253 Mathilde is an asteroid from the main belt, discovered in 1885 and first visited by a human spacecraft in 1997.
In the early 22nd century, with some help from advanced extraterrestrial technology, it was fitted with engines capable of turning asteroid ore into propulsion. Launched on humanity's first interstellar mission, it has been accelerating ever since. Now 92 years into a 780 year journey, generations of inhabitants have come and gone in the colony built just below the asteroid's surface.
Communications with Earth involve many months of waiting, so the people of 253 Mathilde are on their own. Some remain dedicated to their mission, others would like to cancel it. Alien passengers have the luxury of sleeping their way through the centuries.
253 Mathilde maintains a steady population of 200 people and 6 Centaurians. Here's some brief biographical summaries:
