Radar observations of asteroid 7335 ( 1989 JA)

Radar observations of 1989 JA during its discovery apparition yielded dual-polarization echo spectra on two dates at Arecibo and three dates at Goldstone. The echoes indicate that this object has an effective diameter within a factor of two of 1 km, a rotation period less than half a day, and a surface that is fairly smooth at centimeter-to-meter scales.
