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.
Also Are cryovolcanoes hot? At no point does a volcano require partially or fully molten rock, as we know it, as the magma or lava – and that, as it so happens, is where cryovolcanoes come in. … As “magma,” these liquids gather beneath the surface, rising up as they are hotter – and less dense – than their surrounding rock/ice mixtures.
Likewise How deep is the ice on Enceladus? It’s a very dark saltwater ocean. It covers the entire moon, but it’s shielded all the way around by a roughly 13 miles/20km thick ice cap, though half that at the poles. The ocean is about 25 miles/40km deep—according to NASA’s Cassini probe—which is vastly deeper than Earth’s ocean.
Is Titan habitable? Habitability. Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying “In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization.” The atmosphere contains plentiful nitrogen and methane.
Is Saturn the only planet with a ring?
Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium. Saturn is not the only planet to have rings, but none are as spectacular or as complex as Saturn’s. Saturn also has dozens of moons.
How cold is a Cryovolcano? Radioactive decay could provide the energy necessary for such activity, as cryovolcanoes can emit water mixed with ammonia, which would melt at 180 K (−95 °C) and create an extremely cold liquid that would flow out of the volcano.
Does Mars have cryovolcanoes? A few features on Mars suggest possible recent activity there. It is also very likely, perhaps probable, that active volcanoes or cryovolcanoes will be discovered on moons of icy planets in the outer portions of our solar system such as Europa, Titan, Dione, Ganymede, and Miranda.
Are there cryovolcanoes on Titan? Scientists believe the Sotra Facula region makes the best case for a cryovolcanic – or ice volcano – region on Titan. (Image credit: NASA/JPL-Caltech/University of Arizona. … SAN FRANCISCO — For the first time, scientists now have solid evidence for an ice volcano on Saturn’s moon Titan, according to a new study.
Is Enceladus habitable?
A new study published in Nature Astronomy further investigates Enceladus’ possible habitability, comparing Earth’s deep-sea plumes, where microbial life thrives, with the ones found on the icy moon, and suggesting that they may be home to Earth-like microorganisms.
How long is a day on Enceladus? One day on Enceladus is equal to 1.37 Earth days, or one day, 8 hours, and 53 minutes. This is the same amount of time it takes to complete an orbit around Saturn.
Is there life on Enceladus?
Enceladus is a small icy moon with jets or geysers of water erupting from its surface that might be connected to active hydrothermal vents at its subsurface water ocean floor, where the moon’s ocean meets the underlying rock, a prime habitat for life.
Is there life on Europa? So far, there is no evidence that life exists on Europa, but Europa has emerged as one of the most likely locations in the Solar System for potential habitability. Life could exist in its under-ice ocean, perhaps in an environment similar to Earth’s deep-ocean hydrothermal vents.
How many rings does Earth have?
If you’re talking about majestic ice rings, like we see around Saturn, Uranus or Jupiter, then no, Earth doesn’t have rings, and probably never did. If there was any ring of dust orbiting the planet, we’d see it.
What is the hottest planet?
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.
Which planet is the coldest in the solar system? However, the coldest planet is not Neptune, but Uranus — even though Uranus is a billion miles closer to the sun than Neptune. Uranus holds the record for the coldest temperature ever measured in the solar system: a very chilly minus 371 degrees Fahrenheit (minus 224 degrees Celsius), according to NASA .
Is ice a lava?
When was Enceladus discovered?
Enceladus, second nearest of the major regular moons of Saturn and the brightest of all its moons. It was discovered in 1789 by the English astronomer William Herschel and named for one of the Giants (Gigantes) of Greek mythology. Plumes of water ice spewing from the south polar region of Saturn’s moon Enceladus.
How old is Popocatepetl? According to paleomagnetic studies, the volcano is about 730,000 years old. It is cone shaped with a diameter of 25 km (16 mi) at its base, with a peak elevation of 5,450 m (17,880 ft).
Is Olympus Mons active?
Scientists posit that Olympus Mons is still a fairly young volcano from a geologic standpoint, estimating it to be only a few million years old. That being said, there’s a good chance that it’s still active and could erupt at some point in the future.
What planet is Olympus Mons? Mars Exploration: Multimedia. (largest volcano in the solar system!) The largest of the volcanoes in the Tharsis Montes region, as well as all known volcanoes in the solar system, is Olympus Mons.
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.
Can Europa support life? For Europa to be potentially habitable, it would need to have the essential chemical ingredients for the chemistry of life. … Europa’s surface is blasted by radiation from Jupiter. That’s a bad thing for life on the surface – it couldn’t survive. But the radiation may create fuel for life in an ocean below the surface.
