“We’re the first people in 150 years who aren’t the crazy people.”


Mike’s an astronomer and Konstantin’s a theorist; put ’em together and it’s like peanut butter and chocolate. Presto – a new planet discovered!


Mike and Konstantin had to spend a year trying to disprove their discovery of the ninth planet in order to show that they were right; when they couldn’t disprove it, that meant they weren’t crazy… and that the other eight planets in our solar system had a new kid brother.
