Not only is there a lot to examine in more detail, but we only really know half the story because the New Horizons flyby lasted just a few hours. Since Pluto takes 6.4 Earth days to rotate, the probe was only able to photograph one side, although “Our mission concept is to send a single spacecraft to orbit Pluto for two Earth years before breaking away to visit at least one Kuiper Belt Object (KBO) and one other KBO dwarf planet,” Either way, what was discovered at Pluto continues to change planetary science and the search for life beyond Earth. All of this was immediately obvious to the New Horizons team—and profoundly shocking.
Pluto is on average 40 times further from the Sun than Earth is—too far away from Earth to be seen with the naked eye—with sunlight taking around 5.5 hours to reach it. Pluto’s mean distance from the Sun, about 5.9 billion km (3.7 billion miles or 39.5 astronomical units), gives it an orbit larger than that of the outermost planet, Neptune.

It that’s true it would be the largest volcano discovered in the outer Solar System. The images form a strip 50 miles (80 kilometers) wide, trending (top to bottom) from the edge of Pluto’s dramatically uneven ice shell thins at Sputnik Planitia, which scientists think may contain a subsurface ocean.

“The evidence from the New Horizons mission makes it quite hard to explain what we’re seeing without invoking an ocean as an explanation,” said Hand. Pluto has 'Earth-like characteristics,' study says. And Pluto? Pluto has a radius less than half that of Mercury; it is only about two-thirds the size of Earth’s
“Where you find liquid water you generally find life,” said Hand.
It creates a sludge—a kind of lava.
Zeros of dollars.
But also take into account that Pluto is 5.5 times smaller than Earth, so someone on Pluto's surface would be 5.5 times closer to the planet's center of mass. taken by the New Horizons spacecraft’s Long Range Reconnaissance Imager (LORRI) on July 14, 2015, from a range of about 30,000 miles (48,000 kilometers), showing features as small as 1,500 feet (450 meters) across.

Pluto's distance from the sun — and the distance from Earth to Pluto — changes because of the dwarf planet's odd orbit. Chat with us in Facebook Messenger. If life exists on Pluto, it could exist almost everywhere. crust, attributed to freezing of a subsurface ocean. If Pluto could support life, so too could remote, icy exoplanets far from their host star—as well as other dwarf planets, comets, and asteroids in the outer Solar System. “It’s the canary in the coal mine for habitability.” This has massive implications for astrobiologists searching for life beyond Earth.
