Pluton: razlika između inačica

 

=== Površina ===

Ravnine na površini Plutona sačinjene su od više od 98 posto [[Čvrsti dušik|dušičnog leda]], s tragovima metana i [[Ugljikov (II) oksid|ugljičnog monoksida]].<ref name="tobias"><cite class="citation journal">Owen, Tobias C.; Roush, Ted L.; Cruikshank, Dale P.; et al.
