Planet X

[edit]

is Planet x a reall planet —Preceding unsigned comment added by 75.164.239.245 (talk) 02:37, 15 February 2008 (UTC)[reply]

Not really. "Planet X" is a term used to describe any hypothetical object beyond Neptune whose existence is inferred through gravitational interaction. Right now there are at least two different "Planet X"-es being discussed in scientific literature, and no one knows whether either of them exist or not. If either of them were to be found, it wouldn't be Planet X anymore, but another Planet X might show up to replace it. So it's probably better thinking of Planet X as a concept, rather than as a planet.Serendipodous 08:16, 15 February 2008 (UTC)[reply]
If you consider if a planet X was discovered, then yes, planet X is real, and it's name is Pluto, but Pluto is no longer a planet. 76.66.198.46 (talk) 10:19, 14 November 2008 (UTC)[reply]
No, Pluto is not Planet X. Planet X was a planet large enough to perturb Neptune's orbit, except we now know that Neptune's orbit was not being perturbed, so Planet X doesn't exist. Serendipodous 09:28, 20 November 2008 (UTC)[reply]

The global differences

[edit]

Due to the climatic circumstances, the education on solar panels system should be extended accros the globe. So many people will have knowledge on it and start using it in order reduce the hydro-electrical system of poverty. Foster Opoku Akosah (talk) 08:55, 9 April 2019 (UTC)[reply]

Counter-Earth

[edit]

@Eridian314: I am strongly in favor of the inclusion of Counter-Earth here. While I am against including anything people come up with nowadays without any real justification (These are no hypotheses, these are wild ideas), the idea of counter-earth is 2500 years old, and thus of great historical significance. And for small object, it has even some merit due to the L3 point. Best regards, MGChecker (talk) 21:59, 24 February 2021 (UTC)[reply]

Theia

[edit]

Should it still be on here? Since there aren't many other alternatives to the formation of the moon Crystallyn0 (talk) 13:48, 2 March 2023 (UTC)[reply]
