1999 XS35 is anear-Earth object discovered in 1999 having acomet-like orbit. Itssemi-major axis is 17.8 AU. Itsorbital eccentricity is 0.94, which means that at theperihelion1999 XS35 comes as close as 0.9 AU to the Sun, while at theaphelion it reaches beyond the orbit ofNeptune.[2]1999 XS35 is adamocloid.1999 XS35 is a small object with anabsolute magnitude (H) of 17.2, which implies a size of about 1 km.[4]
1999 XS35 came to perihelion on 21 October 1999,[2] passed 0.0453 AU (6,780,000 km; 4,210,000 mi) from Earth on 5 November 1999,[5] and was discovered on 2 December 1999 at aboutapparent magnitude 16.9.[1]
