Galilean for Phones



Galilean is software to help plan and assist observations of the major four jovian satellites, also called the Galilean Moons.

Meteorites and artificial satellites excepted, nothing moves faster in the eyepiece than Io, Europa, Ganymede and Callisto. For this reason, these brightest moons of Jupiter are most popular and easy targets for binoculars and telescopes alike.

Galilean plots current and time-shifted positions of the moons, both as on-north orbit view and edge-on, while the latter can be tilted to Jupiter's rotation axis (geocentric) or parallactic angle (topocentric), if Jupiter is above horizon. Transiting moons and their shadows are plotted on an enlarged view of the planet. For curiosity, triple shadow events can be simulated from a list of occurrences between the years 1901 and 2092.

Galilean also computes detailed physical and positional ephemerides for Jupiter and the moons, as well as countdown for the transit of the GRS. Furthermore, a chart is provided showing Jupiter's elongation from the Sun.
