Two-faced orb, more Janus than Janus,
light and heat separate soot from frost
in a place where tons are pounds
and Roland's song still echoes
from Laurentia to Baltica.
Around its world in eighty days,
its showier sibling spits salt to gain fame.
But he, a mystery from Cassini to Cassini,
can wait a while longer for someone to crack the walnut.
