Pluto Articles: Pluto Follows Its Cold, Cold Heart

Why is Sputnik Planum exactly facing away from Charon? This article examines Pluto's dynamics and draws the astonishing conclusion that its axis may actually be unstable, owing to the relative distribution of volatile ices on the surface. So what would actually happen if Sputnik Planum would at times melt up, as we propose in our book? Is it conceivable that on such occasions it might actually "see" Charon rising one day?

Falls jemand diesen Artikel noch nicht gesehen hat: Hier diskutieren Experten, warum das Sputnik Planum genau von Charon abgewandt ist, und kommen zu dem Schluss, dass Umverteilungen der flüchtigen Eise an der Oberfläche Plutos Achse zum Taumeln bringen können. Was würde also tatsächlich geschehen, wenn das Sputnik Planum sich zeitweise verflüssigte, wie wir in unserem Buch vorschlagen? Könnte irgendwann der Charon über seinem Horizont aufgehen?

Pluto follows its cold, cold heart


Sputnik Planum, the left lobe of Pluto’s heart, is a vast expanse of mostly frozen nitrogen that lies close to the dwarf planet’s equator — too close to be mere coincidence, two UA planetary researchers suggest. So much ice has piled up here that it could have dragged the entire planet with it and reoriented its spin axis, they think. Charon is seen in the background. (Image: James Keane)
