What madness is this?
Someone found "Llama3.3-8B" source (never publicly released) in the "wild", then it was adjusted back to 128k and then I added my own special madness:
Training the model with Unsloth (3 epochs) and Claude 4.5-Opus High Reasoning dataset.
This has created an Instruct/Thinking hybrid (128k context, Llama 3.3 model).
Note this tuning was only to create an instruct/thinking model, not to update the model's core knowledge / root training.

This is a comprehensive request about orbital mechanics. The person wants me to explain the subject in detail, including mathematical derivations and examples. Let me organize this thoroughly.
I'll cover:
Fundamentals of Orbital Mechanics
Kepler's Laws
Elliptical Orbits
Orbital Elements
Vis-Viva Equation
Semi-Analytical Methods
Numerical Integration
For each section, I'll include mathematical derivations and examples.
1. Fundamentals of Orbital Mechanics
Orbital mechanics deals with the motion of objects in space under gravitational forces. The two-body problem (one object orbiting another) is fundamental.
Key quantities:
Semi-major axis (a)
Eccentricity (e)
Orbital period (T)
Gravitational parameter (μ = GM)
2. Kepler's Laws
Kepler's laws provide a framework for understanding orbital motion, derived from Tycho Brahe's observations and Newton's laws.
First Law: Law of Ellipses
An orbit is an ellipse with one focus at the center of mass of the system.
Second Law: Equal Area Rule
The line connecting the planet to the Sun sweeps out equal areas in equal times.
Third Law: Harmonies of the Spheres
There is a universal relationship between orbital period and semi-major axis.
Mathematically: T² = (4π²/GM) * a³
Or for Earth around the Sun: T² ≈ 9.95 × 10⁷ * a³
For circular orbits: v²/a = GM/r² = GM/a² = μ/a
Orbital Velocity
The velocity of an object in orbit depends on its distance from the center of gravity.
For circular orbits: v = √(GM/r)
For elliptical orbits (vis-viva equation): v² = GM(2/r - 1/a)
Orbital energy is a fundamental concept in understanding orbital mechanics. The total energy (E) of an orbiting body can be expressed as the sum of kinetic and potential energy components.
For circular orbits, the total energy is: E = -GM²/2a
This reveals the negative sign indicating gravitational binding energy that keeps the object in continuous orbit around a celestial body.
Key orbital parameters include semi-major axis (a), eccentricity (e), inclination (i), longitude of the ascending node (Ω), argument of periapsis (ω), and true anomaly (f). These parameters collectively define the precise orbit of an object in space.
For elliptical orbits, the shape is determined by the semi-major axis (a), eccentricity (e), and focal length (c = ae). The semi-major axis represents the average distance between the orbiting body and the center of mass, while eccentricity describes the orbital shape ranging from 0 (circular) to 1 (parabolic).
Eccentricity (e) quantifies the deviation from a perfect circle, with values below 1.0 indicating elliptical shapes and 1.0 or higher representing parabolic trajectories.
Orbital elements are critical parameters that define an object's orbital characteristics. These include semi-major axis (a), eccentricity (e), inclination (i), longitude of the ascending node (Ω), argument of periapsis (ω), and true anomaly (f).
Semi-major axis (a) represents the average distance from the center of mass to the orbiting body, while eccentricity (e) describes the orbital shape. Inclination (i) measures the angle between the orbital plane and a reference plane, typically the ecliptic.
Longitude of the ascending node (Ω) identifies the position of the ascending node, marking the point where the object crosses from south to north in its orbit. Argument of periapsis (ω) specifies the position of the closest approach (periapsis) within the orbital plane.
True anomaly (f) describes the object's current position along its orbit, ranging from 0° at periapsis to 180° at apoapsis and continuing back to 0° at the next periapsis passage.
Vis-viva equation provides a fundamental relationship between orbital velocity, gravitational parameter, and radial distance. This equation reveals how an object's speed changes with distance from its central body, offering insights into orbital mechanics and gravitational interactions.
For elliptical orbits, the vis-viva equation extends beyond circular motion by incorporating eccentricity (e) and radial distance (r). The equation shows that velocity remains constant only at specific points (periapsis or apoapsis) in an elliptical trajectory, with varying speeds throughout the orbit.
Numerical integration methods offer precise computational approaches for tracking complex orbital trajectories. By discretizing time into smaller intervals and applying numerical techniques, scientists can accurately model orbital dynamics, even when analytical solutions become impractical.
Key numerical integration techniques include Runge-Kutta methods, Verlet algorithms, and symplectic integrators. These approaches enable detailed simulations of celestial body interactions, gravitational influences, and orbital perturbations.

2. Kepler's Laws of Planetary Motion
2.1 First Law: Law of Ellipses
"An ellipse is described whose foci are the centers of the two bodies, and the line connecting the two bodies passes through one focus and sweeps out equal areas in equal times."
Mathematical Formulation:
Eccentricity (e): Ratio of distance from focus to vertex
e = c/a (where c = ae)
Focus Position: Focus F₁ is at a distance c from center O
Position vector: r₁ = c * (cos(θ) î + sin(θ) ĵ)
Focus F₂: At distance c from center O in opposite direction
r₂ = -c * (cos(θ) î + sin(θ) ĵ)
Proof:

2.2 Second Law: Equal Area Rule
"The line connecting the planet to the Sun sweeps out equal areas in equal times."

Simplify to show proportional relationship |
dA/dt ∝ r/v ∝ 1/r |
Geometric Interpretation:
Area swept out is proportional to time elapsed
Rate of area sweep decreases with increasing radius
