Description:
This collection of animations introduces students to planetary motions, gravitational effects, and the scale of astronomical distances. Students can view visualizations of Earth's changing seasons, circumpolar motion, and the celestial equator and ecliptic plane. Animations on gravity explain how satellites orbit, the motions of comets and meteor storms, and gravitational 'warping'. Other animations explain how Earth's tides are produced, how astronomical distances are calculated, the use of spectra in astronomy, and the lifecycles of stars.
