NGC 7010 is a massive elliptical galaxy located about 365 million light-years from Earth in the constellation Aquarius.[2][3] NGC 7010 was discovered by astronomer John Herschel on August 6, 1823, and was later listed by French astronomer Guillaume Bigourdan as IC 5082.[4]
Physical characteristics
NGC 7010 has broad, plateau shaped shells of stars surrounding it.[5] Its theorized that the shells formed from the accretion of another galaxy.[6]
