What type of objects exert gravitational pull? only living objects only space objects all objects having mass all substances that are visible

The answer would be all objects having mass because if the object has mass the gravitational pull can get a hold of that object and bring it to its normal place for example an object on earth like lets say a ball, if you throw it up in the air it always comes back down. That is because it has mass.
