Thus quoth Benji as he explained the theory of why astronomers think there’s another planet out way past Pluto. Here’s what transpired.
I sat down to write a new daily board, which says the date and Benji’s agenda for the day. Before I started, Benji said, “Wait! I want to sure you something.”
A little background. Benji really wants to be an astronomer when he grows up, and whether he does or not, it’s a fun hobby for a kid with lots of interesting exercises and experiments. There are also tons of videos on space stuff, naturally. Benji’s especially interested in the hypothetical Planet 9, which is somewhere way out in the Kuiper Belt, or maybe father. Who knows.
