What are the surface characteristics of Saturn?

Surface. As a gas giant, Saturn doesn’t have a true surface. The planet is mostly swirling gases and liquids deeper down. While a spacecraft would have nowhere to land on Saturn, it wouldn’t be able to fly through unscathed either.

What is special about Callisto?

Callisto has the most heavily cratered surface of any world in the solar system. There are so many craters than a new impactor would obliterate an older one. The most prominent feature on Callisto is a multi-ringed impact basin called Valhalla. There is a thin atmosphere at Callisto made mostly of carbon dioxide.

Is there gravity on Callisto?

1.236 m/s²

What is a unique characteristic of Saturn?

A unique feature of Saturn is that it is the least dense planet in the Solar System. Although Saturn may have a dense, solid core, the large gaseous outer layer of the planet makes its average density a mere 687 kg/m3. As result, Saturn is lighter than water.

What are 5 facts about Saturn?

Facts about Saturn

  • Saturn is the most distant planet that can be seen with the naked eye.
  • Saturn was known to the ancients, including the Babylonians and Far Eastern observers.
  • Saturn is the flattest planet.
  • Saturn orbits the Sun once every 29.4 Earth years.
  • Saturn’s upper atmosphere is divided into bands of clouds.

Where is Saturn in relation to the moon?

The moon and Saturn are nowhere near each other in space. The moon will be 232,800 miles (374,500 kilometers) from Earth, while Saturn is almost 3,686 times farther away, at 858 million miles (1.380 billion km).

What is the Callisto Effect?

He wrote several books and proposed a theory he called the “Callisto Effect”, which stated that evolution periodically brings about a creature so powerful and well-adapted (a “monster species”) that it triggers a mass extinction event.

Why 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. It’s unclear if the ocean could have life in it because the surface is so old.

Why is Callisto not in orbital resonance?

It is not in an orbital resonance like the three other Galilean satellites—Io, Europa, and Ganymede—and is thus not appreciably tidally heated. Callisto’s rotation is tidally locked to its orbit around Jupiter, so that the same hemisphere always faces inward.

What are 4 characteristics of Saturn?

Student Features

  • Saturn is huge.
  • You cannot stand on Saturn.
  • Its beautiful rings are not solid.
  • Some of these bits are as small as grains of sand.
  • The rings are huge but thin.
  • Other planets have rings.
  • Saturn could float in water because it is mostly made of gas.
  • It is very windy on Saturn.

Why is Saturn so special?

Adorned with thousands of beautiful ringlets, Saturn is unique 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 of hydrogen and helium.

What are the features of the moon Callisto?

Features of Callisto. This is a long series of craters arranged in a nearly straight line. This was likely caused by an object that was broken into several pieces by tidal forces before it impacted the surface. Callisto has an extremely thin atmosphere of carbon dioxide. No evidence of a magnetic field has been detected.

Why is the surface of Callisto covered in craters?

Features of Callisto. Astronomers believe this to be a result of movement in its icy surface. The entire surface of Callisto is covered with craters. The largest craters have concentric rings that look like huge cracks in the surface. These rings may have formed when water beneath the crust leaked through to the surface.

How big is the subsurface ocean on Callisto?

Structure. Callisto has an icy surface covered by craters of various shapes and sizes, including bowl-shaped craters and craters with multiple rings. Data gathered by the Galileo spacecraft indicate Callisto may have a subsurface ocean and scientists estimate it may be 155 miles (250 kilometers) below the surface.

How big is Callisto compared to the size of Jupiter?

Callisto is the outermost of the four Galilean moons of Jupiter. It orbits at a distance of approximately 1 880 000 km (26.3 times the 71 492 km radius of Jupiter itself). This is significantly larger than the orbital radius—1 070 000 km—of the next-closest Galilean satellite, Ganymede.
