The Group Of Minor Planets The seeming gap in the solar system between the orbits of Mars and Jupiter naturally attracted the attention of astronomers as soon as the distances of the planets had been accurately laid down.

Was the vacancy real, or was it only because the planet which filled it was so small that it had escaped notice?

It received the name of Ceres, the goddess of the wheat field. It was a matter of surprise that the planet should be so small; and when its orbit became known it proved to be very eccentric. But new revelations were soon to come.
