Simulation and 2D visualization of a planet's orbit in Python
Python
Successfully completed a commercial project on the calculation and astro-visualization of a space trajectory. What was done: A clean script was written in Python 3 for physical and mathematical calculations. Processing of coordinate arrays was implemented using the NumPy library. An interactive 2D graph of the planet's orbit around the star was built using Matplotlib. Custom markers were set up for the stellar center (the Sun) and key positions of the object. The code is fully adapted for running in Google Colab and local environments (VS Code). The work was delivered on time, and the client is completely satisfied with the result. #python #data-science #matplotlib #numpy #programming #scripts
