We also attempt to determine the temperature of H2O ice making use of the crystalline feature at 1.65 μm. The albedo and composition of Quaoar, in particular the presence of N2, if confirmed, make this TNO quite similar to Triton and Pluto.AB - Aims. Every page goes through "Quaoar" redirects here. We present a model confirming previous results regarding the presence of crystalline H2O and CH4 ice, as well as C 2H6 and organic materials, on the surface of this distant icy body. Trujillo's website on Quaoar gives a three-syllable pronunciation, Polar dimension calculated by multiplying the measured equatorial diameter In the convention for minor planet provisional designations, the first letter represents the half-month of the year of discovery while the second letter and numbers indicate the order of discovery within that half-month. Our goals are to determine to what degree this is true and to shed light on the chemical evolution of this icy body.Methods.
6,493,295,577 km Diameter. ", keywords = "Kuiper Belt, Techniques: Spectroscopic", author = "{Morea Dalle Ore}, C. and Barucci, {M. 285.97 Earth Years Discovery Date. What we do. You could also do it yourself at any point in time.It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology.According to Brown, Quaoar is correctly pronounced with three syllables. Quaoar was originally discovered in 2002 According to NASA , the object is about half the size of Pluto at 690 miles in diameter and is currently around 4 billion miles from the Sun. Conclusions. 50000 Quaoar – a cubewano and probable dwarf planet in the distant icy Kuiper Belt. We present new near-infrared (3.6 and 4.5 μm) photometric data obtained with the Spitzer Space Telescope.
We also attempt to determine the temperature of H2O ice making use of the crystalline feature at 1.65 μm. We perform spectral modeling of the entire wavelength range - from 0.3 to 4.5 μm by means of a code based on the Shkuratov radiative transfer formulation of the slab model. These data complement high resolution, low signal-to-noise spectroscopic and photometric data obtained in the visible and near-infrared (0.4-2.3 μm) at VLT-ESO and provide an excellent set of constraints in the model calculation process. We perform spectral modeling of the entire wavelength range - from 0.3 to 4.5 μm by means of a code based on the Shkuratov radiative transfer formulation of the slab model. We attempt a measurement of the temperature and find that stronger constraints on the composition are needed to obtain a precise determination. Jul 05 2018 12:23:20 UTC JD 2458305.016204 Thu Jul 05 2018 14:23:20 GMT+0200 (Ora legale dell’Europa centrale) We attempt a measurement of the temperature and find that stronger constraints on the composition are needed to obtain a precise determination. We present new near-infrared (3.6 and 4.5 μm) photometric data obtained with the Spitzer Space Telescope. We present new near-infrared (3.6 and 4.5 μm) photometric data obtained with the Spitzer Space Telescope. June 4 2002 Discoverer. Model fits indicate that N2 may be a significant component, along with a component that is bright at < 3.3 μm, which we suggest at this time could be amorphous H2O ice in tiny grains or thin grain coatings. The number comes from the Minor Planet Center and the name from the creation god of the Tongva people whose ancestors have lived in the Los Angeles area for a thousand years and more.
