In contrast to spirals, the stars in ellipticals do not revolve around the center in an organized way. The stars move on randomly oriented orbits within the galaxy like a swarm of bees. tsw suggestionsDwarf ellipticals may be primordial objects. Within the currently favoured cosmological Lambda-CDM model, small objects (consisting of dark matter and gas) were the first to form. Because of their mutual gravitational attraction, some of these will coalesce and merge, forming more massive objects. Further mergers lead to ever more massive objects. The process of coalescence could lead to the present-day galaxies, and has been called "hierarchical merging".
