I figure thusly. Our sun contains, as I understand, around 99.8% of the solar system’s mass. Jupiter contains most of the rest. The remainder was still enough to spawn Saturn and the other planets and asteroids and moons.
So, unless there are really, really greedy and efficient stars out there, I’m going to say that virtually every star has at least one rocky planet-sized thing revolving around it, either from leftover atoms or wandering planets that happened by and got captured during the several-billion years the star may have been around.
Earl Anthony (RIP) would have concurred, I’m sure.
Anyone disagree?
The Nebular theory says that spin is a factor. If a star forms with almost no spin at all, very little leftover debris should be present. What qualifies as a ‘planet’? Pluto doesn’t pass only because it hasn’t cleared its orbit. A system with very little leftover debris won’t contain any planets according to our definition.
I'm going to SPARE you a rebuttal Larry and just say that your comment was a STRIKE out......

Well your qualifications are stellar.
