Shaulladany family
The Shaulladany family (010[1]) is a small collisional asteroid family of at least 13 known asteroids,[2] named for one of its members, the 16-kilometre (9.9 mi)-across asteroid 247341 Shaulladany (although its largest member is 37519 Amphios). It lies within the larger dynamical group of Jupiter trojans, a group of asteroids in an orbital resonance with Jupiter such that they stay about 60 degrees ahead of/behind the planet in its orbit at all times in the Lagrange points L4 and L5, with the Shaulladany family being part of the trailing cloud around L5, also known as the Trojan camp. All members of the family are dark (assumed to be C-type asteroids) with albedos of around 0.09.
An asteroid family is a group of physically related asteroids usually created by a collision with an original larger asteroid, with the fragments continuing on similar orbits to the original. This is distinct from a dynamical group in that the members of a dynamical group only share similar orbits because of gravitational interactions with planets, which concentrate asteroids in a particular orbital range. Members of the Shaulladany family are both part of the wider Trojan dynamical group, and fragments of 37519 Amphios. The family is considered a non-catastrophic asteroid family because 37519 Amphios, its largest member, makes up a majority of the family's total mass, rather than simply being the largest of a number of fragments each making up a small fraction of the original destroyed asteroid.[3]
