If The Sun Is Hot, How Is Outer Space Cold?

"If the sun is hot how is outer space cold ?" Excellent question, Jacoby Brissett, current quarterback of the Indianapolis Colts. It turns out that outer space is full of extreme temperatures. The sun is a ball of gas and fire measuring around 27 million degrees Fahrenheit at its core and 10,000 degrees at its surface. Meanwhile, the cosmic background temperature-that is, the average temperature of outer space-hovers at negative 455 Fahrenheit. The real oddity is Earth.
