Planet Nine: the movie

When I am not searching for Planet Nine, I am teaching classes here at Caltech and throughout the world. The most fun class is my online class The Science of the Solar System. It is a 100% free online class hosted at Coursera for anyone in the world. I've been running the class for several years now, and I finally got around to updating the class to include a short lecture on Planet Nine. For fun I thought I would post a copy here just to keep everyone up to date on my favorite yet-unseen planet. It's about 20 minutes long, and extra amusing if you watch it at double speed. CLICK HERE to watch it on Youtube,


If you enjoy this lecture, you might enjoy the whole class. Give it a try. It is, after all, entirely free.

  4. hi Mike,
    for your information planet nine is tilted 45 degrees not 30.
    it has three colors of rays: 1- yellow 2- red 3- blue.
    it will show up suddenly from the south.

    it affects the moves of the moon and the sun, and the cause of seeing solar eclipse and new moon at the same time.

  7. Thanks for the update! I've taken your Coursera class twice because i found it difficult but wonderful. I studied and learned so much the first time, but the the review broadened my understanding.

  8. Skeptical question: if Planet 9 exists, how can its orbit be so elliptical? Shouldn't its orbit have become nearly circular after billions of years, same as all the other big planets?
