1. Summary
The NKTg Law describes the variation of an object’s inertia using the function:
NKTg = f(x, v, m), where:
•x: position
•v: velocity
•m: mass
The two central quantities of the law are:
•NKTg₁ = x × p (position–momentum interaction)
•NKTg₂ = (dm/dt) × p (mass variation–momentum interaction)
Where p = m × v, and dm/dt is the rate of mass loss over time.
This study applies the NKTg Law to analyze Neptune’s 2023 data published by NASA, thereby simulating and predicting the planet’s motion parameters for 2024 under the assumption of micro gas loss at a rate of –0.00002000 kg/s.
2. Research Objectives
Verify the predictive ability of the NKTg Law on planetary motion. •
Identify trends in Neptune’s position, velocity, and mass in 2024. •
Compare simulation results with NASA’s observed stable data trends. •

📌 Note: The NKTg simulation assumes Neptune undergoes mild gas loss at –0.00002000 kg/s, leading to a slight decrease in mass. NASA data maintains a constant mass of 1.02430000×10²⁶ kg throughout the year.
🧠 Scientific Conclusion
✅ • High Accuracy: The NKTg simulation precisely reproduces Neptune’s position and velocity per NASA’s data — with zero error in orbit and velocity; mass deviation is extremely small (~0.000020%).
🚀 • Research Value: Modeling micro gas loss demonstrates the sensitivity of the NKTg Law in simulating gas giants — paving the way for developing advanced celestial dynamics models.
🔄 • Stable Motion Cycle: Even under mass-loss assumptions, the total NKTg remains highly stable, proving the reliability of the NKTg Law in simulating complex physical behavior.
