Circumpolar Star Movement
Many folks struggle with the concept of star movement in the night sky. The fact that some stars move much faster than others, seems to compound the confusion for many. This animation, created for our sister company XplorePaks Inc., is a simulation to help middle-school students understand how star movement happens at the celestial North pole.
A circumpolar star is a star, as viewed from a given latitude on Earth, that never sets below the horizon due to its apparent proximity to one of the celestial poles. Circumpolar stars are therefore visible from a location toward the nearest pole for the entire night on every night of the year (and would be continuously visible throughout the day too, were they not overwhelmed by the Sun’s glare).
Students can select different seasons and manipulate the night sky to learn more about the movement of the night sky using a combination of buttons and direct sliders.
