Which horizon does the sun rise

Actually, the Sun only rises due east and sets due west on 2 days of the year — the spring and fall equinoxes! A tmospheric refraction makes the Sun visible even when it is just below the horizon. As you may know the international date line is as crooked as the contents of a badly packed suitcase, and Samoa, once known as the last place to see the sun set, is now the first place on the planet you can see the sun rise. The Sun appears to rise above the horizon and circle the Earth, but it is actually the Earth that is rotating, with the Sun remaining fixed.

This effect results from the fact that an observer on Earth is in a rotating reference frame. Occasionally a false sunrise occurs, demonstrating a very particular kind of Parhelion belonging to ….

Advanced The sun appears to rise on the eastern horizon and sets on the western horizon. Semantic enigmas. The body beautiful. Red tape, white lies. Speculative science. This sceptred isle. Root of all evil. Ethical conundrums. This sporting life. Stage and screen. And imagine that the outside rim of the disk represents your horizon.

On Summer Solstice, you would see the Sun rise on your "horizon" at the eastern point of the longest track. It would follow the track high in your sky, and eventually set on the western horizon. It would be up for about 17 "hours", thus making summertime days long and warm. On the Winter Solstice, you would observe the Sun rising at the western end of the smallest track. It wouldn't rise high in the sky, and would be up for only about 6 or 7 hours, making your days short on daylight and cold.

At the Spring and the Fall equinoxes, the Sun would rise at the east end of the middle track and set at the west end. Build your own Sun Track Diorama What about the stars? The rising points of the stars don't change as much as the Sun's because they are so very far away.

So the rising points of stars on the horizon were not as critical to ancient cultures. However, the rising times of stars change by 4 minutes each day, so any particular star would rise at different times during the year. For about half the time, the star would rise during the daytime and thus be blocked by the huge light of our Sun.
