654 Zelinda is a minor planet orbiting the Sun that was discovered on 4 January 1908 by German astronomer August Kopff.
On favorable oppositions, it can be as bright as magnitude 10.0, as observed on January 30, 2016.
In 1988, this object was detected with radar from the Arecibo Observatory at a distance of 0.89 AU.
[3] Measurements made using the adaptive optics system at the W. M. Keck Observatory give a diameter estimate of 131 km.
It is roughly triangular in shape,[4] and spins with a synodic rotation period of 31.735 h.
