The elliptical galaxy Messier 60 has a close companion, the intermediate spiral NGC 4647 to the immediate northwest. The two are physically close to one another, but not so close that there are obvious signs of interaction between the two galaxies (though there are tenuous indications that such a gravitational interaction is beginning to take place).
