Buenos Aires is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Buenos Aires as potentially hazardous because its orbit does not bring it close to Earth.
Buenos Aires orbits the sun every 1,370 days (3.75 years), coming as close as 2.16 AU and reaching as far as 2.67 AU from the sun. Buenos Aires is about 3.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
Buenos Aires's orbit is 1.16 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.
Buenos Aires's orbit is determined by observations dating back to Feb. 19, 1977. It was last officially observed on June 21, 2023. The IAU Minor Planet Center records 2,118 observations used to determine its orbit.
