It\u2019s the northernmost of a rag-tag collection of similar ringed formations which adorn this section of Fecunditatis\u2019s edge, sharing the attribute of being the largest member of the group with Colombo<\/span> 240km to the southeast; both Gutenberg and Colombo are 75km in diameter.<\/p>\n Gutenberg looks pretty battered although, with scrutiny, about three-quarters of its rim can be traced.<\/p>\n The rim is interrupted in three places. The southwest rim section has had a subtle inversion due to 15km Gutenberg A<\/span>, a fine example of a banded crater with smoothly descending inner walls leading to a 4km-diameter smooth circular floor.<\/p>\n A banded crater is one which shows alternating light and dark radial bands on its inner walls.<\/p>\n To the south is 45km Gutenberg C<\/span>, a feature that appears even older than Gutenberg.<\/p>\n Gutenberg C appears to have formed on an elevated highland section, the northern portion of which has been removed by the formation of the main Gutenberg crater.<\/p>\n The eastern rim of Gutenberg is the most damaged; 28km Gutenberg E<\/span> has completely flattened it and is itself completely flooded but also incomplete, missing a small section of its southeast and southwest rim.<\/p>\n Its lava surface is co-joined with Gutenberg\u2019s, appearing as a continuous stretch.<\/p>\n A small 3.4km craterlet is located in the southern portion of Gutenberg E\u2019s floor.<\/p>\n Internally, Gutenberg\u2019s rim descends towards the smooth, lava-filled floor.<\/p>\n The height of the rim is around 2km, the inner descent ramp varying in width from 4.1km in the southeast to 14.9km in the southwest.<\/p>\n The best-preserved section to the west, ignoring the Gutenberg A intrusion, is around 9km wide.<\/p>\n The crater\u2019s floor appears rough towards the east where peaks of mostly submerged structures can be seen.<\/p>\n Linear rilles cross the floor, entering Gutenberg\u2019s northern rim as a pair of grabens \u2013 sunken floor sections between two fault lines \u2013 crossing just north of the \u2019central mountains\u2019 then passing across the elevated floor peaks.<\/p>\n The rilles are part of Rimae Gutenberg<\/span>, a 330km set of linear rilles starting further to the northwest.<\/p>\n Approximately 2.5km wide, these features are best seen with oblique illumination when the terminator is nearby.<\/p>\n Another set of parallel rilles appears to run across the surface of Mare Fecunditatis, further to the east.<\/p>\n These belong to Rimae Goclenius<\/span>, the 55km-diameter crater Goclenius being located 114km, centre-to-centre, southeast of Gutenberg.<\/p>\n One of the Goclenius rilles can also be seen passing through its parent crater.<\/p>\n These impressive rilles are best seen with a 200mm or larger telescope.<\/p>\n This guide originally appeared in the June 2023 issue of BBC Sky at Night Magazine.<\/strong><\/em><\/p> <\/body><\/html>\n The lumps, bumps, rilles and ancient craters of this region are particularly rich to examine when the Sun is low. <\/p>\n","protected":false},"author":24,"featured_media":45396,"template":"","categories":[34],"acf":{"readingTimeMinutes":"3"},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/05\/a-guide-to-the-moons-crater-gutenberg.jpg",1200,800,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/05\/a-guide-to-the-moons-crater-gutenberg-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/05\/a-guide-to-the-moons-crater-gutenberg-300x200.jpg",300,200,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/05\/a-guide-to-the-moons-crater-gutenberg-768x512.jpg",768,512,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/05\/a-guide-to-the-moons-crater-gutenberg-1024x683.jpg",800,534,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/05\/a-guide-to-the-moons-crater-gutenberg.jpg",1200,800,false],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/05\/a-guide-to-the-moons-crater-gutenberg.jpg",1200,800,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":"The lumps, bumps, rilles and ancient craters of this region are particularly rich to examine when the Sun is low.","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/rss_feed\/45395"}],"collection":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/rss_feed"}],"about":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/types\/rss_feed"}],"author":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/users\/24"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media\/45396"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media?parent=45395"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/categories?post=45395"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\""Illustration\"](\""https:\/\/images.immediate.co.uk\/production\/volatile\/sites\/25\/2023\/05\/crater-gutenberg-location-6a67b9b.jpg?quality=90&resize=620%2C623"\" "\\"\"Illustration\\"\/")
