Triangulum I Galaxy
- Distance From Earth: 3 Million Lightyears
- Number Of Stars: 40 Billion
Among the “local group” of full galaxies, Triangulum I is the third largest. In fact, it is considered the furthest universal body that can be seen with the naked eye. Roughly 3 million lightyears away, it is believed to be one of Andromeda’s satellite galaxies. Yet some scientists think it’s actually coming out of a previous interaction with another galaxy. Then as it reached the massive Andromeda and its gravitational pull, it had no choice but to become a satellite. Interestingly, Triangulum I has an H II nucleus. Which is simply a nucleus made of ionized atomic hydrogen.
If alien worlds viewed Earth from here, they’d be seeing some changes. First, they would be seeing the North Pole start to become glacial. We’d also begin to see some animals pop up that are often assumed to be part of the dinosaurs. Species like the saber-toothed tiger and wooly mammoth were both common in this timeframe. Both even lived long enough to come in contact with early humans. Neither are dinosaurs, obviously, but they are still part of the prehistoric species list. Not only this, but other megafauna popped up in this time, including several much larger plants.
