The discoveries were announced on 31 October 2005, after confirmation by precovering archival Hubble images of Pluto from 2002. Animation of the chaotic spin of Pluto’s moon Nix - YouTube [7], Early research appeared to show that Nix was reddish like Pluto and unlike the other moons,[1] but more recent reports have been that it is grey like the remaining moons.[4]. [8] Images of Nix from the New Horizons spacecraft show a large reddish area approximately 18 km (11 mi) across, which could explain the two conflicting measurements of Nix's surface color. [10][11] At the time of New Horizon's flyby, Nix was rotating with a period of 43.9 hours retrograde to Pluto's equator with an inclination of 132 degrees — in other words it is rotating "backwards" in relation to its orbit around Pluto. Il analyse également les commentaires pour vérifier leur fiabilité. Nix is a non-spherical moon of Pluto.It was found along with Hydra in June 2005 by the Hubble Space Telescope Pluto Companion Search Team, composed of Hal A. Weaver, S. Alan Stern, Max J. Mutchler, Andrew J. Steffl, Marc W. Buie, William J. Merline, John R. Spencer, Eliot F. Young, and Leslie A.
[20] The chaotic tumbling of Nix is also strengthened by its elongated shape, which creates torques that act on the object. [13], The discovery images were taken on 15 May 2005 and 18 May 2005. Why do these miniature worlds fascinate space explorers so much? The two newly named moons were intentionally named that the order of their initials N and H honors the New Horizons mission to Pluto, similarly to how the first two letters of Pluto's name honors Percival Lowell. Bill Dunford.
(2006). [2][30] As a result of this "Laplace-like" 3-body resonance, it has conjunctions with Styx and Hydra in a 2:3 ratio. [2], Nix was found by the Hubble Space Telescope Pluto Companion Search Team, composed of Hal A. Weaver, Alan Stern, Max J. Mutchler, Andrew J. Steffl, Marc W. Buie, William J. Merline, John R. Spencer, Eliot F. Young, and Leslie A. [24] With an image resolution 3 km (1.9 mi) per pixel, Nix's shape was often referred to as a "jelly bean" shape.
Whether you're doing it for the nerd cred or the pie, this week on #10Things, we've got all the ways you can celebrate #PiDay with NASA. The names of features on the bodies in the Pluto system are related to mythology and the literature and history of exploration.

[27][28] The nearly circular and coplanar orbits of Pluto's moons suggest that they may have gone through tidal evolutions since their formation. Before its size was directly measured, the moon was calculated to have a diameter of between 46 km, if its reflectivity is similar to Charon's 35%, and 137 km, if it had a reflectivity of 4%, like the darkest Kuiper belt objects.
The name Nix was approved by the International Astronomical Union (IAU) and was announced on 21 June 2006 along with the naming of Hydra in the IAU Circular 8723. [10] Derived from crater counting data from New Horizons, the age of Nix's surface is estimated to be at least four billion years old. H. A. Weaver; S. A. Stern, M. J. Mutchler, A. J. Steffl, M. W. Buie, W. J. Merline, J. R. Spencer, E. F. Young and L. A.
The formal name "Nix", from the Greek goddess of darkness and night, and mother of Charon, was announced on June 21, 2006 on IAU Circular 8723,[6] where the designation Pluto II is also given. NASA's Mars Odyssey spacecraft has captured these six infrared views of the Martian moon Phobos. Template:Moons of dwarf planets

Nix Moon are a six-piece band not shy of a little bit of musical experimentation. It was found along with Hydra in June 2005 by the Hubble Space Telescope Pluto Companion Search Team. As with Hydra and perhaps the other small Plutonian moons, Nix tumbles chaotically; the moon's axial tilt and day length vary greatly over short timescales. Vos articles vus récemment et vos recommandations en vedette. Young. [3] It was discovered along with Pluto's outermost moon Hydra on 15 June 2005 by the Pluto Companion Search Team. Amanda Barnett [21], Nix orbits the Pluto-Charon barycenter at a distance of 48,694 km (30,257 mi), between the orbits of Styx and Kerberos. The discovery images were taken on May 15, 2005 and May 18, 2005; the moons were independently found by Max J. Mutchler on June 15, 2005 and Andrew J. Steffl on August 15, 2005.

Of Pluto's smaller moons, only Nix and Hydra were imaged at resolutions high enough for surface features to be visible. Découvrez Lick Spoon de Nix Moon sur Amazon Music. Early research appeared to show that Nix was reddish like Pluto and unlike the other moons,[9] but more-recent reports have been that it is grey like the remaining satellites.
[11] In this case, Nix would likely have regoliths originating from the impact. In accordance with IAU guidelines concerning the naming of satellites in the Solar System, the moon was named Nix. Pour calculer l'évaluation globale en nombre d'étoiles et la répartition en pourcentage par étoile, nous n'utilisons pas une moyenne simple. [4], Nix was imaged along with Pluto and its other moons by the New Horizons spacecraft as it flew by the Pluto system in July 2015. It was found along with Hydra in June 2005 by the Hubble Space Telescope Pluto Companion Search Team, composed of Hal A. Weaver, S. Alan Stern, Max J. Mutchler, Andrew J. Steffl, Marc W. Buie, William J. Merline, John R. Spencer, Eliot F. Young, and Leslie A. Comment les évaluations sont-elles calculées ? [2] Nix is slightly fainter than Hydra, suggesting that it is somewhat smaller in size.
The discoveries were announced on 31 October 2005, after confirmation by precoveries from 2002. Take your favorite fandoms with you and never miss a beat. Brightness Difference on 2005-05-15: (5th root of 100) ^ (Nix. [24], This article is about the moon of Pluto. [13] New Horizons determined that Nix is approximately Template:Convert/round kilometers (20 mi) across.[14]. [27] At the time of the formation of Pluto's smaller moons, Nix may have had a more eccentric orbit around the Pluto-Charon barycenter.
Nix's orbital period is close to a 1:4 orbital resonance with Charon, with a timing discrepancy of 2.8%; there is no active resonance. Nix and Hydra are roughly 5,000 times fainter than Pluto and are about two to three times farther from Pluto than its large moon, Charon, which was discovered in 1978. a Relative to the Pluto-Charon barycenter. [16] Detailed images of the moon have revealed at least 6 impact craters on it, the largest of which is about 15 km across. The moons were informally referred to as "P1" and "P2", respectively by the discovery team.[15]. Together with Hydra, Pluto's third moon, the initials are those of the New Horizons probe. Nix Moon, Dundalk, Ireland.
Image Credit: NASA/JHUAPL/SWRI. [12] The rotation period has actually increased by 10% since Nix was discovered. It was found along with Hydra in June 2005 by the Hubble Space Telescope Pluto Companion Search Team. Livraison accélérée gratuite sur des millions d’articles, et bien plus.
Template:Infobox planet. Russian Никта Nikta).
They are so small and so faint that scientists combined a short exposure of Pluto and Charon and a long exposure of Nix and Hydra to create images of them all together.

[11], Early research appeared to show that Nix was reddish like Pluto and unlike the other moons,[12] but more recent reports have been that it is grey like the remaining moons.[7]. Legendary explorers and visionaries, real and fictitious, are among those immortalized in the first set of official surface-feature names for Pluto's largest moon, Charon.
