Exempel på hur du använder QUAOAR i en mening

• June 4 – The ringed dwarf planet Quaoar is discovered by astronomers Chad Trujillo and Michael Brown at the Palomar Observatory.
• This was the telescope that produced the images leading to the discovery of 50000 Quaoar in 2002, and 90377 Sedna in 2003 (published 2004) and the dwarf planet Eris.
• In December 2004, Luu and Jewitt reported the discovery of crystalline water ice on Quaoar, which was at the time the largest known Kuiper Belt object.
• Chad Trujillo, astronomer and co-discoverer of several Trans-Neptunian objects including Quaoar, Sedna, Orcus, and Eris.
• ESO analysis of spectra reveals a strong red slope and no presence of water ice (in contrast to Quaoar, also red) suggesting organic material (see comparison of colours and typical composition inferred from spectra of the TNOs).
• wrote that near-infrared spectroscopy by the James Webb Space Telescope (JWST) in 2022 suggests that Sedna, Gonggong, and Quaoar underwent internal melting, differentiation, and chemical evolution, like the larger dwarf planets Pluto, Eris, Haumea, and Makemake, but unlike "all smaller KBOs".
• Of these ten, two have been visited by spacecraft (Pluto and Ceres) and seven others have at least one known moon (Eris, Haumea, Makemake, Gonggong, Quaoar, Orcus, and Salacia), which allows their masses and thus an estimate of their densities to be determined.
• Thus SSSBs are: the comets; the classical asteroids, with the exception of the dwarf planet Ceres; the trojans; and the centaurs and trans-Neptunian objects, with the exception of the dwarf planets Pluto, Haumea, Makemake, Quaoar, Orcus, Sedna, Gonggong and Eris and others that may turn out to be dwarf planets.
• To be cautious, he advised the IAU to "officially" accept as dwarf planets the top three: Sedna, Orcus, and Quaoar.
• Teams by Mike Brown, Chad Trujillo and David Rabinowitz discovered the trans-Neptunian objects (TNO) Quaoar in 2002, Sedna in 2003, Orcus and Haumea in 2004 and Makemake in 2005, part of the most notable KBOs, some now regarded as dwarf planets.
• The surface is moderately red, meaning that Quaoar reflects longer (redder) wavelengths of light more than shorter (bluer) wavelengths.
• In the 21st century, several new planet-sized bodies, including Sedna (20px), Quaoar (20px), Orcus (20px), Gonggong (20px), Haumea (20px), Makemake (20px), and Eris (20px), have been discovered.
• These include most of the planetary-mass moons, such as Ganymede, Titan, Europa, Enceladus, and Triton; and also most of the known dwarf planets, such as Pluto, Orcus, Haumea, Makemake, Quaoar, Sedna, Gonggong, and Eris.
