DISCLAIMER
¯¯¯¯¯¯¯¯¯¯
SOLAR SYSTEM has proven to be stable in everyday use. The author is not
responsible for any loss of data, damages to software or hardware that may
result directly or indirectly from the use of this program. The author reserves
the right to make changes to the software or documentation without notice.



WHAT IS THIS THING?
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
The object of this program is to show the orbits of planets, satellites and
comets and to move them along own orbits.



SYSTEM REQUIREMENTS
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
   Any Amiga with some memory and kickstart 1.2 or higher
   DiskFont.library
   MathTrans.library

   The ACTDM.SS file (that contains some datas) must be in the same directory
   of Solar System



FEATURES - SWITCHES
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
In the main menu there are 5 options:



1> SIMULATION

                This option allow to start a simulation. You can choose which
                planets or satellites to show (in the program: DO YOU WANT THE
                SPRITE OF PLANE... and DO YOU WANT THE SPRITE OF SATELLITE...).
                You can choose also to show the name of planets (in the program:
                DO YOU WANT THE NAME OF PLANETS?) near the sprites, to draw the
                orbits of planets and satellites (in the program: DO YOU WANT
                THE DRAWING OF ORBITS?). At the end, you can insert the time's
                interval between a position and the subsequent position (in the
                program: DAYS' INTERVAL:) and if the inserted datas are right
                (in the program: ARE DATAS RIGHT?) the simulation starts. To
                return to main menu you can press the left mouse button or the
                ESC key.



2> INFORMATION ABOUT THE PLANETS

                This option allow to get some informations of planets and
                satellites. For this it's enough insert the number of planets
                (in the program: PLANET'S CODE:). The informations that you can
                get for each planets are: MAJOR SEMI-AXIS, MINOR SEMI-AXIS,
                ECCENTRICITY, SPEED IN KM/S, RADIUS (DISTANCE BETWEEN PLANET
                AND SUN). The distance is in Astronamic Unit and the Sideral
                Period is in years. To return to main menu you can press the
                left mouse button or the ESC key.




3> SHOW LAST SIMULATION

                This option allow to show a picture of the last simulation. To
                return to main menu you can press the left mouse button or the
                ESC key.



4> QUIT
                Bye, bye!



5> QUIT AND SAVE LAST SIMULATION (ILBM)

                This option allow to save if you want (in the program: SAVE IFF
                FILE?) an IFF-ILBM picture of the last simulation before to
                quit from the program.



BUGS
¯¯¯¯
To show the pictures saved with the option number 5 "QUIT AND SAVE LAST
SIMULATION (ILBM)" you must load a graphic tool like Deluxe Paint, Personal
Paint etc..., select a 320x256 screen with 4 colors and then load the picture.
Save the pictture if you want show it with other programs (PPSHOW, FILE MASTER
etc...).
