43 Ariadne (air'-ee-ad'-nee ([[Help:Pronunciation respelling key|key]])) 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 April 15, 1857 and named after the Greek heroine Ariadne.
Characteristics
Ariadne is very elongate (almost twice as long as its smallest dimension) and likely bi-lobed[3] 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°, 235°) with a 10° uncertainty[2]. This gives an axial tilt of about 105°.Trivia
For reasons unknown, "ASTEROID 43 ARIADNE" was included in a list of names of supporters of the NASA spacecraft Stardust that was stored on a microchip within the spacecraft.References
