Uranus’s mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptune’s at roughly four times that of Earth. A resulting density of 1.27 g/cm3 makes Uranus the second least dense planet, after Saturn.
What is the density of Uranus compared to Earth?
Uranus’s mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptune’s at roughly four times that of Earth. A resulting density of 1.27 g/cm3 makes Uranus the second least dense planet, after Saturn.
What is the density of Uranus atmosphere?
Surface Pressure: >>1000 bars Temperature at 1 bar: 76 K (-197 C) Temperature at 0.1 bar: 53 K (-220 C) Density at 1 bar: 0.42 kg/m 3 Wind speeds: 0-250 m/s Scale height: 27.7 km Mean molecular weight: 2.64 Atmospheric composition (by volume, uncertainty in parentheses) Major: Molecular hydrogen (H 2 ) – 82.5% (3.3%); ...
What is the density of Neptune?
It is more than seventeen times as massive as Earth. The rock, ices, and gas that make up the icy giant fill a volume of 15 trillion cubic miles (62 trillion cubic kilometers), almost 58 times the volume of Earth. The density of Neptune is 1.638 grams per cubic centimeter .
Can you float on Uranus?
Uranus comes in second as the least dense planet. What this means that instead of floating, Uranus would actually sink in water . ... Even though Uranus is 14.5 times as massive as the Earth, you would only experience about 89% the force of gravity if you could stand on its surface.
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Which is the densest planet?
Mercury and Earth are the densest planets in the Solar System (Figure 13) with densities similar to the iron-rich mineral haematite. Saturn, the least dense planet in the Solar System on the other hand, has a density lower than that of water.
Does Uranus have oxygen?
Uranus is an ice giant, meaning that its chemical makeup differs from Jupiter and Saturn, with strong enrichment in elements like carbon, nitrogen, sulfur, and oxygen , mixed with an atmosphere of hydrogen and helium.
Does Uranus support life?
Uranus’ environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Who named Uranus?
It was German astronomer Johann Bode who recommended the name Uranus, a Latinized version of the Greek god of the sky, Ouranos; however, the name Uranus didn’t gain full acceptance until the mid-1800s.
Which planet rotates the fastest?
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 days of all the planets in the Solar System.
Why is Mars density so low?
The gravity of Mars is a natural phenomenon, due to the law of gravity, or gravitation, by which all things with mass around the planet Mars are brought towards it. It is weaker than Earth’s gravity due to the planet’s smaller mass .
Does it rain diamonds on Uranus?
Deep within Neptune and Uranus , it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
Why is Uranus so hot?
Why is Uranus so hot? Despite its distance from the Sun, the largest contributing factor to its frigid nature has to do with its core. Much like the other gas giants in our Solar System, the core of Uranus gives off far more heat than is absorbed from the Sun .
What is Uranus famous for?
Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system . It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
