Hypothetical Planets - Neatorama

Throughout history, astronomers have observed heavenly bodies or some evidence of them that later “vanished”. Or did they? Hypothetical planets include:

* Vulcan, the intra-Mercurial planet
* Mercury's Moon
* Neith, the Moon of Venus
* The Earth's Second Moon
* The Moons of Mars
* The 14th Moon of Jupiter
* Saturn's Ninth and Tenth Moons
* Six Moons of Uranus
* Planet X
* Nemesis, the Sun's companion star
* References

I can imagine having two Moons for the Earth. I'm sure we'd be experiencing longer nights or rather more likely more night like phases. However, the Sci-fi junkie in me is wondering how cool it would be to see two Moons in the sky...regardless of the pull on the tidal waves! ;)

Moons don't give you nights. Suns give you days. When you don't see sun, you have night.

@ Thai

If there was another moon we may end up with an Eclipse like setting which plunges people into a "night-like" setting.

Only 14 moons on Jupiter?

you know, if you shrunk the solar system down to scale with Pluto touching your toes and Mercury at the top of your head, Uranus is exactly where you'd think it would be.

One minute - why isn't Pluto on that list? It was thought to be a planet, but then taken away.
Anybody else miss it?

Pluto isn't a 'hypothetical planet', it's a classified 'dwarf planet'. Pluto's existence is not a theory, thus 'hypothetical' doesn't apply as an adjective.
