1 INTRODUCTION

The purpose of this program is to simulate the movement of different the planets around the Sun.
The following combinations are studied:
  1. Mercury around the Sun
  2. Mercury and Venus around the Sun
  3. Mercury and Earth around the Sun
  4. Mercury Venus and Earth around the Sun
  5. Mercury and all the planets except Pluto
  6. Galaxy Sun AND Mercury.

The following conditions (parameters) are studied:
  1. Virtual Planet concept
  2. The movement of the Sun through space.
  3. The speed of gravity propagation

The simulation is done assuming that all the planets move in one plane. The program PLANET3D takes into account that the plane of Mercury is tilted.

1.1 VIRTUAL PLANET

The results of the tests 2, 3 and 4 (discussed in the paragraphs 3, 4 and 5) show that the planet Mercury is influenced by all the planets. The problem is that this influence is highly "irregular" and takes many years to settle down.

The concept behind the virtual planet is to replace all the planets by one planet in such a way that the influence of this virtual planet is the same as all the planets.

The virtual planet is a planet which moves at the same distance as Venus The position of the virtual planet is such that the Sun, Mercury and this virtual planet are always in one line. That means Mercury is always in-between the Sun and the Virtual Planet. The mass of this planet is a function of the distance of Mercury and the Sun.

Figure 1 shows:

one string of white dots
two strings of red dots.

The string of white dots represents the angle in arc sec in one century for phi between 0 and 360 in increments of 15 degrees
For phi between 55 and 305 the angle is positive i.e. a forward movement.

The maximum is at phi = 180 degrees.
For phi from 0 to 55 (and from 305 to 360) the angle is negative i.e. a backward movement.

The two strings of red dots represent the difference in distance after one and two revolutions of Mercury for phi between 0 and 360 in increments of 15 degrees.
For phi between 0 and 180 the distance becomes smaller. Maximum is at phi is 90.
For phi between 180 and 360 the distance becomes larger. Maximum is at phi is 270.

In the above picture the position of Venus is shown for 28 revolutions of Mercury. Behind each position the forward angle * 1000 is shown.

Figure 2 shows that there are two areas (one around position 0 and one around position 1) that the forward angle is positive.
In two other areas (one around position 3 and one around position 17) the forward angle is slightly negative.

The area around position 0 shows the position of Venus when Venus and Mercury are close together (at the same time).

The area around position 1 shows the position of Venus when Venus and Mercury were close together at the beginning of the revolution of Mercury.

In the other areas Mercury and Venus are during one revolution of Mercury never close together.

  2. Red dots around the yellow line
  3. A purple line - this line is indicated by the letter y
  4. White dots around the purple line

The position were the two lines meant indicate one century.

The value for the forward movement of Mercury influenced by Venus in arc seconds in one century is:

for delta time of 50 seconds is between 289.809 and 290.0753
for delta time of 100 seconds is between 289.0028 and 289.2692
for delta time of 400 seconds is between 272.8768 and 273.1433

This means if you want to do an accurate simulation delta time has to be at least 100 seconds or less.

Time of 1 revolution

PLANETS: 14672.2 years
MERCURY: 14552.8 years

The above results show that the influence of the planets Earth, Mars, Jupiter and Saturn initially can be simulated by making Venus 1.9 times as heavy, but becomes less accurate for shorter distances from the Sun.

In test 2 the influence of the planets Earth, Mars, Jupiter and Saturn is simulated by making Venus 1.9 times as heavy (i.e. identical as test 1) but now compared with the same conditions as figure 13 of the program Mercury. In figure 13 the initial distance is 90000000 km and c = 12000000 km/sec.

Now perform the program: PLANETS.EXE
From the Test Selection Display
Select test 7 Subtest 33
From the Parameter Selection display

The following table compares the results

The above results show that the concept to simulate the influence of the planets Earth, Mars, Jupiter and Saturn, by making Venus 1.9 times as heavy, is not accurate and that a more complex model is required (assuming that the virtual planet concept is correct, which is the subject of the next test)

The results are almost identical meaning that the virtual planet concept is a very good (and practical) substitute for 5 planets Venus, Earth, Mars, Jupiter and Saturn.

The big improvement is speed of the simulation.
One revolution of Mercury with program (delta time = 400): 

        PLANETS with Venus * 1.9    takes about 10 seconds. 
        PLANETS with 5 planets      takes about 50 seconds. 
        MERCURY with virtual planet takes about 4 seconds.
