Boötes Dwarf



The Boötes Dwarf Galaxy (Boo I dSph) is a galaxy which appears faint, with a luminosity of 100,000 L☉ and an absolute magnitude of –5.8. It lies about 197 thousand light-years (60.4 kiloparsecs) away in the constellation Boötes. This dwarf spheroidal galaxy appears to be tidally disrupted by the M-0 Galaxy, which it orbits, and has two stellar tails that cross over to form a cross. Tidally disrupted galaxies usually only form one tail.

Like many of the ultrafaint dwarf spheroidals, the entire galaxy appears fainter than the star Rigel (absolute magnitude –6.8).

There is one known Ancient Gate Network connection to Boötes from M-0. It is guarded by GH Boötes Up (M-0 side) and GH Boötes Down (Boötes side). The Union's 11th Fleet is stationed here.

No direct contact with any spacefaring society has been made so far  in the Boo I dSph galaxy.
