Shh! Keep it down!
I have 2 million dollars buried in my backyard!
But it’s unknown.
It’s so unknown, I don’t even know where it is!
If life were so simple...
;-)
I think cc was quoting that part about Mercury being an escaped satellite.

“Not anymore, Monty.”
I don’t believe it I was just citing the comments at the website. Our moon is made up of the same stuff as the earth in very similar quantities and that indicates that the moon has been with the earth almost from the beginning.
Rove, you magnificent Bastard!
Or did that end with the discovery of Neptune?
Even from a Macroevolutionist viewpoint, Mercury probably isn’t a moon of Venus. It orbits the Sun normally and is in the same general plane as the rest of the non-dwarf planets (there are eight full planets in the Solar System). Also, it has a comparatively large core suggesting that it could have been larger at one time.
Xena was an acceptable name, but they went with Eris.
Shouldn’t Ceres be in the list?
It may be on the full list, but I started with the first one past Neptune, as Ceres isn’t anywhere near this hypothetical planet X. :’)
Appreciated.
I checked later, and it’s in there, between Mars and Jupiter. The other large asteroids (three of them) in the “main belt” asteroids, aren’t included, as they are not known to be spheroid as is Ceres.
“Isn’t this idea old, and a theory for why Uranus (the planet) is ‘sideways?’ Or did that end with the discovery of Neptune?”
[two months later]
Somehow missed that one. Harrington and Van Flandern theorized the existence of a planetary interloper which tore loose at least one satellite of Neptune — a satellite now known as Pluto — and tipped Uranus (heh heh heh heh), perhaps by terminal impact. Uranus’ moons orbit in the ecliptic, while Uranus axis is nearly 90 degrees out of perpendicular. TVF now attributes the tipping to an exploding planet, I believe (too lazy to check).
Update for those who are on dial-up: A spaceprobe was launched a week ago to rendezvous with Ceres and with Vesta.
Appreciated. The Dawn mission seems interesting, though with an ion drive, the probe is not set to arrive in the Asteroid Belt for some years.
37 KBOs as bright as Pluto.
