This graphic presents a view of Pluto and Charon as they would appear if placed slightly above Earth’s surface and viewed from a great distance. Recent measurements obtained by New Horizons indicate ...

From Earth, about 5 billion miles away, the dwarf planet’s diameter was estimated to be 1,471 miles (2,368 km) by studying Pluto’s atmospheric haze as it passed in front of a distant star.

The size of the Solar System and the Universe is truly beyond our comprehension. When we think of the vastness of space, we ...

Pluto and Earth. Patrick Martin. 17 July 2015 ... The New Horizons spacecraft is comparatively tiny, about the size of a grand piano. Given the vast distance from the Sun, ...

Its largest moon, Charon, lacks a substantial atmosphere, and its diameter was easier to determine using ground-based telescopes. New Horizons observations of Charon confirm previous estimates of 751 ...

A new simulation of Pluto's upper atmosphere shows that it extends so far from the planet that stray molecules may be deposited on its largest moon, Charon. IE 11 is not supported.

At a press conference, New Horizons' top dog Alan Stern just announced that his team has calculated Pluto's most accurate diameter yet: about 1,473 miles from one end to the other, give or take 12 ...

For the better part of a century, we believed there were nine planets in our solar system, with Pluto being the farthest from the sun. Since the discovery of more Pluto-sized dwarf planets, that ...

It is about half the size of Pluto and about eight times less massive. The new observations put Charon's diameter at between 750 and 753 miles (1,207 and 1,212 kilometers).

Today, NASA released the first ever close-up photographs of Pluto. The images showed icy mountains and a mysterious pale patch shaped like a heart. Judy Woodruff speaks to science correspondent ...

As deep as 60 miles, or nine times the depth of Earth’s deepest seas. The estimate, based on computer modeling of the impact dynamics behind a heart-shaped region of Pluto, was published this ...

Earth To Pluto: We're Thinking It ... The National Aeronautics and Space Administration scrapped plans for a Pluto mission last year when the cost soared to $1.5 billion from $650 million.
