Since it is to my understanding that the earth's core has never been visited in person, how is it that geologists know or measure what the exact temperature of it is?

They measure the tempurature by using the properties of the earth magnetic fields in the earth.

The earth's core is predicted to be between 4,000 kalvins up to and over 7,000 kelvins. Scientists do not really excactly know, but these are just estimates. If we knew the melting temperature of iron at high temperatures, we would be able to predict this more acurately, because that is what it is mostly made of. The website http://www.sciam.com/askexpert/geology/geology7/geology7.html will explain this, and give a little more information.
