NASA’s Cassini spacecraft has revealed for the first time surface details of Saturn’s moon Hyperion, including cup-like craters filled with hydrocarbons that may indicate more widespread presence in our solar system of basic chemicals necessary for life.
Is Hyperion A moon?
Hyperion is the largest of Saturn’s irregular, nonspherical moons. Hyperion’s mean radius is 83.9 miles (135 kilometers), but since Hyperion is rather potato-shaped, its shape can be described in terms of its diameter along its three axes: 255 x 163 x 137 miles (410 x 260 x 220 kilometers, respectively).
How far is Hyperion moon from Earth?
Traveling around Saturn in an eccentric (noncircular) orbit, Hyperion keeps an average distance of 932,637 miles (1,500,934 km) from the planet.
What planet is Uranus?
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.
What is the Hyperion?
Hyperion 1. / (haɪˈpɪərɪən) / noun. Greek myth a Titan, son of Uranus and Gaea, father of Helios (sun), Selene (moon), and Eos (dawn)
How long is a day on Hyperion?
Hyperion has a chaotic orbit. The day usually lasts about five hours.
Where is Enceladus?
Enceladus is one of the major inner satellites of Saturn along with Dione, Tethys, and Mimas. It orbits at 238,000 km from Saturn’s center and 180,000 km from its cloud tops, between the orbits of Mimas and Tethys.
What is the temperature on Hyperion?
It looks like a potato-shaped sponge or a wasp nest. The impact crater walls are bright like a skating rink, while the crater floors are dull reddish color. Of course there are no lava, the average temperature on Hyperion as in many moons, is −180 degrees Celsius.
Is Hyperion habitable?
Does life exist on Hyperion? Presently, it is too far-fetched to come to such a conclusion. The presence of biomolecules is an indication that the basic chemistry needed to support life is present, and is undoubtedly a sign of the possibility, but that doesn’t mean Hyperion is necessarily habitable for organisms.
What makes Hyperion unique?
Hyperion is known for being an irregular shape – in fact, it is the largest of the moons that orbit Saturn that are considered to be irregular. The only other moon larger than this one that has an irregular shape is Neptunian moon, Proteus.
How much does Hyperion moon weigh?
Hyperion a Moon of Saturn, has Mass 5.58 x 1018 KG which is nearly 9.3411 x 10-7 times the mass of Earth and Mean Radius is 135±4 kilometer.
What are Saturn’s 3 biggest moons?
Let’s look at the eight major moons of Saturn:
Titan. Titan is the largest of Saturn’s moons and the first to be discovered. Dione. Dione is thought to be a dense rocky core surrounded by water-ice. Enceladus. Enceladus contains more than 100 geysers at its south pole. Hyperion. Iapetus. Mimas. Rhea. Tethys.
How is Uranus blue?
Uranus gets its blue-green color from methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus’ cloud tops. Methane gas absorbs the red portion of the light, resulting in a blue-green color.
What planet is green?
Physical characteristics. Uranus is blue-green in color, as a result of the methane in its mostly hydrogen-helium atmosphere.
Do all planets rotate?
The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets’ formation.
