43 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.

Characteristics

Ariadne is very elongate (almost twice as long as its smallest dimension) and probably bi-lobed<ref name="Tanga03">Template:Cite journal</ref> or at least very angular. It is a retrograde rotator, although its pole points almost parallel to the ecliptic towards ecliptic coordinates (β, λ) = (−15°, 253°) with a 10° uncertainty.<ref name="Kaasalainen02">Template:Cite journal</ref> This gives an axial tilt of about 105°.

Studies

43 Ariadne was in a study of asteroids using the Hubble FGS. Asteroids studied include (63) Ausonia, (15) Eunomia, (43) Ariadne, (44) Nysa, and (624) Hektor.<ref name="Tanga 733–741"/>
