- behnamoh 6y agowait, 2020 is not over yet...
- kzrdude 6y agoI assume M-plus means Mass of earth?
- NamTaf 6y agoYes. Similarly, M with a dot in the circle is the sun.
- dyslexit 6y agoAnd at 5M⊕ would have a diameter of about 9cm (or at 10M⊕ about the size of a bowling ball).
- echelon 6y agoHow would we ever find that? Gravitational lensing of the background stars? Do we stand a chance of uncovering it at all? Edit: from the abstract, > The observational constraints on a PBH in the outer Solar System significantly differ from the case of a new ninth planet. This scenario could be confirmed through annihilation signals from the dark matter microhalo around the PBH Wild.
