Still Waters Posted January 23, 2018 #1 Share Posted January 23, 2018 Pluto hogs the spotlight in the continuing scientific debate over what is and what is not a planet, but a less conspicuous argument rages on about the planetary status of massive objects outside our solar system. The dispute is not just about semantics, as it is closely related to how giant planets like Jupiter form. Johns Hopkins University astrophysicist Kevin Schlaufman aims to settle the dispute. In a paper just published in the Astrophysical Journal, Schlaufman has set the upper boundary of planet mass between four and 10 times the mass of the planet Jupiter.https://phys.org/news/2018-01-scientist-definition-planet.html 3 Link to comment Share on other sites More sharing options...
