A deep basin called Sputnik Planitia, which makes up the “left lobe” of the heart, is home to much of Pluto’s nitrogen ice. The New Horizons spacecraft took an image of Pluto's heart on July 14, 2015. Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/NASAThrough new research on Sputnik Planitia, an international team of scientists has determined that a cataclysmic event created the heart. The teardrop shape of Sputnik Planitia is a result of the frigidity of Pluto’s core, as well as the relatively low velocity of the impact itself, the team found. The researchers believe that the new theory regarding Pluto’s heart could shed more light on how the mysterious dwarf planet formed.
