  Sagittarius Dwarf Elliptical Galaxy - Wikipedia, the free encyclopedia
Roughly 10,000 light years in diameter, it is currently about 70,000 light years from Earth and travelling in a polar orbit at a distance of about 50,000 light years from the core of the Milky Way (about a third the distance of the Large Magellanic Cloud).
Not to be confused with the Sagittarius Dwarf Irregular Galaxy (Sag DIG).
Although it is one of the closest companion galaxies to the Milky Way, it is on the opposite side of the galactic core from Earth, and consequently is very faint, although it covers a large area of the sky.

 Milky Way Spiral Structure
The arms of the Milky Way, at least near the solar neighborhood in our Galaxy, are typically named for the constellations where (in the direction of which) more substantial parts of them are situated.
The next inner arm, sometimes labelled "-I", is called the Sagittarius or Sagittarius-Carina Arm, the next outer arm, labelled "+I", is the Perseus Arm.
These arms can be traced by deepsky objects, namely diffuse nebulae, open star clusters and associatons, (type II and Ib/Ic) supernova remnants, and main sequence stars of so-called "early" (hot) spectral types.

A suspected arm beyond the Sagittarius arm is the Centaurus (-2), or Norma-Centaurus arm.
Spiral arms may be persistent concentrations of material, with individual stars entering an arm, passing through, and finally emerging on the other side.
Because interstellar gas and dust overtake the arm and enter it on the inner edge of the spiral pattern, this theory also explains concentrations of star formation along the inner edges of arms.

Within these arms are many ordinary, intermediate-age disk stars, such as the Sun, together with the more showy Population I objects, in the form of young, hot stars, stellar associations, open clusters, diffuse nebulae, and the bulk of the interstellar matter from which future stars will form.
The galactic bulge and the much larger galactic halo contain Population II objects – mostly old stars and roughly 200 globular clusters, of which about 150 are known.
Lying dead center in the Galaxy is the Sagittarius A Complex, which is believed to be associated with a fl hole, material in orbit around this object, and a nearby supernova remnant.

Sagittarius lies between Earth and the nucleus of the Milky Way Galaxy, it is within the Sagittarius Spiral Arm which is the arm next inward from the Orion Spiral Arm in which Earth resides.
As a result, the Globular and Open Star Clusters and nebulous Clouds of gas and dust that dominate the nucleus and spiral arms of the galaxy are abundant.
Sagittarius was considered by the Greeks to be the "Archer," but it looks suspiciously like a tea kettle to me. The steam from the western spout is made up of the nebulae M-8, and M-20, and the Open star Clusters M-21 and M-23.

Molecular counterparts of five of the classical 21-cm spiral arms have been identified: the Perseus arm, the local arm (including Lindblad's local expanding ring), the Sagittarius arm, the Scutum arm, and the 4-kpc arm.
The region between the local arm and the Perseus arm is apparently devoid of molecular clouds, and the interarm regions of the inner Galaxy appear largely so.
CO spiral structure implies that the mean lifetime of molecular clouds cannot be greater than 100 million years, the time required for interstellar matter to cross a spiral arm.
