#### 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 2
```

In the above picture the position of Venus is shown for 28 revolutions of Mercury. Behind each position the forward angle * 1000 is shown.
• 0 is the start position. Sun, Mercury and Venus are in one line.
• 1 is the position of Venus after 1 revolution of Mercury
• 2 is the position of Venus after 2 revolutions of Mercury
• 3 is the position of Venus after 3 revolutions of Mercury. Now Venus has completed 1 revolution itself.
• 6 is the position of Venus after 6 revolutions of Mercury. Now Venus has completed 2 revolutions itself.
• 28 is the position of Venus after 28 revolutions of Mercury. Now Venus has completed 11 revolution itself.

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.

In position 1, 5, 6, 9, 10, 13 and 14 the forward angle is positive.

In position 2, 3 and 4 the forward angle is negative.

Horizontal represents the time Vertical represents the angle a of Mercury

The display consists of four values:
1. A yellow line - this line is indicated by the letter x
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

• Value 2 (Red dots around the white line) show the measured angle a after each revolution of Mercury in arc degrees.
• Value 1 (Yellow line) shows the straight line approximation of value 2
• Value 4 (White dots around the purple line) show the measured angle a in arc seconds in one century
• Value 3 (Purple line) shows the straight line approximation of value 4

The position were the two lines meet, 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.

#### 4.1 TEST 3A

for delta time of 100 seconds is between 383.0535 and 383.2555
for delta time of 400 seconds is between 366.926 and 367.1281

This result shows that the forward movement of Mercury influenced by Venus and the Earth is equal to the sum of Mercury influenced by Venus (par 3) and Mercury influenced by the Earth (par 4) i.e. 290 + 93 = 383

#### 6.1 TEST 5

The purpose of this simulation to see if and how the planets Venus, Earth, Mars, Jupiter and Saturn influences the movement of the planet Mercury.

for delta time of 400 seconds is between 532.5936 and 533.2071

Accordingly to (See Literature 7 page 198) this value should be 531 arc seconds in one century.

#### 6.2 MERCURY IN MANY CENTURIES WITH VENUS * 1.9

In this section in 2 tests the movement of Mercury is simulated.

In both tests the influence of the planets Earth, Mars, Jupiter and Saturn is simulated by making Venus 1.9 times as heavy.

In test 1 the initial distance is 69680000 km and c = 300000 km/sec This is the same conditions as figure 5 of the program Mercury.
In test 2 the initial distance is 90000000 km and c = 12000000 km/sec. This is the same conditions as figure 13 of the program Mercury.

Now perform the program: PLANETS.EXE
From the Test Selection Display
Select test 7 Subtest 29
From the Parameter Selection display

rev = revolutions of Mercury. distance in km angle 1 is in degrees. angle 2 in arc sec in one century. time in years

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
Set 4 wait time in seconds = 1

The following table compares the results

```Program PLANETS (Sun & 2 planets)            Program MERCURY (virtual planet)

```

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)

#### 6.3 MERCURY IN MANY CENTURIES WITH 5 PLANETS

rev = revolutions of Mercury. distance in km
angle 1 is in degrees. angle 2 in arc sec in one century. time in years

Time of 1 revolution

PLANETS: 14568 years
MERCURY: 14552.8 years

The results of both tests are almost identical!

In test 2 the influence of the planets Venus, Earth, Mars, Jupiter and Saturn is simulated 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

rev = revolutions of Mercury. distance in km angle 1 is in degrees. angle 2 in arc sec in one century. time in years

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.
```
