The mystery of the origin of Pluto’s “heart” has been solved

“Somewhere beneath Pluto’s ‘heart’ are fragments of a massive body that it has never been able to fully digest. We are used to thinking of planet collisions as incredibly intense events, but in the outer solar system, speeds are low and ice is very strong, so when recreating them, you need to be much more precise in your calculations and take into account a lot of contributing factors,” the study authors concluded.
