Beyond Pluto—New Horizons' mission is not over yet
Jonti Horner And Jonathan P. Marshall, The Conversation
Pluto: Once shattered, twice shy Like our own Earth, Pluto has an oversized satellite, Charon. But how did this satellite system come to be? It also seems very unlikely they were captured – that just doesn’t fit with our observations. Pluto and its moons will therefore be the second shattered satellite system we’ve seen up close, and the results from New Horizons will be key to interpreting their formation.
