The rectangle superimposed on the global view of Charon shows the approximate location of this close-up view.
The image was taken at approximately 6:30am EDT on 14 July 2015, about 1.5 hours before closest approach to Pluto, from a range of 49,000 miles (79,000 kilometres).
An international team of astronomers have discovered a new dwarf planet orbiting beyond Neptune. The object is roughly 435 miles in size, moving in a 700-year orbit that takes it more than 120 times further from the Sun than Earth. Designated 2015 RR245, it was found using the Canada-France-Hawaii Telescope on Maunakea, Hawaii.
In the latter part of June, Pluto is best seen low in the southern UK sky around 2am local time and reaches opposition on 7 July. The dwarf planet passes less than 1/20th of a degree south of naked-eye star pi (π) Sagittarii on 26—27 June in the deep twilight of the UK, but Southern Hemisphere observers will have the best views.
NASA’s New Horizons spacecraft took this stunning image mere minutes after closest approach on 14 July 2015. Seen here, sunlight filters through and illuminates Pluto’s complex atmospheric haze layers over portions of the nitrogen ice plains informally named Sputnik Planum, as well as mountains of the informally named Norgay Montes.
