If this planet shows up where they think it is, these two are headed for the history books. It would be the most exciting astronomical discovery for 100 years perhaps.
It would take Terminator to visit it which at 10 times Earth's gravity a man would weight 2,000 lbs and crush his spine not to mention break his legs and more trying to stand up. So no 'one small step for a man, one giant leap for mankind' will be taking place on this planet even if it's got a rocky surface!
Wow, cool! Thanks for the great reporting Gizmag, you guys are on point
Hope they give it a name starting with P, so all my planetary mnemonics still work. my very educated mother just served us nine pickles

I like my planets to have nearly circular, non-crossing orbits.
The idea is not new, its called Niburu and been around for ages.
Nibiru! But for Chizzy, and the rest of us, the should call it "Pan", "Poseidon", "Prometheus" or "Psyche" I like "Psyche."
If it's Neptune size/mass it wouldn't have that kind of gravity, inchiki. "How strong is the gravity on Neptune? Although Neptune is much larger than Earth, its surface gravity is about the same as the surface gravity on Earth. This is because Neptune is made up of gases and is not solid like Earth. This makes Neptune very light for its size. The surface gravity on Neptune is about 110% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 110 pounds on Neptune (assuming you could find someplace to, well, stand)."
I'm sorry Prof. Brown, I'm still annoyed - my feathers remain ruffled. Pluto was my favorite planet and in spite of your chicanery, it still is. Your hypothetical planet nine is - - well - - purely hypothetical and furthermore, if it does someday materialize, you are still will remain in my astronomical dog house. I suggest a boycott of hypothetical planet nine. If you want to see the ninth planet, then train your telescope instead to Pluto.
Personally, I want the new planet to be named "DAVE. I think it sounds really catchy myself.
