Main Document

Star Motion on the Horizon JS Package 

written by Mario Belloni and Kristen Thompson

The Star Motion on the Horizon JS Package displays how the appearance and motion of the stars near and around the northern, southern, eastern, and western 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 Star Motion on the Horizon JS Package was developed using the Easy JavaScript Simulations (EjS) version 6.  It is distributed as a ready-to-run html page and requires only a browser with JavaScript support.  This model runs on tablets.
