Dear Neal, You were the inspiration for my daughter’s name Nova. She passed away 6 years ago at 1year and two days old. I still watch you in her honor. Thank you for inspiring her name. She is my little star.

Wild to hear about planet X again. Im 33 years old, and in elementary school planet X was something everyone spoke of... then suddenly not only does it stop, but nobody even remembered talking about it.

The fact that Neptune is twice the distance from the sun the Uranus but still has an effect on its orbit still blows my mind.
