43 Ariadne /ˌæriˈædniː/ 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 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 (β, λ) = (-15°, 253°) with a 10° uncertainty. 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.
  • The maximum apparent size of Ariadne is equivalent to the maximum apparent size of Pluto.
