+92 It's unlikely, but entirely possible for a 9th planet in our solar system to exist, but matching Earths orbit on the other side of the Sun so we can't see it. amirite?

No it's not. We have satellites orbiting the Sun and that's been the case for many years.

Plus, we already have a 9th planet. It's Pluto, and we owe it an apology... :D

Fun fact: one of the ways planets have been discovered was by witnessing their gravitational effect on the other planets and determining there had to be something there. If there were a planet on the other side of the sun from us, we would have known before we ever sent telescopes out of orbit.

If the idea is that it's in earth's orbital plane, that's easily disproven by preexisting observations and math. If the idea is that it's super distant, the planet would have an insanely fast orbital speed (to travel orders of magnitude greater distances in the same amount of time). That's highly unlikely that anything large enough to be considered a planet is also moving that fast _AND_ has avoided detection or even suspicion

1. we already have a ninth planet. 2. gravitational measurements disprove this hypothesis. 3. satellites and telescopes disprove it even more.

Pluto. Is the 9th planet

Well, based on that logic there are actually 17 planets.

Based, but you could even imagine a tenth planet that matches the 9th planet's orbit on the other side of the Sun. That would be crazier…
