298 Baptistina is an asteroid orbiting in the asteroid belt. It is the namesake of the Baptistina family. It was discovered on 9 September 1890 by Auguste Charlois of Nice. The source of its name is unknown. It measures about 13 – in diameter. Although it has an orbit similar to the Flora family asteroids, it was once considered a possible source of the impactor that caused the extinction of the dinosaurs, a possibility ruled out by the Wide-field Infrared Survey Explorer (WISE) in 2011.
