Dwarf galaxies are generally smaller and less luminous than normal
galaxies. They may be associated with larger spiral galaxies and may
make up part of a galactic halo. Most dwarfs can be classified as Dwarf
Spheroidal (dSph) or Dwarf Elliptical (dE), but if they are undergoing a
burst of star formation, they may be classified as Blue Compact Dwarfs
