9950 ESA, provisional designation 1990 VB, is an eccentric asteroid and elongated near-Earth object of the Amor group, approximately 1.7 kilometers in diameter.

It was discovered on 8 November 1990, by French astronomer Christian Pollas at the Centre de recherches en géodynamique et astrométrie (Cerga) at Caussols in southeastern France.

Lightcurve analysis gave a rotation period between 6.707 and 6.712 hours with a brightness variation of 0.44 to 0.89 magnitude (U=3/3/3-).

[6][7][8][a][b] A high brightness amplitude typically indicates that the body's shape is irregular and elongated, rather than spherical.

In the early 1990s, David Tholen at the Institute for Astronomy of the University of Hawaii estimated a diameter of 3 kilometers for ESA.
