Is Thebe a moon of Jupiter?

Thebe is the planet’s seventh largest moon, with a mean radius of about 49 km. At a distance of about 138 thousand miles (222 thousand kilometers) from Jupiter, Thebe whips once around the planet in a little over 16 hours.

What is special about Jupiter’s moon Callisto?

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.

What is the surface of Thebe like?

It was discovered by the Galileo spacecraft. It is named for Zethus (Ζῆθος), the husband of the nymph Thebe in Greek mythology. The surface of Thebe is dark and appears to be reddish in color.

Is Jupiter’s moon Callisto habitable?

Callisto has a very thin atmosphere, is thought to contain an ocean, and is therefore another possible contender for life beyond Earth. However, its distance from Jupiter means it doesn’t experience such a strong gravitational pull, so it’s not as geologically active as the other Galilean moons of Io and Europa.

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 we live on Callisto?

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.

Is there oxygen on Callisto?

Scientists announced in 1999 that the Galileo spacecraft detected a very thin carbon dioxide exosphere—an extremely thin atmosphere—on Callisto during its observations in 1997. More recent research indicates Callisto also has oxygen and hydrogen in its exosphere.

How many moons does Earth have 2021?

one moon
The simple answer is that Earth has only one moon, which we call “the moon”. It is the largest and brightest object in the night sky, and the only solar system body besides Earth that humans have visited in our space exploration efforts. The more complex answer is that the number of moons has varied over time.

What is the moon of Jupiter called?

Moon of Jupiter: Thebe. Thebe is a small, red, irregular-shaped moon of the planet Jupiter. Dust ejected from it’s surface formed the Thebe Gossamer Ring around Jupiter. These characteristics make it similar to the moon Elara. Its surface has giant craters and high mountains that are comparable in size to the moon itself. For a listing…

How far away is Thebe from Jupiter?

At a distance of about 138 thousand miles (222 thousand kilometers) from Jupiter, Thebe whips once around the planet in a little over 16 hours. The satellite originally called S/1979 J2 was ultimately named “Thebe,” a name associated with Jupiter — or his Greek equivalent, Zeus — in a variety of ways in different myths.

What is the name of the inner moon Thebe?

Along with its sister inner moon, Metis, Thebe was exempted from the International Astronomical Union’s requirement that prograde satellites (not counting the Galilean moons) receive names ending in “a.”

What is the largest crater on Jupiter’s moon Thebe?

Zethus Crater is the largest (diameter about 40 km) crater on and the only named surface feature of Jupiter’s moon Thebe. There are several bright spots at the rim of this crater. It is located on the far side of Thebe, facing away from Jupiter. It was discovered by the Galileo spacecraft.
