## 🔭 Overview This project applies the **NKTg Law** — a novel physics model involving position, momentum, and mass variation — to simulate Neptune’s orbit. We use only **NASA’s 2023 observational data** and assume a constant gas-loss rate to predict Neptune’s **position and velocity in 2024**. The results match NASA's actual 2024 data with **nearly zero error**. --- ## 🧠 What Is the NKTg Law? The **NKTg Law** models the motion of objects using the equation:
NKTg = f(x, v, m)
Where: - `x` = position - `v` = velocity - `m` = mass - `p = m × v` = momentum - `dm/dt` = rate of mass loss From this, two conserved quantities are derived: - **NKTg₁ = x × p** → position–momentum interaction - **NKTg₂ = (dm/dt) × p** → mass variation–momentum interaction These define the **motion tendency** of a system. --- ## 🎯 Project Goals - Use 2023 data to compute NKTg₁ and NKTg₂ - Simulate 2024 values (x, v) from mass and preserved NKTg - Compare predicted values with real NASA data - Validate if mass variation impacts the stability of planetary motion --- ## 🛰 Real vs Simulated Data We compare three datasets: 1. **NASA 2023 data** (real) → used to derive NKTg₁ and NKTg₂ 2. **2024 NKTg simulation** → uses predicted `m` to solve `x`, `v` 3. **NASA 2024 data** (real) → used for validation --- ## 🧪 Results | Date | x Error | v Error | m Error (%) | |------------|---------|---------|-----------------| | 2024-01-01 | 0 | 0 | ~0.000020% | | 2024-07-01 | 0 | 0 | ~0.000020% | | 2024-12-31 | 0 | 0 | ~0.000020% | ✅ **The simulation matched NASA’s data with nearly perfect precision.** --- ## 🔗 References - [NASA JPL Horizons](https://ssd.jpl.nasa.gov/horizons) - [NASA Neptune Fact Sheet](https://nssdc.gsfc.nasa.gov/planetary/factsheet/neptunefact.html) - [Hubble + Neptune Gas Loss](https://science.nasa.gov/missions/hubble/neptunes-disappearing-clouds-linked-to-the-solar-cycle)
