Name conflicts with minor planets

Despite efforts for every named body in the Solar System to have a distinct name, due to a variety of circumstances, there are several real or apparent name conflicts between different Solar System bodies. Most of these conflicts are between asteroids and natural satellites of planets, which are named according to different but partially overlapping schemes. Most satellites are named after people and divinities in Greek and Roman mythology; this is rarely true of asteroids currently, with the exception of centaurs and Jupiter trojans, but formerly many asteroids had mythological names, which consequently came into conflict with the names of natural satellites.

Some of these bodies have exactly the same name, referring to the same mythological character. The earliest such conflicts possibly arose through not considering certain mythological names as "official"; for instance, the names Io, Europa, Ganymede and Callisto for the Galilean satellites of Jupiter were not used in astronomical literature of a certain era, their place being taken by Jupiter I, Jupiter II, Jupiter III, Jupiter IV (cf. Naming of moons).

In the earliest of these conflicts, the natural satellite was named first, and the conflict arose with the naming of an asteroid. These conflicts span the period 1858-1906.

Later conflicts arose in relatively recent times from giving newly discovered satellites the same names as those of asteroids. By this time, it was possibly felt that the true name of an asteroid such as "38 Leda" included its minor planet number, and so re-using the name for a satellite did not really create a conflict. These conflicts span the period 1975-2001, though some conflicts of this type had arisen earlier with some names used unofficially.

Some bodies have names of identical form, but were actually named for different persons or things.

Some objects have names that refer to the same mythological character, but slight variations in spelling prevent there from being a technical conflict.
