The innermost planet is as a wise kerbal who sun-bathed too much and then got splashed by their grandchildren. Actually, that's not very wise, now is it? ...Moho has seen a lot and taken more punishment than the other local planets, so it appears. Look at those streaks! Think of what Moho might be secretly carrying now! And think of the heat too!

Moho's shares the following with the real planet Mercury: Orbital period, Rotational period, Eccentricity, Inclination. With Rational Resources installed, it also shares a mine-able trace atmosphere and pockets of water or hydrates near the poles.
