The presence of CH 4 ice on Pluto implies that Pluto may have a substantial atmosphere consisting of heavy gases. Without such an atmosphere, sublimation of the CH 4 ice would be so rapid on a cosmogonic time scale that either such an atmosphere would soon develop through the exposure of ...
biological processes below Pluto’s surface. Complex layers of organic haze; water ice mountains from some unknown geologic process; possible organics on the surface; and a liquid water ocean underneath — all of these features point to a world with much more vibrancy than scientists have long ...
Does Jupiter have an atmosphere? How are craters formed by asteroids? Are volcanoes present throughout the terrestrial planets? When were most craters formed on the terrestrial planets? Is Saturn an inner or outer planet? Are there volcanoes on Pluto? Do asteroids come from the Kuiper belt? Is...
Europa's surface consists of a layer of water surrounding the mantle which is thought to be 100 kilometers thick. The uppermost section is solid ice while the bottom is believed to be liquid water, which is made warm due to heat energy and tidal flexing. If true, then it is possible th...
Dwarf planet Pluto, on the other hand, has a fairly squashed orbit.Mercury, the closest planet to the sun, has the most eccentric orbit, with the difference between the distance at perihelion and aphelion being 0.17 AU. That is quite a lot for Mercury, which orbits on average at only 0.3...
Does the asteroid belt have ice in it? Does NASA route around the asteroid belt? Did Deep Space 1 go to the asteroid belt? Is the asteroid belt shrinking? Is the asteroid belt continuous? Are any icy bodies in the asteroid belt?

“planet”. Pluto has many features that they considered to be a dwarf planet like: its large distance from the sun, that it doesn't have its own orbit, its temperature is extremely cold, all these facts are the reason why many people are still debating pluto's status. Pluto was found...
Pluto, a white dwarf, and its moon Charon have a somewhat similar size; which could be comparable to the Earth-Moon system. There are many other large moons that orbit gas giants, but those are thought to have formed rather differently. ...
Adorned with thousands of beautiful ringlets, Saturn isunique among the planets. It is not the only planet to have rings – made of chunks of ice and rock – but none are as spectacular or as complicated as Saturn's. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly ...
