EARLY PLANET SHAKE UP

Sky at Night Magazine - - BULLETIN -

Re­cent re­search into the bi­nary as­teroid Pa­tro­clus and Me­noetius points to a very early re­arrange­ment of our So­lar Sys­tem. Most plan­e­tary sci­en­tists agree that the gas gi­ants mi­grated to their cur­rent po­si­tions af­ter form­ing in a dif­fer­ent or­bit, grav­i­ta­tion­ally up­set­ting the So­lar Sys­tem in the process. It’s not clear when this hap­pened, but the sur­vival of a frag­ile bi­nary like Pa­tro­clusMe­noetius sug­gests it hap­pened within the first 100 mil­lion years of the So­lar Sys­tem.
