The US space agency NASA has released a series of 10 close-ups of Pluto. A day of Pluto is equivalent to 6.4 Earth days.
What the actual detail is?
According to NASA, these images reveal many details about Pluto. The images were taken by the Long Range Reconnaissance Imager (LORRI) and the Ralph/Multispectral Visible Imaging Camera on board New Horizons spacecraft when it zoomed past the dwarf planet in an unprecedented flyby in July. A series of 10 close- photos were also taken of Pluto’s largest moon, Charon. The images also reveal the differences between the encounter hemisphere and the so-called “far side” hemisphere seen only at lower resolution.
Charon – like Pluto also rotates once every 6.4 Earth days.
