Pluto has an x-ray source - which is a surprise and it is in the range
of Rydberg energies from Millsean transitions from nickel and iron
200-300 eV.
Pluto is mostly ice, not dense - but could have iron/nickel debris from
meteorite impacts over the past few billion years.

Pluto is alive—but where is the heat coming from?
