94 Aurora is one of the largest main-belt asteroids. With an albedo of only 0.04, it is darker than soot, and has a primitive composition consisting of carbonaceous material. It was discovered by J. C. Watson on 6 September 1867 in Ann Arbor, and named after Aurora, the Roman goddess of the dawn.
This asteroid is orbiting the Sun with a period of 5.62 years and a relatively low eccentricity of 0.092. It is spinning with a rotation period of 7.22 hours. Observations of an occultation using nine chords indicate an oval outline of 225×173 km. The asteroid's pole of rotation lies just 4–16° away from the plane of the ecliptic.
