Interposita means in Latin in between . The name is derived from the anecdote that the discovery film was hastily exposed between two satellite laser distance measurements in the neighboring dome.
The planetoid is part of the Eos - asteroid family . It is believed that the family was formed about 1.1 billion years ago through a collision from an original asteroid.
