ASTR 20 Lecture Notes - Lecture 16: Luna 3, Orbital Speed, Ecliptic
Document Summary
What is intelligence: biological environmental conditions determine the rate of growth of intelligence, artificial number of neurons basically correlates with learning ability. The different phases also rise and set at different times: At full moon, the moon is opposite the sun, so its best seen from the night side of the earth-it rises at sunset, culminates at midnight, and sets at dawn. At new moon, the moon is on the same side as the sun, and so is only in the sky during the day (rises at dawn, sets at dusk) First quarter rises at noon, culminates at 6pm, and sets at midnight. Note: the moon spends as much time in the sky in daytime as at night. We see only one side of the moon. Synchronous rotation: the moon rotates exactly once with each orbit. This is why only one side is visible from earth.
