Sagittarius Dwarf Galaxy (SagDIG)
M 31 / NGC 598. This minor irregular galaxy is located at the opposite end of the galactic core to settled space. The Sagittarius Dwarf Galaxy is approximately 10,000 light years in diameter, and roughly spheroid in shape. It is adjacent to, possibly colliding with, the base of the Outer Arm. Relativistic exploration missions have departed for this galaxy but are not expected to arrive for many tens of thousands of years.
