43 Ariadne43 Ariadne is a fairly large and bright main-belt asteroid. It is the second-largest member of the Flora asteroid family. It was discovered by N. R. Pogson on 15 April 1857 and named after the Greek heroine Ariadne.CharacteristicsAriadne is very elongate and probably bi-lobed or at least very angular. It is a retrograde rotator, although its pole points almost parallel to the ecliptic towards ecliptic coordinates = with a 10° uncertainty. This gives an axial tilt of about 105°.Studies43 Ariadne was in a study of asteroids using the Hubble FGS. Asteroids studied include Ausonia, Eunomia, Ariadne, Nysa, and Hektor.
