2000 DP 107 is a binary asteroid whose diameters are 800 and 300 metres and an orbital period of 1.77 days. The semi major axis is 2.6 km. IAUC 7503
2000 EB173 A Kuiper Belt Object with an estimated diameter of 600 km.
2000 SG344 has speculatively been thought to be the upper stage of the Apollo 12 SIV-B rocket, but Alan W Harris, of NASA's Jet Propulsion Laboratory claims that this object is natural. Ref: Minor Planet Mailing List
2000 UG_11 a binary asteroid with diameters of 230 and 100 metres.[IAU Circular Number 7518]
2000 WR106 is a Kuiper Belt Object with a mean distance from the Sun of 43 AU (6400 million km), inclination 17 deg and an eccentricity of 0.06. Best estimate of its diameter is 900km but it could be as big as 1,000 km or as small as 750 km.
"Thus, 2000 WR_106 is about half the size of Pluto. Its surface is, on average, about eight times darker, suggesting the absence of widespread surface frost." Quoted from [IAU Circular Number 7554]
2000 XK47 is thought to have a diameter of about 0.5km or even less and a rotation period greater than 2 hours. Its albedo is probably quite high.
2000 YA passed within 0.0049 AU from the Earth on Dec. 22.28 the estimated size is about 50 m. [IAU Circular Number 7544]
2001 AV43 passed within 0.0090 AU from the Earth on December 29, 2000.
2001 KX76 The largest asteroid in the Solar System.
2001 OG108 The largest Earth-crossing asteroid known. It has an estimated diamter of 15 km (10 miles) and will pass the Earth in April 2002 at about 45 million kilometers (28 million miles) so poses no risk to the Earth. [More]
2001 QJ142 has speculatively been thought to be the upper stage of a rocket, but Alan W Harris, of NASA's Jet Propulsion Laboratory claims that this object is natural. Ref: Minor Planet Mailing List
Asteroid 2002 NT7 This asteroid, discovered on 9th July 2002, has a small chance of hitting the Earth in the year 2060. It is expected that further observations will prove that the asteroid will not hit the Earth at all in 2060, but at the moment a small risk does remain. More information.
Asteroid 2003 SQ222 became the closest object to pass the Earth without impacting the atmosphere. The asteroid, perhaps 3 to 6 metres in diameter-the size of a room or house-came within 88,000 km of Earth late on Friday, 27 September 2003. Less than a quarter of the distance to the Moon, this is the closest well-documented Earth encounter of an asteroid that has not struck our atmosphere. More information
