1 Earth is rotating on its own axis 1 rotation every day (24 hours) Earth is rotating counterclockwise if you are looking at its North pole from other space. Earth is rotating clockwise if you are looking at its South pole from other space.
2 Because of the Earth s rotation A W E To the lion, celestial object A is rising at East from the horizon.
3 Because of the Earth s rotation W E A To the lion, celestial object A is high in the middle of the sky.
4 Because of the Earth s rotation E W A To the lion, celestial object A is setting at the West.
5 Because of the Earth s rotation Celestial objects rise (roughly) at East and set (roughly) at West. More precisely, all celestial objects are rotating about the line joining you and the star Polaris. W E
6 Because of the Earth s rotation The motion of all celestial objects in the sky is dominated by the Earth s rotation. There is no exception, including the Sun. W E
7 Because of Sunrise and Sunset When the Sun is above horizon: Day time When the Sun is below horizon: Night time W E To the lion, the Sun is rising at the East from the horizon. Beginning of a day: approximately 6:00 a.m.
8 Because of Sunrise and Sunset When the Sun is above horizon: Day time When the Sun is below horizon: Night time W E To the lion, the Sun is rising high in the middle of the sky. Approximately Noon, 12:00 p.m (closer to 12:30 p.m. EST in Lexington, because of our location in the Eastern time zone).
9 Because of Sunrise and Sunset When the Sun is above horizon: Day time When the Sun is below horizon: Night time W E To the lion, the Sun is setting at the West. It will below the horizon after a while. Beginning of evening: approximately 6:00 p.m.
10 Because of Sunrise and Sunset When the Sun is above horizon: Day time When the Sun is below horizon: Night time W E To the lion, the Sun is at the other side of the Earth. It cannot see the Sun at all. Midnight: 12:00 a.m.
11 In summary The local time of every place on Earth is determined by the Sun position. 6 p.m. 12 p.m. 12 p.m. 6 a.m.
12 But the Moon is revolving around the Earth once every ~ 30 days. The Moon will move in the manner similar to all other celestial objects over one day time, because of Earth s rotation. However, over several days, the Moon s motion in the sky will deviate from that of other stars because of the Moon s revolution around the Earth.
13 Earth is rotating and Moon is revolving around Earth The Moon is revolving around the Earth. One revolution in about 30 days (~ 1month).
14 Both the Earth and Moon are lit by the Sun 12:00 a.m. 6:00 p.m. 12:00 p.m. Sun Light 6:00 a.m.
15 Do not worry whether the Moon and the Earth will bock sunlight from each other Earth and Moon are very small compare with Moon s orbit. Earth: Basket ball; Moon: Tennis Ball. These two balls are separated by a distance of 30 basket balls. Moon orbit is tilted at an angle of 5 o with the Earth s orbit, so they usually don t get exactly between each other. Eclipses occur when the Earth and Moon are aligned with the sun rays.
16 A realistic drawing (side view) Sun Light 5 o N When the Moon and the Earth kind of align with the sun ray, the Moon is actually way high above the Earth s shadow. Eclipses rarely occur. The dark part of the Moon we see commonly is NOT a result of Earth s shadow or lunar eclipse.
17 A Myth If that is the Earth s shadow, then this is a lunar eclipse and we will have a lunar eclipse every month! Earth s shadow cannot produce the Gibbous appearance of the Moon: This is NOT the Earth s shadow!
