# MGC1

MGC1 is a globular cluster in the constellation of Pisces. It lies about 65,000 light-years (about 200 kpc) away from the Andromeda Galaxy (M 31)'s galactic center.[4] MGC1 is considered as one of the most isolated globular clusters in the Local Group.[4] The radial velocity of MGC1 is close to the systematic velocity of M 31 and likely within its escape velocity, therefore the cluster is likely gravitationally bound to it.[1] Its absolute magnitude is −8.5.[1]
