It’s just our luck that the temperature of the night sky (more commonly, the Cosmic Microwave Background) is two orders of magnitude colder than the Earth, and that the Earth is about an order of magnitude colder than a star. Nice place to be, thermodynamically, as Sean Carroll pointed out in a public lecture I previously wrote about.
