HD 10180 is a good star for a Sol-type system, though. Nearly the same spectral class as our sun (orange-yellow instead of yellow), nearly the same mass, nearly the same amount of metals, and about the same temperature. But it is closer to the galactic plane than we are (galactic latitude 22.75 vs. -76.29 for the sun), so I wonder whether its "neighborhood" is as clear as ours.
The fact that HD 10180's metallicity is about 20% higher than the Sun's indicates it's a younger star. Perhaps in a few millions years all these hot Jupiters and such will spiral into their sun or clear the inner system out, and then there will be room for a planetary collision or two to make some terrestrial planets. But that's too long to wait.
Correct me if I’m wrong, but since a star other than Sol is involved, it can’t be a “solar” system, can it?
