Detail Page

written by Mario Belloni

The Northern Horizon Star Motion JS model displays how the appearance and motion of the stars near and around the northern horizon change over the course of hours. The specific latitude modeled can be changed with a slider. The north celestial pole (NCP) is shown in yellow and star trails are shown in white.

The Northern Horizon Star Motion JS model was developed using the Easy Java/JavaScript Simulations (EjsS) version 5. It is distributed as a ready-to-run html page and requires only a browser with JavaScript support. This model runs on tablets.

4. The Physical Setting

4A. The Universe

K-2: 4A/P2. The sun can be seen only in the daytime, but the moon can be seen sometimes at night and sometimes during the day. The sun, moon, and stars all appear to move slowly across the sky.
K-2: 4A/P3. The moon looks a little different every day but looks the same again about every four weeks.

4B. The Earth

6-8: 4B/M5. The moon's orbit around the earth once in about 28 days changes what part of the moon is lighted by the sun and how much of that part can be seen from the earth- the phases of the moon.

11. Common Themes

11B. Models

6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.
