1999 xs35
1999 XS35 is a near-earth object discovered in 1999 having a comet-like orbit. Its semi-major axis is 17.8 AU. Its orbital eccentricity is 0.94, which means that at the perihelion 1999 XS35 comes as close as 0.9 AU to the Sun, while at the aphelion it reaches beyond the orbit of Neptune. 1999 XS35 is a damocloid. 1999 XS35 is a small object with an absolute magnitude (H) of 17.2, which implies a size of about 1 km.
1999 XS35 came to perihelion on 21 October 1999, passed 0.0453 AU (6,780,000 km; 4,210,000 mi) from Earth on 5 November 1999, and was discovered on 2 December 1999 at about apparent magnitude 16.9.
