What is special about the Callisto moon?

Callisto is Jupiter’s second largest moon and the third largest moon in our solar system. Its surface is the most heavily cratered of any object in our solar system. Images of Callisto captured by passing spacecraft show bright white spots standing out against darker regions.

Can we live on Callisto moon?

As a result, humans could live on the surface of Callisto with just a sufficiently strong radiation attenuating glass between them and the remaining radiation from its host planet. In addition to this relative safety from radiation, this moon is composed of around 40% water.

Can humans survive Callisto?

Potential for Life Callisto is on the list of possible places where life could exist in our solar system beyond Earth.

Why is Callisto so colorful?

Of Jupiter’s four largest moons, Callisto orbits farthest from the giant planet. Callisto’s surface is uniformly cratered but is not uniform in color or brightness. Scientists believe the brighter areas are mainly ice and the darker areas are highly eroded, ice-poor material.

Which moon is the oldest?

The surface of Callisto is the oldest and most heavily cratered in the Solar System….Callisto (moon)

Discovery
Eccentricity	0.0074
Orbital period (sidereal)	16.6890184 d
Average orbital speed	8.204 km/s

Has NASA landed on Callisto?

NASA’s Galileo spacecraft made 12 targeted encounters with Callisto from 1996 to 2001. It flew within 686 miles (1,104 km) of Callisto’s surface, the closest any spacecraft has ever come to Callisto.

What is the safest planet?

Besides Earth, Mars would be the easiest planet to live on. Mars has liquid water, a habitable temperature and a bit of an atmosphere that can help protect humans from cosmic and solar radiation. The gravity of Mars is 38% that of the Earth.

What is a dead moon?

Updated on 02/04/18. Also known as the “dead” moon, this is the time when there is no solar reflection, leaving the lunar face in darkness. The dark lasts about three days before the new crescent appears.

Does Jupiter have 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.

Which moon is most habitable?

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.

Which is the most habitable planet after Earth?

Kepler-452b Kepler-452 is very similar to our sun, and the exoplanet orbits in the habitable zone. At 1.6 times the size of Earth, Kepler-452b has a “better than even chance” of being rocky, its discoverers have said. Kepler-452b resides 1,400 light-years from Earth.

Why is there no life on Jupiter?

Jupiter’s environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.

Is Callisto a human?

In Greek mythology, Callisto or Kallisto (/kəˈlɪstoʊ/; Ancient Greek: Καλλιστώ [kallistɔ̌ː]) was a nymph, or the daughter of King Lycaon; the myth varies in such details. She was believed to be one of the followers of Artemis (Diana for the Romans) who attracted Zeus. Many versions of Callisto’s story survive.

What was Callisto named after?

Callisto, also called Jupiter IV, outermost of the four large moons (Galilean satellites) discovered around Jupiter by the Italian astronomer Galileo in 1610. It was probably also discovered independently that same year by the German astronomer Simon Marius, who named it after Callisto of Greek mythology.

How long is a day on Callisto?

Callisto is tidally locked into orbit by Jupiter’s orbit, which means the same face (hemisphere) is always pointing toward Jupiter. Callisto orbital period is 16.7 Earth days and will have travelled over 7 million miles to orbit Jupiter.

What are 3 interesting facts about Callisto?

Basic facts Age: Callisto is about 4.5 billion years old, about the same age as Jupiter. It is the most heavily cratered object in the solar system, according to NASA. There is hardly any geologic activity on its surface. The surface has not changed much since initial impacts molded its surface 4 billion years ago.

Is Callisto the brightest moon?

Callisto is 628,300,000 km from Earth, through a telescope it is brighter in our sky than our own Moon. Callisto is brighter because its surface is made of a thick layer of ice which reflects sunlight more than our Moon. Callisto is bigger than the planet Pluto but only has one third its mass.

What is the moon Callisto made of?

The average density of Callisto, at 1.83 g/cm3, suggests a composition of approximately equal parts of rocky material and water ice, with some additional volatile ices such as ammonia. Ice is believed to constitute 49-55% of the moon, with the rock component likely made up of chondrites, silicates and iron oxide.

What is the ultimate fate of Callisto?

Callisto was then killed during the chase by Artemis, who, owing to the machinations of the jealous Hera, mistook Callisto for a real bear.
