9403 Sanduleak is a minor planet
Minor planet
An asteroid group or minor-planet group is a population of minor planets that have a share broadly similar orbits. Members are generally unrelated to each other, unlike in an asteroid family, which often results from the break-up of a single asteroid...

Nicholas Sanduleak
Nicholas Sanduleak was an American astronomer.-Biography:Sanduleak's parents were born in Romania. His family moved to Cleveland soon after he was born, where Sanduleak did undergraduate work at the Case Institute of Technology, receiving a B.S. in 1956...
