Abstract: Spectacular images, taken during the flyby of 81P/Wild 2 by the NASA Stardust spacecraft, were used to determine that the shape of the comet 81P/Wild 2 nucleus can be reasonably modeled as a triaxial ellipse having radii 1.65 × 2.00 × 2.75 km ± 0.05 km (1σ). The shortest axis, considered the rotational axis, has a right ascension of 110° and a declination of −13°. The longest axis, used to define zero longitude, has an argument of prime meridian angle of 155°. All angles use the IAU definitions, are relative t…
