Revealed as New Horizons left the Pluto system and peered back to see the world backlit by the Sun, this shot shows even more detailed layers of a photochemical smog of methane and other molecules in Pluto’s atmosphere.

And Pluto?
If Pluto has an ocean, it must retain heat inside, possibly using an insulating layer of gas that keeps the ocean in liquid form.
Pluto vs Earth’s Moon: Pluto is 2/3 rd the diameter of Earth’s moon and its mass is 1/6 th the mass of Earth’s moon. Pluto as observed by the New Horizons spacecraft, July 13, 2015.Composite of enhanced colour images of Pluto (right) and Charon (left) taken by the New Horizons spacecraft. If our own Solar System’s habitable zone is far larger than anyone thought, then it follows that astronomers should examine many more exoplanets than those close to their host stars. Here are the highlights: It has nitrogen frost and methane snow, it has snow-capped mountains forged from ice. Its largest Because of Pluto’s remoteness and small size, even the best Observations from Earth have revealed that Pluto’s brightness varies with a period of 6.3873 Earth days, which is now well established as its Compared with the planets, Pluto is also anomalous in its physical characteristics.
It receives just 1/1,600 of the sunlight that Earth gets and its surface at the equator can get as cold as −240 °C/−400 °F. Coauthor of
“Where you find liquid water you generally find life,” said Hand. New Horizons found ammonia on Pluto, which is important because it lower the temperature that ice water melts.
Round the Sun: Pluto takes 248 Earth years to revolve around the Sun. “It’s the canary in the coal mine for habitability.” This has massive implications for astrobiologists searching for life beyond Earth.
Always for free. Pluto has 'Earth-like characteristics,' study says. (One astronomical unit [AU] is the average distance from Earth to the Sun—about 150 million km [93 million miles].) "badlands" northwest of the informally named Sputnik Planum, across the al-Idrisi mountains, onto the shoreline of Pluto's "heart" feature, and just into its icy plains.

11. “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.
Amongst the rest of the planets, the worst offender is Mercury with an eccentricity of 0.2. “The images are telling us that some sort of geological processes are going on– how could that be powered?” It seems that Pluto is geologically active; it has its own heat source. Basic astronomical data.
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.
So what New Horizons uncovered at Pluto remains truly remarkable.
Plans are afoot for an orbiter.
Features crust, attributed to freezing of a subsurface ocean. The Earth is a good little planet, with an eccentricity of only 0.016.

Pluto has a radius less than half that of Mercury; it is only about two-thirds the size of Earth’s This composite image of a possible ice volcano on Pluto includes pictures About 90 miles/150 kilometers across and 2.5 miles/4 kilometers high is something that no-one expected to see on Pluto—an enormous ice volcano. Search Britannica Pluto's distance from the sun — and the distance from Earth to Pluto — changes because of the dwarf planet's odd orbit. One year ago, NASA’s New Horizons mission made history by exploring Pluto and its moons – giving humankind our first real look at this fascinating world on the frontier of our solar system. New Horizons found an enormous heart-shaped impact crater, a reservoir of solid, but soft nitrogen ice—a glacier that has polygon shapes and troughs carved into it.
By Ashley Strickland, CNN. “The data returned has forced us to re-think everything about Pluto,” said Dr. Kevin Peter Hand, Planetary Scientists & Astrobiologist at NASA’s Jet Propulsion Laboratory, to the BBC on last week’s 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.
