“Thousands of years ago, when Uranus was forming, something, and we’re not sure what, smashed into it. The impact was so forceful that its axis tilted by ninety-eight degrees. It still spins but on its side. There’s no other planet in our solar system that’s tilted that much.” I look at her. “That’s you, Sara. You took a hit, it knocked you off your axis, but you keep spinning no matter what.”
