SolarSystemModel

Personal project aimed for creating close-to-accurate model of a solar system with keplerian ellipse orbit🪐

Simulation examples

Orbit simulation	eclipse simulation

Overview

Primary goal

Primary goal is to create an accurate predictive model of solar eclipses, although opened to implementing more analysis tools along the way.

Dependencies

• Python 3.9.0
• Numpy 1.20.1
• Matplotlib 3.3.4
• timezonefinder 5.2.0
• pytz 2021.1
• joblib 1.0.1

Current tools

1. 2D/3D plot of solar system
   • Orbit plot
   • 2D/3D Earth-Centric/Local Celestial sphere plot
2. 2D/3D animation of solar system
3. eclipse prediction tool

Specifications

1. Configuring & Loading model info

You first need to load a model configuration info using json format. We currently only have a model config file for the Sun/Earth/Moon, but more celestial bodies can be added under 'elements' list.

Example

    {
      "name": "Mars",
      "mass_kg": 6.4171e+23,
      "diameter_km": 6779e+4,
      "orbit":{
        "center_body": "Sun",
        "e": 0.094,
        "a_km": 227.9392e+6,
        "node_lon_rad": 1.33831847,
        "incln_rad": 0.06736970913,
        "periap_ang_rad": 0.9579065067,
        "apsidal_prcs": 3233,
        "nodal_prcs": -6793,
        "anom_true_rad": 0.11195463893540733
      }
    }
