99943 (2005 AS2) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2005 AS2 as potentially hazardous because its orbit does not bring it close to Earth.
2005 AS2 orbits the sun every 4,450 days (12.18 years), coming as close as 4.72 AU and reaching as far as 5.87 AU from the sun. 2005 AS2 is about 22.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
2005 AS2's orbit is 3.75 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2005 AS2's orbit is determined by observations dating back to June 21, 1996. It was last officially observed on Oct. 19, 2022. The IAU Minor Planet Center records 1,612 observations used to determine its orbit.
