An elliptical galaxy has?

Almost no discernible structure

Galaxies are titanic swarms of tens of millions to trillions of stars, orbiting around their common center of gravity.

Elliptical galaxies have smooth, rounded shapes because the orbits of their stars are oriented in all directions. They contain little gas and dust, and no young stars. Like spiral galaxies, elliptical galaxies are surrounded by globular star clusters and dark matter.
