Sol has a sibling.

Not of the sciency goodness, but definitely amusing.
A good place to look for signs of life I would think.
Same make up, same age, same galactic orbit.

It's in Celestia: HIP 97507 = HD 186302

Yes, it is in Celestia, but it is a type G3 star rather than G2.

Is possible to override the type via an extra, just like we do with any SSC file?

Code: Select all
Modify 97507 { SpectralType "G2V" }

THANKS A LOT!
Added after 3 minutes 44 seconds:Anyway i created
a GH issue addressing this (althrough
in Wikipedia they also say this star is a G3, dunno what is correct).

I'm think it's G3/5V. Solar twins don't necessarily have to be G2V (see
the list on Wikipedia for an example). Although an exact solar twin would have the exact parameters as the Sun, this is unlikely because no two stars are identical. Also,
SIMBAD and
all the other sources in VizieR say that the spectral type is G3/5V or some variation of that. (Maybe they just copied from the HD catalogue, but that's a different problem.)
