Dysnomia (IPA: [dɪsˈnoʊ.mi.ə]), officially designated (136199) Eris I Dysnomia, is a moon of the dwarf planet Eris. "Dysnomia" has the same first letter as Brown's wife, Diane.[4]. In keeping with the Xena nickname that was already in use for Eris, the moon was nicknamed "Gabrielle" by its discoverers, after Xena's sidekick. In particualr, the spikes coming out of Eris, the is the only moon around. Eris are all expected patterns caused by the telescope itself, rather Astronomers now know that three of the four brightest Kuiper belt objects (KBOs) have satellites, while among the fainter members of the belt only about 10% are known to have satellites. Eris is about 2400 km in diameter, so Dysnomia is perhaps 100 km in diameter. One of these is its orbital period, thought to be about two weeks (14 days). is the discovery of the moon Observations taken on 10 September revealed a moon in orbit around Eris, it was provisionally designated S/2005 (2003 UB313) 1.

Space Telescope, and clearly showed (much to our suprise) that Dysnomia Before receiving their official names, Eris and Dysnomia were known informally as "Xena" and "Gabrielle" respectively (Gabrielle being Xena's sidekick), and Brown decided to retain that honor. Observations taken on 10 September revealed a moon in orbit around Eris, provisionally designated S/2005 (2003 UB313) 1.

In addition, both Eris and Dysnomia, representing conflict, reflect the effect their existence had in the disputation on the definition of a planet, and specifically on Pluto's status as such. This is believed to imply that collisions between large KBOs have been frequent in the past. The satellite is about 60 times fainter than Eris, and its diameter is estimated to be approximately eight times smaller. likely orbital parameters were nevertheless estimated. [2] With only a single observation, the satellite cannot yet be used to measure or constrain the mass of Eris, but important? spotty "ring" around Eris, and the slight elongation to the right of The same study suggested a wide range of potential masses for the satellite, depending on its actual density, with a system mass ratio anywhere from 37:1 to 115:1 (thus masses of approx 0.143×10 kg with a minimal 0.8g/cm density, to 0.437×10 kg for the same density as Eris itself). It was found on September 10, 2005 by Michael E. Brown and his team at the W. M. Keck Observatory. This page was last changed on 4 June 2019, at 07:32. Satellites of the largest Kuiper belt objects, https://space.fandom.com/wiki/Dysnomia?oldid=11161. We know that it is about 500 times fainter than Eris, suggesting that it is perhaps 22 times smaller in diameter than Eris. Dysnomia has an estimated diameter of 700 ± 115 km with an albedo of 0.04+0.02 −0.01. Further observations made with the Keck telescopes in August and September 2006 have led to a much better measurement of the period.

Once astronomers refine the period and the semimajor axis of the satellite's orbit (currently estimated at 36,000 km[3]), they will be able to determine the mass of the system. than from anything going around Eris. The estimate was obtained using radiometric observation by ALMA observatory in submillimeter spectral region. In keeping with the Xena nickname that was formerly in use for Eris, the moon was nicknamed "Gabrielle" by its discoverers, after the television warrior princess's sidekick. During 2005, the adaptive optics team at the Keck telescopes in Hawaii carried out observations of the four brightest Kuiper belt objects (Pluto, 2005 FY9, 2003 EL61, and Eris), using the newly commissioned laser guide star adaptive optics system.

Take your favorite fandoms with you and never miss a beat. Also, the English translation of "Dysnomia", "lawlessness," echoes Lucy Lawless, the actress famous for starring in Xena: Warrior Princess on television. It was found on September 10, 2005 by Michael E. Brown and his team at the W. M. Keck Observatory. Dysnomia is the only known moon of the dwarf planet Eris. [2] It is probably about 600 km in diameter (across),[2] although it may be up to 800 km in diameter.

These images, shown below, are so good that Impacts between bodies of the order of 1000 km across would throw off large amounts of material which would coalesce into a moon. [2] The moon was named Dysnomia[3] (from the Ancient Greek word Δυσνομία that means "lawlessness") after the daughter of the Greek goddess Eris. It was discovered in 2005 by Mike Brown and the laser guide star adaptive optics team at the W. M. Keck Observatory, and carried the provisional designation of S/2005 (2003 UB313) 1 until officially named Dysnomia[1] (from the Greek word Δυσνομία meaning "lawlessness") after the daughter of the Greek goddess Eris. It was discovered in 2005 by Mike Brown and the laser guide star adaptive optics team at the W. M. Keck Observatory, and carried the provisional designation of S/2005 (2003 UB313) 1 until officially named Dysnomia (from the Greek word Δυσνομία meaning "lawlessness") after the daughter of the Greek goddess Eris. Brown also notes that James Christy, who discovered Charon, followed the principle established with Pluto (the name of which was chosen in part because its first two letters reflected the initials of its supposed discoverer, Percival Lowell) by choosing a name which started with the same first four letters as his wife's name, Charlene. It is probably about 600 km in diameter (across), although it may be up to 800 km in diameter. The name Dysnomia (Greek Δυσνομία) was chosen due to its multiple resonances for its discoverer, Mike Brown. A similar mechanism is believed to have led to the formation of Earth's own Moon when the Earth was struck by a giant impactor early in the history of the solar system.

Dysnomia (IPA: ), officially designated (136199) Eris I Dysnomia, is a moon of the dwarf planet Eris. Telescope itself.

Dysnomia, as daughter of Eris, fits the general historically established pattern of naming moons after lesser gods associated with that for which the primary is named. Right now we are not certain how big the moon is, but we can make some guesses based on how much light it reflects. Our best images came from the Hubble During 2005, the adaptive optics team at the Keck telescopes in Hawaii carried out observations of the four brightest Kuiper belt objects (Pluto, Makemake, Haumea, and Eris), using the newly commissioned laser guide star adaptive optics system. you also can see some of the artifacts caused by the Hubble Space Space Wiki is a FANDOM Lifestyle Community. engineering team at the Keck Observatory. Why Dysnomia[1] is the only known moon of the dwarf planet Eris. from Wikipedia, the free encyclopedia Dysnomia (moon of Eris) Dysnomia, is a moon of the dwarf planet Eris. Also, Xena's character was played by actress Lucy Lawless, whereas Dysnomia is the Greek goddess of lawlessness. large
