Ursa Major I Dwarf Galaxy
- Distance From Earth: 330,000 Lightyears
- Number Of Stars: Over 100 Million
Ursa Major I is a dwarf galaxy that is actually a satellite galaxy to the Milky Way, found in the Ursa Major Constellation. This is likely why it is so close at just 330,000 lightyears from Earth. It is fairly new to us as it was only discovered in 2005. It likely took so long because the system is relatively faint and hard to see. Thus, we had to wait for technology to advance. Ursa Major Dwarf II would be discovered in 2006. Both have stars that are likely dying off. We have seen a little over 100 stars and most are around 10 billion years old. Interestingly, 21 of the stars we’ve seen have planets around them with habitable alien worlds.
If they saw Earth as it looked around 300,000 years ago, they would be seeing the Neanderthal group of early humans. They were considered relatively dumb compared to other ancient humans. Yet they were the ones who drew on caves, made incredible early tools, understood fires, developed small societies, and more. We were in the Chibanian period or truly late Middle Pleistocene. While not a technical ice age, glacial temperatures were commonplace for several early humans. Alien worlds would see an icy Earth, with spots of early humans trying not to freeze to death.
