Echo (minor planet designation: 60 Echo) is a quite large main-belt asteroid. It was discovered by James Ferguson of the United States Naval Observatory in Washington D.C., on September 14, 1860. It was his third and final asteroid discovery. It is named after Echo, a nymph in Greek mythology. James Ferguson had initially named it "Titania", not realizing that name was already used for a satellite of Uranus.[1]
