As usual, it depends on diameter and distance from the Sun, and anything else, like impacts, which can effect heating. -----Original Message----- From: pshugar <pshugar at messengersfromthecosmos.com> To: The List <meteorite-list at meteoritecentral.com> Sent: Mon, Dec 26, 2011 5:37 pm Subject: [meteorite-list] A good question we know that iron asteroids come from the cores of the differentiated bodies. The Whittmanstraden pattern is the slow cooling over exceedingly long periods of time. The question--what is the temp of the molten iron before it starts to cool.
