Key numbers used<\/p>\n
Voyager 1 speed \u2248 17 km\/s (typical quoted value).<\/p>\n
1 astronomical unit (AU) = 149,597,870.7 km.<\/p>\n
1 year \u2248 365.25 days and 1 day = 86,400 seconds.<\/p>\n
Convert Voyager speed to AU per year (digit-by-digit)<\/p>\n
Seconds per year = 86,400 \u00d7 365.25 = 31,557,600 s.<\/p>\n
Distance per year = 17 km\/s \u00d7 31,557,600 s = 536,479,200 km\/year.<\/p>\n
Convert to AU: 536,479,200 km \u00f7 149,597,870.7 km\/AU \u2248 3.586 AU\/year.<\/p>\n
So Voyager 1 travels about 3.6 AU per year.<\/p>\n
Now the times for different Oort Cloud radii<\/p>\n
(We divide distance in AU by 3.586 AU\/year to get years.)<\/p>\n
If the feature is at 1,000 AU:
Time = 1,000 \u00f7 3.586 \u2248 279 years.
(This is roughly where a few sources place an inner Oort-like region in some estimates \u2014 hence the ~300-year figure.)<\/p>\n
If the inner Oort Cloud (Hills cloud) is at 2,000 AU:
Time = 2,000 \u00f7 3.586 \u2248 558 years.<\/p>\n
If the outer edge is at 100,000 AU:
Time = 100,000 \u00f7 3.586 \u2248 27,900 years (\u2248 28,000 years).
Many popular summaries round that to ~30,000 years, which is the figure you saw earlier for Voyager passing beyond the outer edge of the Oort Cloud.<\/p>\n","protected":false},"excerpt":{"rendered":"Key numbers used Voyager 1 speed \u2248 17 km\/s (typical quoted value). 1 astronomical unit (AU) = 149,597,870.7…\n","protected":false},"author":2,"featured_media":58218,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[31639,31654,31613,90,416,56,54,55,31612,31646,31615,31623,31627,31625,31660,31630,31656,31614,31628,31647,31635,31659,31636,31631,31653,31616,31637,31621,31622,31643,31620,31633,31626,31629,31658,31642,31651,31624,31618,31648,31657,31638,31619,31632,31634,31650,31652,31649,31645,31644,31617,31641,31655,31640],"class_list":["post-58217","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-nasa-deep-space-missions","tag-nasa-space-missions","tag-nasa-voyager","tag-science","tag-space","tag-uk","tag-united-kingdom","tag-unitedkingdom","tag-voyager-1","tag-voyager-1-1977-launch","tag-voyager-1-40-years","tag-voyager-1-50000-degrees","tag-voyager-1-communication","tag-voyager-1-cosmic-rays","tag-voyager-1-current-location","tag-voyager-1-data","tag-voyager-1-data-transmission","tag-voyager-1-deep-space","tag-voyager-1-deep-space-network","tag-voyager-1-discoveries","tag-voyager-1-distance","tag-voyager-1-distance-from-earth","tag-voyager-1-electricity","tag-voyager-1-engineering","tag-voyager-1-facts","tag-voyager-1-firewall","tag-voyager-1-heat","tag-voyager-1-heliopause","tag-voyager-1-high-temperature","tag-voyager-1-instruments","tag-voyager-1-interstellar-space","tag-voyager-1-longevity","tag-voyager-1-magnetic-fields","tag-voyager-1-mission","tag-voyager-1-mission-status","tag-voyager-1-news","tag-voyager-1-outer-solar-system","tag-voyager-1-plasma-waves","tag-voyager-1-power-source","tag-voyager-1-radiation","tag-voyager-1-radio-waves","tag-voyager-1-radioactive-power","tag-voyager-1-rtg","tag-voyager-1-shielding","tag-voyager-1-signal","tag-voyager-1-signal-strength","tag-voyager-1-space-exploration","tag-voyager-1-space-science","tag-voyager-1-space-technology","tag-voyager-1-survival","tag-voyager-1-technology","tag-voyager-1-update-2025","tag-voyager-1-updates","tag-voyager-spacecraft"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/58217","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=58217"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/58217\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/58218"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=58217"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=58217"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=58217"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
