Subject: Planet 8.1
PLANET 8.1 is an application in which your Macintosh computes the
coordinates of the planets visible to the naked eye (Mercury, Venus, Mars,
Jupiter and Saturn), the sun and the moon. The coordinates are given in
different coordinate systems: the geocentric ecliptic and also the
equatorial and horizontal systems of the observer. Further you will see
the magnitude of the planets and the phase of the moon and also sidereal
time, mean solar time and the equation of time.
When a solar or lunar eclipse is possible you can also investigate the
eclipse from any place on earth. You can study heliacal risings and
settings of planets and stars and also conjunctions, planetary stations and
occultations. A special option in the program allows you to check the
visibility of the new and old moon crescent.Finally you can study the
transits of Mercury and Venus.
Included with PLANET is a small helper application, Mini Star Catalog,
containing a list of 410 bright and important stars. It is possible to
choose any star from the catalog and transfer it (one at a time) to PLANET
by drag and drop. Once the star is inside PLANET it will displayed by
coordinates updated for current precession and proper motion. Also it is
possible to study the heliacal rise and set of the star.
The program is freeware.
