3. Who Discovered It! Mike Brown and Konstantin Batygin.
Body nearly the size of Neptune.
Orbits the sun every 15,000 years.
Orbit is similarly titled.
The closest approach to the sun is 7 times of Neptune

4. What is it made of?
--But a thick hydrogen atmosphere, with high pressure at depth, is remarkably opaque to infrared radiation and serves as a great thermal blanket.
--It is therefore possible that in some deep layer there are conditions suitable for liquid water to exist - making this a world with a dark ocean whose surface might be comparable in pressure and temperature to Earth's abyssal depths.
--Whether that could actually support life is another question.
__Unless the rocky core was also in contact with the ocean there might not be enough chemical feedstock for any kind of biological system to function.

5. Why was it discovered? It was Discovered using computer simulators.
At a certain time they’ll be able to see it with a sophisticated telescope.
The planet, if it exists, has a mass 10 times that of Earth and takes between 10,000 and 20,000 years to orbit the sun.
"There have only been two true planets discovered since ancient times, and this would be a third. It's a pretty substantial chunk of our solar system that's still out there to be found, which is pretty exciting."- Brown

6. Where was it when it was discovered?
If this ninth large planet is out there, it’s so distant and so dim that it isn’t surprising the world hasn’t been detected yet.
“We don’t know exactly where it is, or else we’d just point the telescope at it tomorrow and it would be right there. But the sky is really big and this thing might be pretty faint, depending on how far out it is,” says Chad Trujillo
At such extreme distances, even a relatively large planet wouldn’t have a heat signature detectable by current surveys, and it wouldn’t reflect much sunlight.

7. Where it is now?
It is believed to have a mass about 10 times that of Earth and orbits about 20 times farther from the Sun on average than does Neptune. As a result, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the Sun.
Therefore we do not know its exact location in its orbit.

Astronomers say they have evidence of a ninth planet in our solar system. Here's what they say they know about it. (Joel Achenbach,Gillian Brockell/The Washington Post)
Astronomers at the California Institute of Technology announced Wednesdaythat they have found new evidence of a giant icy planet lurking in the darkness of our solar system far beyond the orbit of Pluto. They are calling it "Planet Nine."
Their paper, published in the Astronomical Journal, estimates the planet's mass as five to 10 times that of the Earth. But the authors, astronomersMichael Brown and Konstantin Batygin, have not observed the planet directly.
