Martian

[T]he majority of human beings born under the influence of Mars—the Martians (or "Martials")—are heavily built but physically strong. … A male Martian is generally a great favorite with the ladies and is apt to be rather quick and unscrupulous in his courtship methods. He is not a sentimental lover. A bad Martian is a loud, fatiguing talker and a braggard.

Thus she [one of the moons of Mars] has a disc, always on this assumption be it remembered, equal to about a quarter of our moon's; and being illuminated by the sun, like the other moon, with a light varying from one-half to one-third that which he pours on the earth, it follows that the light she reflects to Martians, or would reflect to them if there were any such beings, varies from one-eighth to one-twelfth of that which we receive from the full moon.
