Behold Uranus in all its glory! The seventh planet from our sun, famous for two things: its sideways rotation and being the butt of every astronomy joke since 1781. While the factoid about 63 Earths fitting inside is scientifically accurate, the creator knew exactly what they were doing with that phrasing. Just remember, whenever you're giving a planetary presentation and mention this ice giant, prepare for the inevitable snickering from the back row. Even after 30 years of teaching, I still have to pause for the giggles to subside.
