(7850) Buenos Aires was discovered on June 10th 1996 by Lucas M. Macri from the Fred L. Whipple Observatory, Mount Hopkins, Arizona, USA. It was named in honor of the capital of the Argentine Republic.

        

The above diagram (kindly prepared by Dr. Gareth Williams, Minor Planet Center, International Astronomical Union) shows the orbits of the planets Earth, Mars and Jupiter traced in light blue, while the orbit of (7850) Buenos Aires is traced in black. The positions of Earth, Mars, Jupiter and (7850) Buenos Aires at the time of its discovery are indicated by dots colored in light blue, red, dark green and light green, respectively.

The part of the orbit of the minor planet which is located below the plane of the Earth's orbit is shaded in grey. The perihelion (closest point to the Sun) is denoted by a "P". The solar system is viewed from the north ecliptic pole, and from this vantage point the planets revolve around the sun in a counter-clockwise motion.
