Classical Kuiper Belt object with the absolute magnitude between that of (50000) Quaoar and (20000) Varuna, 2003 TX 300 has the most eccentric and inclined orbit of the three.

(Redirected from (20000) Varuna) 20000 Varuna (VAR oo na) is a Kuiper Belt object about 1060 kilometers in diameter, estimated from a combination of thermal and optical measurements. ...


Non-detection of thermal emission puts the upper limit of 907 km on its diameter and lower limit on albedo 0.08 (to compare with Varuna's diameter of 1060 km and albedo of 0.038 respectively). Albedo is the measure of reflectivity of a surface or body. ... (Redirected from (20000) Varuna) 20000 Varuna (VAR oo na) is a Kuiper Belt object about 1060 kilometers in diameter, estimated from a combination of thermal and optical measurements. ...


A variability of the visual brightness was also detected which could fit to 7.9 h or 15.8 h rotational period (the distinction between single or double-peaked curved cold not be made with confidence). The changes in brightness are quite close to the error margin and could also be due to irregular shape.


Infra-red spectrum indicates large quantities of water ice, similar to Quaoar, but visible spectrum is neutral (Quaoar is red). This article is about the trans-Neptunian object. ...

2002 TX300 is classified as a classical Kuiper belt object and follows an orbit very similar to that of 2003 EL61: highly inclined (26°) and moderately eccentric (e~0.12), far from Neptune’s perturbations (perihelion at ~37AU). Other mid-sizes cubewanos follow similar orbits as well, notably 2002 UX25 and 2002 AW197. Image File history File links TheKuiperBelt_Orbits_2002TX300_2003EL61_PolarView. ...

The diagrams show polar and ecliptic views of the orbits of the two cubewanos. The perihelia (q) and the aphelia (Q) are marked with the dates of passage. The present positions (as of April 2006) are marked with the spheres illustrating relative sizes and differences in albedo (both objects appear neutral in the visible spectrum). Very similar orbits for these 'hot' classical objects do not imply similar physical properties; 2002 TX300 is smaller and much dimmer (albedo<0.08) than 2003 EL61.
