Starting its path 9\u02da north and slightly east of Betelgeuse (Alpha (a) Orionis), the comet tracks east in October, gaining a more southeast trajectory at the month\u2019s end to position it a little over a degree south of mag. +3.3 Xi (x) Geminorum. As a handy guide to sky distance, the apparent separation of Rigel (Beta (b) Orionis) and Mintaka (Delta (d)<span> Orionis) is 9\u02da, while the gap between Xi and 30 Geminorum \u2013 the mag. +4.5 star slightly northwest of Xi \u2013 is half a degree.<\/span><\/p>\n\n<p class=\"article-full-body sans-serif\">4P\/Faye is a periodic comet with an orbital period of 7.55 years. It\u2019s a Jupiter-family comet, a class which describes comets with a period of less than 20 years and orbital inclinations less than 30\u02da. Faye\u2019s orbit takes it in as close as 1.666 AU from the Sun at perihelion and out as far as 6.026 AU at aphelion. The last perihelion occurred on 8 September of this year.<\/p>\n\n<p class=\"article-full-body sans-serif\">4P\/Faye is named after Herv\u00e9 Faye, a French astronomer who first observed the comet on 23 November 1843, with confirmation coming on the 25th. The discovery was made<span> possible because the comet was passing close to Earth at the time, making it appear bright.<\/span><\/p>\n\n<p class=\"article-full-body sans-serif\">This month, 4P\/Faye is best seen with medium to large telescopes. Smaller instruments should be able to pick it up in a dark sky. Its position north of Orion is favourable, this area of sky reaching greatest altitude in the early hours of the morning.<\/p>\n\n<p>IMAGES: PETE LAWRENCE<\/p>\n","protected":false},"excerpt":{"rendered":"<p>View Comet 4P\/Faye<\/p>\n","protected":false},"author":24,"featured_media":24828,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ub_ctt_via":"","purple_page_number":"53","purple_custom_meta_purple_page_number":"53","purple_seq_number":"1","purple_custom_meta_purple_seq_number":"1","purple_source_article":"article_53-1.xml","purple_custom_meta_purple_source_article":"article_53-1.xml","purple_source_issue":"October-2021","purple_custom_meta_purple_source_issue":"October-2021","purple_external_id":"October-2021-53-1","purple_custom_meta_purple_external_id":"October-2021-53-1","purple_issue_code":"|0000086545||","purple_custom_meta_purple_issue_code":"|0000086545||","purple_android_product":"com.im.skyatnight.197","purple_custom_meta_purple_android_product":"com.im.skyatnight.197","purple_ios_product":"com.im.skyatnight.197","purple_custom_meta_purple_ios_product":"com.im.skyatnight.197","purple_web_product":"","purple_custom_meta_purple_web_product":"","purple_publication_id":"075fab74-0a21-4201-866a-899d6c41c40c","purple_migrated":"","kt_blocks_editor_width":""},"categories":[22],"tags":[14],"featured_image_src":"https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/09\/8I244U31Q249BA1LAJQ013OO2MTI.jpg","author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/author\/importmanagerhubsprylab-com\/"},"acf":{"readingTimeMinutes":"2"},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/09\/8I244U31Q249BA1LAJQ013OO2MTI.jpg",997,731,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/09\/8I244U31Q249BA1LAJQ013OO2MTI-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/09\/8I244U31Q249BA1LAJQ013OO2MTI-300x220.jpg",300,220,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/09\/8I244U31Q249BA1LAJQ013OO2MTI-768x563.jpg",768,563,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/09\/8I244U31Q249BA1LAJQ013OO2MTI.jpg",800,587,false],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/09\/8I244U31Q249BA1LAJQ013OO2MTI.jpg",997,731,false],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/09\/8I244U31Q249BA1LAJQ013OO2MTI.jpg",997,731,false]},"uagb_author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/author\/importmanagerhubsprylab-com\/"},"uagb_comment_info":0,"uagb_excerpt":"View Comet 4P\/Faye","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/23402"}],"collection":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/users\/24"}],"replies":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/comments?post=23402"}],"version-history":[{"count":4,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/23402\/revisions"}],"predecessor-version":[{"id":24959,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/23402\/revisions\/24959"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media\/24828"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media?parent=23402"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/categories?post=23402"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/tags?post=23402"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
