SkyGlobe is a fast, fun, and easy-to-use educational
astronomy program. With it, novice and experienced
stargazers alike can view the heavens as they appear from
their own Home Town or over two hundred other locations,
and can compare a single location's celestial view from the
current date, the ancient past, and the far-off future.
Use SkyGlobe to see the effect of the Earth's 25,800-year
wobble called precession, to practice celestial navigation,
and to learn about planetary orbits.
