Leaving Occam's razor behind for a second, could this not also be explained by multiple objects whos mass and orbits sum up to the expected properties of a proposed Planet 9?
- amelius 10y agoAnd could these objects lie far outside our solar system?
- muninn_ 10y agoIt's possible I suppose, but it seems kind of strange that a planet-size group of rocks are floating exactly together in an orbit without colliding, or knocking each other about. What seems simpler? That we have a group of rocks the size of Neptune floating together, or that they actually formed together into a planet? I'm not an astrophysicist, but I'm not sure what else it would be. Looking forward to the proof or refutation.
- runeb 10y agoI didn't necessarily mean the object were very near each other. Just wondering if there could be some set of objects out there that would, in sum, have the observed effect on the inclination of the solar system and orbits of far-away objects.
- muninn_ 10y agoWell, in order to have that affect those groups would have to be close together wouldn't that? (serious question)
- smallnamespace 10y agoObjects in the same orbit tend to coalesce over time because of gravity (hence planets)
