| Description | NGC 4647 makes a lovely contrast with M60... a spiral galaxy with lots of structure vs. eliptical with virtually none other than a bright center. Certainly does appear that M60 is perturbing NGC 4647. Assuming NGC 4647 was close to circular when formed, the attraction has elongated its current shape and given the center of mass a slight kink to the south (towards M60). |
