513 Centesima is a 50 km Main-belt asteroid orbiting the Sun. It is one of the core members of the Eos family of asteroids. Relatively little is known about this tiny asteroid. It is not known to possess any natural satellites, so its mass is unknown, and therefore can only be estimated. However, it has a rather rapid rotation period of just over 5 hours. This fact can be utilized to determine that the asteroid must be excepionally dense in order for it to not fall apart. This enables a density estimate. It was discovered August 24, 1903 by late 19th and early 20th century astronomer Max Wolf. It was his 100th asteroid discovery, hence the name, which in Latin, means "hundredth".
