Why is Callisto not fully differentiated?
Yet Callisto seems to have frozen solid before the process of differentiation was complete. The surface of Callisto is covered with impact craters, like the lunar highlands. The survival of these craters tells us that an icy object can retain impact craters on its surface.
Is Callisto a dead moon?
Callisto is a large moon orbiting Jupiter. It has an ancient, cratered surface, indicating that geological processes could be dead. However, it may also hold an underground ocean.
Can you land on Callisto?
Like the Moon, Callisto’s surface is heavily cratered. Unlike the moon, however, these craters are remarkably large. Coupled with Callisto’s high gravity, traversing and landing can be problematic.
How close is Callisto to Earth?
628.3 million km
How long is a year on Callisto?
17 days
What does it look like on Callisto?
Because the impact craters are still visible, scientists think the moon has little geologic activity—there are no active volcanoes or tectonic shifting to erode the craters. Callisto looks like it’s sprinkled with bright white dots that scientists think are the peaks of the craters capped with water ice.
What is Callisto period of rotation?
16.68902
Which planet does Callisto most closely resemble?
Size, Mass and Orbit: Much like Ganymede, it is comparable in size to Mercury – being 99% as large – but due to its mixed composition, it has less than one-third of Mercury mass. Callisto orbits Jupiter at an average distance (semi-major axis) of 1,882,700 km.
Which planet can sustain life?
Earth
Why is Io habitable?
Io is generally considered a poor candidate for life because of all the radiation Jupiter blasts it with. In addition, no organic molecules have been detected on its surface, and it has only an extremely thin atmosphere devoid of detectable water vapor.
Is there life on Europa moon?
Europa has the smoothest surface of any known solid object in the Solar System. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath the surface, which could conceivably harbor extraterrestrial life….Europa (moon)

Can you colonize a gas giant?
Possible Colonization Methods. Creating a colony on a gas giant might sound impossible. If you tried to land on a giant planet, you would only descend into hotter and denser gasses, until the pressure caused your ship to implode. They don’t have a solid surface.
Was there life on Uranus?
There’s no process inside Uranus, like volcanism on Earth, that would give life inside the planet a form of energy. Life on Uranus would have to be vastly different from anything we have here on Earth to be able to survive.
Which moon can we live on?
The strongest candidates for natural satellite habitability are currently icy satellites such as those of Jupiter and Saturn—Europa and Enceladus respectively, although if life exists in either place, it would probably be confined to subsurface habitats.
Why can’t humans live on Neptune?
To find life on Neptune, the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water. At its surface, the temperature of Neptune dips down to 55 Kelvin. That’s very cold, and there’s no way liquid water could exist.
Does Uranus have oxygen?
The planet Uranus indeed contains a significant amount of hydrogen and methane, both highly flammable gases. Simply put, there is no free oxygen on the planet Uranus.
Is Uranus a ice giant?
The cold and remote giant planets Uranus and Neptune are nicknamed the “ice giants” because their interiors are compositionally different from Jupiter and Saturn, which are richer in hydrogen and helium, and are known as the “gas giants.” The ice giants are also much smaller than their gaseous cousins, being …
What is the hottest temp on Uranus?
Temperatures inside it may reach 8,540 F (4,727 C), which sounds warm but is cooler than other planets — Jupiter’s core may reach 43,000 F (24,000 C). Simon said that temperature is a large part of the reason for Uranus’ blandness. The ice giant doesn’t have a lot of heat.
