298 Baptistina is a typical Main belt asteroid.
It was discovered by Auguste Charlois on September 9, 1890 in Nice.
Although it has an orbit similar to the Flora family asteroids, it was found to be an unrelated interloper (M. Florczak et al A Visible Spectroscopic Survey of the Flora Clan, Icarus Vol. 133, p. 233 (1998)).
