Since neutrinos have some mass, they could be at rest. What would a planet sized ball of neutrinos look like?

If a large ball of neutrinos was held together by its own gravity, would objects pass right thru it? Would objects in orbit around it appear to be orbiting nothing? Has anything like this been seen in astronomy?

    Well, other than the obvious that a ball of neutrinos couldn’t form because they have very low gravity and move at high speed, yes you could pass through it and yes it would be invisible.
