Asteroid 2001 FE90 has been imaged by the JPL Planetary Radar Team.
Optical observations have revealed that the asteroid is small (200 metres), monolithic, and fast-rotating (P_syn = 28.66±0.06 min).
On the 19th June an optical spectroscopy was obtained by the Palomar 5-metre telescope; this revealed that the asteroid is a rare olivine-rich A-type asteroid, similar to asteroid (289) Nenetta.
