NGC 1553
NGC 1553 is a prototypical lenticular galaxy in the constellation Dorado. It is the second brightest member of the Dorado Group of galaxies. British astronomer John Herschel discovered NGC 1553 on December 5, 1834 using an 18.7 inch reflector. ==Interacting galaxy== It forms a pair of interacting galaxies together with elliptical NGC 1549〔 which lies 11′.8 away from it in the sky. Their interaction appears to be in the early stage and can be seen in optical wavelengths by faint but distinct irregular shells of emission and a curious jet on the northwest side.〔〔 Together, these two galaxies comprise the center of the Dorado group.
