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.<ref>Template:Cite book</ref>

Orbit

This object is orbiting the Sun with a period of Template:Convert, a semimajor axis of Template:Val, and an eccentricity of 0.18. Its orbital plane is at an inclination of 3.6° to the plane of the ecliptic. This is a stony S-type asteroid with a cross-sectional size of 60.2 km that is spinning with a rotation period of 25.2 hr.<ref name=jpldata/> Echo has been studied by radar.<ref name="detected">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It is not known to be a member of any asteroid family.<ref name=Carruba2016/>
