9. Okay, I got it. 4.25 Earth masses.

That would mean it would have 1G gravity at about twice Earth's radius.

However, with an orbital period of 17.87 days, this planet will undoubtedly be tidally locked to its star, which is a rather huge problem for life, and especially complex life, existing on it. At best, it would complicate things.

And what if it has rather high density and gravity? That would be another big issue.

However, I guess we just need to find out more about it. That's what the TMT will be for, if the ignorant assholes in Hawaii let it be built.
