Quick Answer: Why is saturn oblate?

Why does Saturn appear as an oblate spheroid?

With an average orbital speed of 9.69 km/s, it takes Saturn 10.759 Earth days to complete a single revolution of the Sun. Saturn’s rotation causes it to have the shape of an oblate spheroid; flattened at the poles but bulging at the equator.

Is Saturn oblate?

It is a Gas Giant planet with a rotational period of 10-11 hours (depending on latitude), and an orbital period of 29.5 years. The rapid rotation flattens Saturn at the poles by about 10%, making it the most oblate planet. Its composition is similar to that of Jupiter, being composed mostly of hydrogen and helium.

Why is Saturn the least spherical planet?

Saturn is the most oblate of the gaseous planets. This means that it is the least spherical; its equatorial diameter is larger than its polar diameter. This occurs because of its rapid rotational period: Saturn (which is about 9.5 times larger than Earth) rotates more than twice as fast as the Earth.

Why is Saturn the sixth planet?

Formation. Saturn took shape when the rest of the solar system formed about 4.5 billion years ago, when gravity pulled swirling gas and dust in to become this gas giant. About 4 billion years ago, Saturn settled into its current position in the outer solar system, where it is the sixth planet from the Sun.

What does Saturn stand for?

Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Named after the Roman god of agriculture, Saturn, its astronomical symbol represents the god’s sickle. Saturn is a gas giant with an average radius about nine times that of Earth.

What are 5 facts about Saturn?

Here are some fun facts about the Ringed Planet.

  • 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.

Is Saturn hot or cold?

With an average temperature of minus 288 degrees Fahrenheit (minus 178 degrees Celsius), Saturn is a pretty cool planet. Although there are some small differences as one travels from the equator to the poles, much of Saturn’s temperature variation is horizontal.

Who named Saturn?

Like all of the planets, Saturn is named after a character in Roman mythology. Saturn is named after the god Saturnus, the god of agriculture and harvest. Saturn is equivalent to the ancient Greek god Kronos. They decided to make the outermost planet sacred to Kronos, and the Romans did the same.

Is Saturn a failed star?

A gas giant is a giant planet composed mainly of hydrogen and helium. Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar System.

Which planet is closest to the sun?

Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

Is Earth a perfect sphere?

Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.

Is Sun a perfect sphere?

The sun is the most perfectly round natural object known in the universe, say scientists who have conducted precise measurements of its dimensions. As a spinning ball of gas, astronomers had always expected our nearest star to bulge slightly at its equator, making it very slightly flying-saucer shaped.

Does it rain diamonds on Saturn?

Lightning storms make it rain diamonds on Saturn and Jupiter

(Good luck with that.) The diamonds start out as methane gas. Powerful lightning storms on the two huge gas giants then zap it into carbon soot.

What is the number of rings on Saturn?

From far away, Saturn looks like it has seven large rings. Each large ring is named for a letter of the alphabet. The rings were named in the order they were discovered.
