# Orbital Details of our Solar System

Note: All the information provided below has been calculated by CalQlata.

The purpose of this web page is to provide the input data for our calculations on planetary spin.

CalQlata has generated the orbital details for almost all the known orbiting bodies within our solar system, the principal bodies are summarised in the Tables (below).
Fig 1 shows the diagramatic results of our calculations (excluding moons/satellites).
Whilst it is not strictly true, all the orbits have been drawn (to scale) on the same axis to aid comparison. In reality, the axes of each orbit precesses (rotates) slowly about the focus point (our sun).

## Symbols & Constants

The following symbols are used in all the Tables below.

G = Newton's gravitational constant: 6.67128190396304E-11 {m³/s²/kg}
Body Properties:
m = mass {kg}
tᵣ = rotational (spin) period {s}
ρ = density {kg/m³}
vᵣ = rotational velocity at equator {m/s}
J = polar moment of inertia {kg.m²}
Body Orbital Properties:
tₒ = orbital period {s}
a = semi-major axis of elliptical orbit {m}
b = semi-minor axis of elliptical orbit {m}
e = eccentricity of elliptical orbit
p = ½ elliptical parameter {m}
ƒ = perigee to focus {m}⁽¹⁾
x' = distance between focus and centre of elliptical orbit {m}
L = orbital length {m}
K = Newton's constant of proportionality
A = orbital area {m²}
@ Perigee
R̂ = [minimum] distance from perigee to focus {m}
F̌ = [maximum] orbital gravitational force between bodies {N}
g = gravitational acceleration at R̂ {m/s²}⁽¹⁾
v̌ = [maximum] orbital velocity {m/s}
h = Newton's constant of motion {m²/s}⁽²⁾
PE = potential energy in orbiting body {J}
KE = kinetic energy in orbiting body {J}
E = energy in orbiting body {J}⁽²⁾
@ Apogee
Ř = [maximum] distance from apogee to focus {m}
F̂ = [minimum] orbital gravitational force between bodies {N}
g = gravitational acceleration at R̂ {m/s²}⁽¹⁾
v̂ = [minimum] orbital velocity {m/s}
h = Newton's constant of motion {m²/s}⁽²⁾
PE = potential energy in orbiting body {J}
KE = kinetic energy in orbiting body {J}
E = energy in orbiting body {J}⁽²⁾
Notes for the above Table:
⁽¹⁾ Gravitational acceleration generated by the focus centre on the orbiting body at 'R̂' or 'Ř'
⁽²⁾ Newton's constant of motion (h) of the orbiting body and its energy (E) are both constant throughout orbit

All blue values are input data from from NASA's; 'Planets by the Numbers' or 'Facts Sheets'
All teal values are input data from CalQlata's website
All purple values are input data from Wikipedia⁽¹⁾
All black values are calculated using the formulas provided in our web page for Laws of Motion

## The Sun

The spin & body properties of our sun

## The Planets

CalQlata has retained the definition of the planets just as the Greeks had done; 'Wanderers', and have therefore included the largest of the so-called dwarf planets in both of the belts (Asteroid and Kuiper) that may have a noticeable affect on spin in the solar system.

The planets have been split into the following groups:
Iron [rich]
Rocky
Gas
Ice⁽²⁾

### The Rocky Planets (ρ≈3400 kg/m³)

The orbital properties of the two rocky planets in our solar system
Ceres and Pallas should have a density of between 3000 and 3400 kg/m³. Either the information about these planets incorrect, or they contain a lot more water than a normal rocky planet (e.g. Mars).

Halley's is the best understood of all our comets. The mass of the other three comets is unknown but their radii appear to be known⁽⁴⁾. Therefore, the mass of the other three comets is based upon the density of Halley's comet.

### Notes

1. Wikipedia has been used only where accurate and reliable data was not available from the NASA website
2. Ice is used here as a general term to define frozen (solid) substances that would exist as a gas or liquid on earth
3. Whilst CalQlata has analysed virtually all known moons in the solar system (including the 100 or so additional moons around Jupiter and Saturn), the vast majority are too small to be included in CalQlata's platnetary spin calculations and have therefore been omitted from this page
