  We consider a self-gravitating collisionless gas where the gravitational
interaction is modeled according to MOND (modified Newtonian dynamics). For the
resulting modified Vlasov-Poisson system we establish the existence of
spherically symmetric equilibria with compact support and finite mass. In the
standard situation where gravity is modeled by Newton's law the latter
properties only hold under suitable restrictions on the prescribed microscopic
equation of state. Under the MOND regime no such restrictions are needed.
