What is the density of Saturn
William Taylor
Updated on March 27, 2026
The mean density of Saturn is 0.687 grams per cubic centimeter, making it the only planet in the solar system less dense than water. The mass of the ringed planet is 5.68 x 1026 kilograms, 95 times the mass of Earth.
Can Saturn really float on water?
Saturn is very large and is the second largest planet in the Solar System. However, it is made up mostly of gas and is less dense than water. Since it is lighter than water, it can float on water. None of the other planets in our Solar System can do this because they have a higher density than water.
Does Saturn have a high density?
Saturn has the lowest density of any planet in our solar system. Its density is so low that it would float if it was placed in water. Saturn is a large gas planet with an atmosphere composed of hydrogen and helium.
What is the density of Saturn compared to Earth?
Earth is the densest planet in the Solar System, while Saturn is the least dense. The density of Earth is 5.52 g/cm3, while the density of Saturn is 0.687 g/cm3. In other words, Earth is 8 times as dense as Saturn. Another region where Saturn and Earth are similar is gravity.Why the Saturn has less density?
Uranus and Neptune are mostly ice, and Saturn is mostly gas, so it’s less dense. Above Saturn’s mass, the gravity of the planet tends to increase its density, so Jupiter is more dense than Saturn.
What planet has 16 hours in a day?
Not long after Neptune completed its first orbit around the sun since its discovery in 1846, scientists have managed to calculate the exact length of one day on the distant gas giant planet.
What is the density and volume of Saturn?
Bibliographic EntryResult (w/surrounding text)Standardized ResultMoche, Dinah. Astronomy. New York: Wiley, 1993.”Mass of Saturn is equal to 95 times that of earth. Volume of Saturn is equal to 844 times that of Earth. Saturn has the lowest average density of all the planets”0.7 g/cm3
Can Saturn float on water NASA?
Saturn could float in water because it is mostly made of gas. … Saturn spins on its axis very fast. A day on Saturn is 10 hours and 14 minutes. The Ringed Planet is so far away from the Sun that it receives much less sunlight than we do here on Earth.What planet is the hottest?
Planetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
How do you find the density of Saturn?If you’d like to calculate the density of Saturn for yourself, grab a calculator, and then divide the mass of Saturn (5.6846×1026 kg) by its volume (8.2713×1014 cubic kilometers. This gives you a final number of 0.687 g/cubic centimeter.
Article first time published onWhich planet has most density?
Earth is the fourth smallest of the planets—though in terms of the rocky planets, it’s the largest—but it’s the most dense. Jupiter is the largest planet in the solar system, but it’s Saturn—the solar system’s second largest planet—that takes the prize for least dense.
Why is Saturn dense?
Saturn is not rigid. The large bulk of Saturn’s outer volume is filled with molecular hydrogen. The interior is something much denser – maybe metallic hydrogen and/or a rocky core. The denser materials are in the center because a gravitational interaction.
Which planet has the strongest gravity?
Jupiter has the highest amount of gravity in our solar system. Jupiter is the largest in our Solar System, meaning it also has the highest gravity. You would weigh two and a half times on Jupiter than what you would on Earth.
Why does Saturn have a much lower density than Jupiter?
Saturn is significantly less dense than Jupiter. … The reason is Jupiter’s strong gravity and its compression. Even if Jupiter attracted more amount of gas, it would remain a planet of the same size since the gas would get more compressed.
Can Saturn float in a bathtub?
Saturn is predominantly comprised of hydrogen and helium gas, giving it an overall density lower than that of liquid water. However, since the planet is not a uniform, rigid object, we can’t be sure that it would float without further experimentation.
Is Saturn the least dense planet?
Saturn’s volume is greater than 760 Earths, and it is the second most massive planet in the solar system, about 95 times Earth’s mass. The Ringed Planet is the least dense of all the planets, and is the only one less dense than water.
How is Saturn not solid?
Saturn’s surface Saturn is classified as a gas giant because it is almost completely made of gas. Its atmosphere bleeds into its “surface” with little distinction. If a spacecraft attempted to touch down on Saturn, it would never find solid ground.
How do you find the density of a planet?
When calculating the density of a planet, look up its mass and radius, the latter of which is the distance from the surface to the center. Because planets are roughly spherical, calculate the volume of a sphere using the radius. Then divide the mass by the volume of the sphere to get the density.
What is the density of Saturn in G cm3?

Do we age in space?
Flying through outer space has dramatic effects on the body, and people in space experience aging at a faster rate than people on Earth. … These studies showed that space alters gene function, function of the cell’s powerhouse (mitochondria), and the chemical balance in cells.
How long is 1 second in space?
The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).
How long is 1 hour in space?
there are no hours in space. an hour is a not too convenient unit that is 1/24th of one revolution by the earth on its axis of rotation. Earth gravity is not that strong so it should only dilate time by a little bit.
What is Earth's twin planet?
Venus is sometimes called Earth’s twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets.
Which planet has the shortest day?
Jupiter is the fastest spinning planet in our Solar System, rotating on average once in just under 10 hours. That is very fast, especially considering how large Jupiter is. This means that Jupiter has the shortest day of all the planets in the Solar System.
How much would a 100 pound person weigh on Saturn?
The surface gravity on Saturn is about 107% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 107 pounds on Saturn (assuming you could find someplace to, well, stand).
Is Saturn the only planet with a ring?
Saturn is the sixth planet from the sun. … True, it’s not the only planet with rings. Jupiter, Uranus and Neptune have rings, too. But Saturn’s rings are the biggest and brightest.
Is Saturn hot or cold?
Saturn is considerably colder than Jupiter being further from the Sun, with an average temperature of about -285 degrees F. Wind speeds on Saturn are extremely high, having been measured at slightly more than 1,000 mph, considerably higher than Jupiter.
What is the density of Saturn quizlet?
Saturn’s average density is 700 kf/m^3 – less the density of water (1000 kg/m^3). Saturn’s density is so low, because it is primarily composed of hydrogen and helium, and so it would float in water.
Which planets have densities similar to Earth?
PlanetAverage Density (gm/cm3)Required Mass for 70 cm3 (gm)Venus5.2364.0Earth5.5385.0Mars3.9273.0Jupiter1.391.0
Is Earth the 4th largest planet?
While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.
What would happen if you fell into Saturn?
The atmospheric pressure would increase to 2-4 times that of Earth’s, and you’d begin slowing down. … In the final layers of Saturn’s atmosphere, you would experience temperatures so high that you couldn’t survive. The conditions would erode your space suit and body away, just like they did to the Cassini probe.
