It crossed the celestial equator on 17 December 2015 becoming a northern hemisphere object. On 17 January 2016 the comet passed 0.72\u00a0AU (108,000,000\u00a0km; 67,000,000\u00a0mi) from Earth and was around magnitude 6[6] while located in the constellation of Ursa Major.[8]C\/2013 US10 closest Earth approach on 2016-Jan-17 05:25 UTDate & time ofclosest approachEarth distance(AU)Sun distance(AU)Velocitywrt Earth(km\/s)Velocitywrt Sun(km\/s)Uncertaintyregion(3-sigma)Reference2016-01-17 05:250.7247\u00a0AU (108.41\u00a0million\u00a0km; 67.37\u00a0million\u00a0mi; 282.0\u00a0LD)1.388\u00a0AU (207.6\u00a0million\u00a0km; 129.0\u00a0million\u00a0mi; 540\u00a0LD)59.035.8\u00b1 125 kmHorizonsC\/2013 US10 is dynamically new. It came from the Oort cloud with a loosely bound chaotic orbit that was easily perturbed by galactic tides and passing stars. Before entering the planetary region (epoch 1950), C\/2013 US10 had an orbital period of several million years.[4] After leaving the planetary region (epoch 2050), it will be on an ejection trajectory.[4] The Sun’s escape velocity at 200 AU is 2.98 km\/s[9] and the comet will be going 3.0 km\/s at 200 AU from the Sun.[10]C\/2013 US10 distance and velocity compared to the Sun with a 400 year stepsize[11]DateSun distance(AU)Velocitywrt Sun(km\/s)Uncertaintyregion(3-sigma)1615-11-15304.0\u00a0AU (45.48\u00a0billion\u00a0km; 28.26\u00a0billion\u00a0mi)2.40\u00b1 3 million kmPerihelion0.823\u00a0AU (123.1\u00a0million\u00a0km; 76.5\u00a0million\u00a0mi)46.4\u00b1 140 km2415-11-15306.9\u00a0AU (45.91\u00a0billion\u00a0km; 28.53\u00a0billion\u00a0mi)2.44\u00b1 5 million kmGallery[edit]Comet C\/2013 US10 (Warsaw, Poland; 10 January 2016, 02:51 UT+1)C\/2013 US10 imaged on 6 December 2015C\/2013 US10 imaged on 6 December 2015 (black and white)References[edit]External links[edit]li{counter-increment:listitem}.mw-parser-output .hlist ol>li::before{content:\" \"counter(listitem)\"a0 \"}.mw-parser-output .hlist dd ol>li:first-child::before,.mw-parser-output .hlist dt ol>li:first-child::before,.mw-parser-output .hlist li ol>li:first-child::before{content:\" (\"counter(listitem)\"a0 \"}]]>.navbox-abovebelow,.mw-parser-output tr+tr>.navbox-group,.mw-parser-output tr+tr>.navbox-image,.mw-parser-output tr+tr>.navbox-list{border-top:2px solid #fdfdfd}.mw-parser-output .navbox-title{background-color:#ccf}.mw-parser-output .navbox-abovebelow,.mw-parser-output .navbox-group,.mw-parser-output .navbox-subgroup .navbox-title{background-color:#ddf}.mw-parser-output .navbox-subgroup .navbox-group,.mw-parser-output .navbox-subgroup .navbox-abovebelow{background-color:#e6e6ff}.mw-parser-output .navbox-even{background-color:#f7f7f7}.mw-parser-output .navbox-odd{background-color:transparent}.mw-parser-output .navbox .hlist td dl,.mw-parser-output .navbox .hlist td ol,.mw-parser-output .navbox .hlist td ul,.mw-parser-output .navbox td.hlist dl,.mw-parser-output .navbox td.hlist ol,.mw-parser-output .navbox td.hlist ul{padding:0.125em 0}.mw-parser-output .navbox .navbar{display:block;font-size:100%}.mw-parser-output .navbox-title .navbar{float:left;text-align:left;margin-right:0.5em}]]>span,.mw-parser-output .navbar a>abbr{text-decoration:inherit}.mw-parser-output .navbar-mini abbr{font-variant:small-caps;border-bottom:none;text-decoration:none;cursor:inherit}.mw-parser-output .navbar-ct-full{font-size:114%;margin:0 7em}.mw-parser-output .navbar-ct-mini{font-size:114%;margin:0 4em}]]>  "},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki19\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki19\/c-2013-us10-catalina-wikipedia\/#breadcrumbitem","name":"C\/2013 US10 (Catalina) – Wikipedia"}}]}]
