Pluto’s again, child! Seventeen years after it was demoted from planet to dwarf planet, it’s time for Pluto to retake its former title…at the least in line with our hosts, Chelsea Whyte and Leah Crane.
In this episode of Dead Planets Society, Chelsea and Leah get into the nitty-gritty of what it might take to formally make Pluto a planet – not by altering the foundations laid out by the International Astronomical Union, however by altering the photo voltaic system. They are joined of their quest by Kathryn Volk on the University of Arizona and Konstantin Batygin on the California Institute of Technology.
Of the necessities to formally be a planet, the one Pluto misses out on is the power to clear its orbital path of particles: the distant little world is simply not large enough to comb away all the opposite rocks in its orbit. So what if it have been larger? It would take a whole lot of mass to make that occur, and there can be penalties to super-sizing it.
Maybe it might be simpler to easily drag Pluto to a greater orbit, someplace that’s already principally empty – so long as that orbit is way sufficient from the solar that Pluto doesn’t simply evaporate. There is at all times the choice to drop a small black gap into Pluto or shrink the photo voltaic system round it. Those could also be more durable to perform, however our hosts are as much as the problem.
Dead Planets Society is a podcast that takes outlandish concepts about the best way to tinker with the cosmos – from snapping the moon in half to inflicting a gravitational wave apocalypse – and topics them to the legal guidelines of physics to see how they fare.
