The Sun’s apparent motion
- The Sun’s path never changes.
- The Sun passes directly overhead at noon every day.
- The Sun rises due east and sets due west every day.
- The Sun’s path shifts towards the north during winter and shifts towards the south during the rainy season.
Celestial sphere
- The Polaris will be at the same angle below the zenith as your latitude.
- The Polaris will never change its position when looking from the Earth at a different latitude.
- Stars never move, we can see the same stars every night appearing at the same position.
- The celestial equator is a line starting from the east, passing through the zenith to the west.
- The people who live in the North Pole can observe all stars in the sky.
- The Earth is rotating clockwise about its axis.
The celestial coordinate system
- The altitude and the azimuth of stars never change.
- The right ascension and declination of stars never change when looking from different latitudes and longitude on the Earth.
- The people in any latitude can see the same stars at the same position.
Seasons
- The Earth’s distance from the Sun causes the changing of seasons.
- The Earth’s movement around the Sun causes the seasons.
- The Earth’s movement around the Sun causes the seasons.
- The Earth revolves around the Sun in an elliptical orbit. This phenomenon makes the length of days shorter in the winter and longer in the summer.
