Since the substance on the surface of the planet
never melts (from extremely high temps), does that mean it has an
extremely high melting point?  Could it be a substance that we haven't
discovered?  What is the substance?  What is the real boiling point?  What is
the substance called?  What is its molecular makeup?  Are we only suppose to ask
one question?  lol

720 K is the high temp that I got from a website.
