Abstract

A specially interesting subgroup of asteroid families are young ones, i.e. those formed less than 10 Myrs ago. They have attracted a lot of attention since the first such family has been discovered in 2002. About 20 young families have been discovered so far, but new discoveries are still very important. Here we report discovery of four new young asteroid families. Three of them are located in the inner asteroid belt, namely the (525) Adelaide, (6142) Tantawi and (18429) 1994AO1, while the family of (2258) Viipuri is located in the middle part of the asteroid belt.
