Here you will find useful observing information about the visible planets,
our Moon and other moons, the Sun, as well as various 'things' celestial.
Among these web pages you will find monthly star maps for either the northern or southern hemisphere that are suitable for printout.
Animated images are utilized to illustrate celestial motions such as orbital motions of the planets, and other solar orbiting objects,
or apparent and real motions along the ecliptic and the local horizon. Regular features include plotting the monthly positions of the
visible planets using heliocentric coordinates; following - moon phases; conjunctions; Sun's apparent, and Earth's real
motion along the ecliptic.
