Evaluation copies of SimSolar are provided at no charge, for a 30 day evaluation period. You are encouraged to pass copies of this software along to your friends and colleagues for evaluation. If you find the program useful and wish to continue using it beyond the 30 day evaluation period, payment of a registration fee is required.
Registration of SimSolar helps to fund further development of the software and provides a number of additional benefits:
Moon Phase Option - calculates the phase of the moon for any selected date and provides a photo-realistic simulation on the form.
Galilean Moons Simulator - calculates and displays the positions of the four bright moons of Jupiter for any selected date. Top-down and edge-on views are shown simultaneously, clearly demonstrating the reason for the nightly change in positions. The simulator is accurate and full-featured, providing smooth orbital motion and a wide range of controls.
Planetary Alignment Finder - detects alignments of planets from the perspective of either the sun or the earth and records them in a list. Many options are included, so that it is easy to search for alignments with the characteristics of your choice.
Planet Info Pages - shows a large picture of each planet (and also the sun and moon), and gives a general description of it, followed by a table of vital data about the planet. All pictures and data are obtained from NASA to insure quality and accuracy.
