Selected Notable Spacewatch Discoveries



The following table shows some of the more interesting objects that have been discovered by Spacewatch in recent years. The table lists the object's designation along with its closest approach to the Sun (perihelion), furthest distance (aphelion), and inclination of the orbit to the plane of the ecliptic.
