In 2013, scientists started the Satellites Around Galactic Analogs (SAGA) Survey to find small galaxies orbiting larger ones, like the Milky Way. Recently, SAGA published three papers showcasing the Milky Way’s uniqueness after studying 101 similar satellite systems.
In the first study, scientists identified 378 satellite galaxies in 101 systems similar to the Milky Way. The SAGA Survey found that systems with a large satellite, like the LMC, usually have more satellites overall, with the Milky Way being an exception.
