Ninth planet

Last year, we discovered a new planet in our solar system. We haven't named it yet.
Planet Nine is hypothesized to follow a highly elliptical orbit around the Sun, with an orbital period of 10,000–20,000 years. The period with which it goes around the sun is a rational multiple of the periods of all the furthest Kuiper Belt objects. The planet's orbit would have a semi-major axis of approximately 700 AU, or about 20 times the distance from Neptune to the Sun, although it might come as close as 200 AU (30 billion km, 19 billion mi), and its inclination estimated to be roughly 30°±10°. The high eccentricity of Planet Nine's orbit could take it as far away as 1,200 AU at its aphelion. A probe could fly past it in 20 years time, however we haven't been able to get an accurate picture of it since it's so far away, but once we detect it properly (we only can by gravitational waves) it will be given a name that will be similar to one of a roman god like the other 7 planets (Pluto is no longer a planet.)

Since it's likely to be a gas giant, it's also going to be a very cold planet so only extremeophile bacteria could live in it

R.I.P. Pluto

I was taught that Pluto is the ninth planet as a kid, just like my dad, and his dad before him, and gosh darn it, it will always be the ninth planet as far as I am concerned.

Pluto will always be a ninth planet to me.

When I was a child I already found it odd that Pluto is so small and has such a curved orbit. So it's kind of logical.

We should name it Pluto.

But then we would have two planets named Pluto, because you know, there's already one that exists, we don't need two.
