023, d\u00e5 med ett avst\u00e5nd p\u00e5 1,11 AU till solen och 0,3 AU fr\u00e5n jorden. Man tror att magnituden som b\u00e4st kommer upp till omkring 4-5. Runt perihelium kommer kometen dessutom att ligga i n\u00e4rheten av norra himmelspolen och blir s\u00e5ledes v\u00e4l synlig hela natten fr\u00e5n v\u00e5ra nordliga breddgrader. F\u00f6r n\u00e4rvarande ligger den dock ganska l\u00e5gt i v\u00e4ster tidigt p\u00e5 kv\u00e4llen vid stj\u00e4rnbilden Norra kronan och har magnitud cirka 11.<\/p>\n<\/div>\n\n\n\n
