Owing to the action of the moon on the earth, as it performs its monthly revolution in an orbit slightly inclined to the ecliptic, the centre of the earth itself deviates from the plane of the ecliptic in a period equal to that of the nodal revolution of the moon.
He sought to determine the distance and magnitude of the sun, to calculate the diameter of the earth and the influence of the moon on the tides.
Kiera tugged at the moon on her necklace as she walked down the hall toward the video game room.
