Vanth, officially (90482) Orcus I Vanth, is the single known natural satellite of the plutino and likely dwarf planet Orcus. (Interestingly, these varying diameter estimates don't affect the density estimate much -- the density of both bodies would still be in the neighborhood of 1.5 g/cmSo now I have a conundrum.
Here are The answer, to me, is yes.
We have created a browser extension. The new number for Vanth is larger than previously estimated, and the new number for Dysnomia is much larger. It was discovered by Mike Brown and T.-A. What they learned from looking at Orcus and Vanth with Hubble is that the two bodies have This dissimilarity in color has various implications for the origin of the Vanth-Orcus system but I'm more interested in what it means about the differences in physical properties between the two.
Here are some facts about the Orcus system that are known reasonably precisely.An orbit of only 9000 kilometers is a really really close orbit.
If Vanth and Orcus do have the same albedo, then the fact that Vanth is 2.54 magnitudes fainter than Orcus would imply that Orcus' diameter would be about 900 kilometers, and Vanth would be 3.2 times smaller, 280 kilometers (which is just a bit bigger than Saturn's moon Phoebe).But I just told you that the Hubble data suggests very different albedo for Vanth and Orcus. It doesn't matter to me how things rank -- I couldn't care less, for instance, whether Pluto is bigger than Eris or not -- but, broadly speaking, size is a critical piece of information that informs us how likely a body is to have interesting geology, and there's a pretty sharp cutoff in the exact neighborhood of Vanth's range of likely diameters, between Phoebe-sized and Miranda-sized bodies, between things that are shaped only by cratering and gravity, and things that are shaped by the consequences of internal heat needing to find some way other than conduction to get out of the middle of a solar system.Still, since we've never seen any Kuiper belt object up close -- except possibly for a couple of things that might have formed out there in the Kuiper belt but got sent closer to the Sun at some point, namely Triton and Phoebe -- it's impossible to know whether size translates into interesting geology in the same way out there as it does among the moons of the outer planets. Properties. 9,006 km. Would you like Wikipedia to always look as professional and up-to-date? Earth's moon is the fifth largest moon in the solar system. And it doesn't help that some of these systems are just plain weird.Take Orcus and Vanth. 69.1k Followers, 709 Following, 705 Posts - See Instagram photos and videos from Vanth♀️ (@vanth_inkfit) Planets similar to or like Dysnomia (moon) Only known moon of the dwarf planet Eris (the most massive known dwarf planet in the Solar System) and very probably the second-largest known moon of a dwarf planet, after Pluto I Charon. Vanth may thus be a captured Congratulations on this excellent venture… what a great idea!I use WIKI 2 every day and almost forgot how the original Wikipedia looks like. Should Vanth have an albedo of only 0.12, Vanth could be as large as 380 km with Orcus being 760 km in diameter. 90482 Orcus, provisional designation 2004 DW, is a trans-Neptunian object with a large moon, Vanth. That's one reason the next few years are going to be so exciting, with Dawn exploring big worlds Vesta and Ceres, and New Horizons exploring Pluto and Charon.
The paper says: what if Vanth's albedo is half that of Orcus? Vanth was found at 0.25 arcsec from Orcus with magnitude difference of 2.7 ± 1.0. Vanth may thus be a captured Calculated with the diameter of 442.5 km (radius 221.25 km) and assumed density of To verify, the diameter of the basketball can be measured and ratios can be used to find the size of the scale Moon, which should approximately match the diameter of a tennis ball or baseball.
