I read a middle school level science book talking about the sun, it says that the sun is circulating the Milky Way center with a speed of 250 km/s, and at the same time it is flying to the direction of M13 cluster with a speed of 20 km/s. It does not say if the M13 is closer or farther to the center of Milky Way than the sun. If M13 is closer than the sun, then the sun is moving closer to the center of Milky Way, or the sun is moving way from the Milky Way if M13 is farther than the sun. It is really confusing. Is the M13 cluster a member of Milky Way?
