Pluto: Verskil tussen weergawes

Op 14 Julie 2015 was die ruimtetuig ''[[New Horizons]]'' die eerste tuig wat by Pluto verbygevlieg het.<ref name="AP-20150714">{{cite news |last=Dunn |first=Marcia |title=Pluto close-up: Spacecraft makes flyby of icy, mystery world |url=http://apnews.excite.com/article/20150714/us-sci--pluto-1a20f848e7.html |date=14 Julie 2015 |work=AP News |accessdate=14 Julie 2015 }}</ref><ref name="NYT-20150713">{{cite news |last=Chang |first=Kenneth |title=A Close-Up for Pluto After Spacecraft’s 3-Billion-MileTrip |url=http://www.nytimes.com/2015/07/14/science/a-close-up-for-pluto-after-spacecrafts-3-billion-mile-trip.html |date=13 Julie 2015 |work=The New York Times |accessdate=13 Julie 2015 }}</ref><ref name="NYT-20150706-db">{{cite news |last=Overbye |first=Dennis |authorlink=Dennis Overbye |title=Reaching Pluto, and the End of an Era of Planetary Exploration |url=http://www.nytimes.com/2015/07/07/science/space/reaching-pluto-and-the-end-of-an-era-of-planetary-exploration.html |date=6 Julie 2015 |work=The New York Times |accessdate=7 Julie 2015 }}</ref> Die tuig salsou vir [[Nasa]] mates en foto's van Pluto en sy mane neem.<ref name="About New Horizons">{{cite web|title=About New Horizons|url=http://www.nasa.gov/mission_pages/newhorizons/main/#.U2VfqfldX_E|work=nasa.gov|publisher=NASA|accessdate=3 Mei 2014}}</ref><ref name="NYT-20150706">{{cite news |last=Chang |first=Kenneth |title=Almost Time for Pluto’s Close-Up |url=http://www.nytimes.com/2015/07/07/science/space/almost-time-for-plutos-close-up.html |date=6 Julie 2015 |work=The New York Times |accessdate=6 Julie 2015 }}</ref> Kommunikasie van die ''New Horizons'' af duur vier uur om die Aarde te bereik. Terwyl die tuig inligting ingesamel en van Pluto foto's geneem het, kon dit nie met die Aarde kommunikeer nie. Tot dusver is vasgestel dat Pluto 50&nbsp;km groter is as wat aanvanklik bereken is. Wetenskaplikes is verstom oor die kleur van die dwergplaneet so ver van die son af.

Pluto en sy grootste [[natuurlike satelliet]], [[Charon (maan)|Charon]], word dikwels as 'n dubbelstelsel beskou omdat die twee liggame om hul [[massamiddelpunt]] wentel en nie om mekaar nie.<ref>{{cite web |title = The mass ratio of Charon to Pluto from Hubble Space Telescope astrometry with the fine guidance sensors | journal = Icarus | volume = 164 | pages = 254-259 | author = C.B.
