Sagittarius Dwarf Spheroidal Galaxy
- Distance From Earth: 70,000 Lightyears
- Number Of Stars: Hundreds Of Millions
The Sagittarius Dwarf Spheroidal Galaxy is pretty unique. Astronomers classify it as an “elliptical loop-shaped satellite galaxy,” which is quite the mouthful. Elliptical galaxies are known for offering a crisp, spherical shape that offers a nearly featureless image. While Sagittarius does this, it also happens to be looped more than perfectly spherical. The Milky Way and its gravity might be whose to blame for that. While it is roughly 50,000 lightyears from the center of the Milky Way, we rest near the outer banks. That means it needs another 20,000 lightyears to reach us. They are still one of our closest galaxies.
While we only know of a little over 80 stars, we know several of their stars contain potential alien worlds. If they were looking at Earth, they’d be seeing a really interesting time for us 70,000 lightyears away. Homo sapiens officially began to populate the Middle East. We’d slowly move into Africa over the next few thousand years. This was very late into the Pleistocene too. Oxygen levels were much lower by this point, so a lot of the megafauna became extinct. The Würm glaciation took place in this time, leading to the European Alps becoming glacial.
