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":73793,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[32],"tags":[52393,52408,52367,79,52366,52400,52369,52377,52381,52379,52414,52384,52410,52368,52382,52401,52389,52413,52390,52385,52407,52370,52391,52375,52376,52397,52374,52387,52380,52383,52412,52396,52405,52378,52372,52402,52411,52392,52373,52386,52388,52404,52406,52403,52399,52398,52371,52395,52409,52394],"class_list":{"0":"post-73792","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-science","8":"tag-nasa-deep-space-missions","9":"tag-nasa-space-missions","10":"tag-nasa-voyager","11":"tag-science","12":"tag-voyager-1","13":"tag-voyager-1-1977-launch","14":"tag-voyager-1-40-years","15":"tag-voyager-1-50000-degrees","16":"tag-voyager-1-communication","17":"tag-voyager-1-cosmic-rays","18":"tag-voyager-1-current-location","19":"tag-voyager-1-data","20":"tag-voyager-1-data-transmission","21":"tag-voyager-1-deep-space","22":"tag-voyager-1-deep-space-network","23":"tag-voyager-1-discoveries","24":"tag-voyager-1-distance","25":"tag-voyager-1-distance-from-earth","26":"tag-voyager-1-electricity","27":"tag-voyager-1-engineering","28":"tag-voyager-1-facts","29":"tag-voyager-1-firewall","30":"tag-voyager-1-heat","31":"tag-voyager-1-heliopause","32":"tag-voyager-1-high-temperature","33":"tag-voyager-1-instruments","34":"tag-voyager-1-interstellar-space","35":"tag-voyager-1-longevity","36":"tag-voyager-1-magnetic-fields","37":"tag-voyager-1-mission","38":"tag-voyager-1-mission-status","39":"tag-voyager-1-news","40":"tag-voyager-1-outer-solar-system","41":"tag-voyager-1-plasma-waves","42":"tag-voyager-1-power-source","43":"tag-voyager-1-radiation","44":"tag-voyager-1-radio-waves","45":"tag-voyager-1-radioactive-power","46":"tag-voyager-1-rtg","47":"tag-voyager-1-shielding","48":"tag-voyager-1-signal","49":"tag-voyager-1-signal-strength","50":"tag-voyager-1-space-exploration","51":"tag-voyager-1-space-science","52":"tag-voyager-1-space-technology","53":"tag-voyager-1-survival","54":"tag-voyager-1-technology","55":"tag-voyager-1-update-2025","56":"tag-voyager-1-updates","57":"tag-voyager-spacecraft"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/73792","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=73792"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/73792\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/73793"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=73792"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=73792"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=73792"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
