What planet does Hyperion orbit?


Why does Saturn have a lot of moons?

Saturn and Jupiter have many moons for quite a few reasons, one of the main ones being that they have an absolutely immense gravitational pull. ... A few of the outer moons of our planets are captured asteroids. Phoebe, which is a moon of Saturn, is believed to have been a captured asteroid.

Why does the moon not rotate?

Gravity from Earth pulls on the closest tidal bulge, trying to keep it aligned. This creates tidal friction that slows the moon's rotation.

How deep is the deepest crater on the Moon?

Stretching 1,550 miles (2,500 kilometers) wide and 8 miles (13 km) deep, the South Pole-Aitken basin, as the tremendous hole is known to Earthlings, is the oldest and deepest crater on the moon, and one of the largest craters in the entire solar system.

Are there bottomless craters on the moon?

At approximately 8 miles deep, it isn't "bottomless," but the Aitken Basin is the deepest crater ever observed on the Moon; of course, that depth is more than offset by the enormous area of the impact site, which is approximately 1600 miles in diameter.

Are the dark spots on the moon craters?

The surface of the Moon is covered in huge dark spots, visible from Earth even with the naked eye. These patches are known as maria - a Latin word meaning 'seas'. Prof Sara Russell, a planetary scientist at the Museum, works with rock samples and high-resolution images to study the history and geology of the Moon.

What are the dark spots in the moon?

Those spots are called maria, from the Latin word for sea, because early astronomers mistakenly thought they were lunar seas (they're actually volcanic plains). The smooth and dark maria cover 17 percent of the surface of the moon. Almost all of them are visible from Earth.

Why are there still footprints on the moon?

An astronaut's footprint can last a million years on the surface of the moon. ... That's because the moon has no atmosphere. It exists in the vacuum of space where there are no gentle breezes to sweep up the dust and erase the footprints.

Can the moon be seen from everywhere on earth?

By definition, except for a couple of days per month when the moon is new and so near the sun you can't see it, the moon is visible every single day, everywhere on Earth that has clear skies—for (very roughly) half the hours of the day, and when that swathe of hours begins and ends shifts predictably from day to day.

Why does the moon always face us?

"The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth.

Is time different on the moon?

Yes, the rate of the passage of time is different on the Moon because of its orbital velocity. This would cause clocks on the Moon to run slow. But, there's also an effect because the Moon is higher up in the gravitational field of the Earth than we are, which causes clocks on the Moon to run fast.

Do you fall slower on the moon?

The Moon's surface gravity is about 1/6th as powerful or about 1.
