Astrophysics simulation is an intricate as well as compelling process that involves several procedures. By emphasizing astrophysics simulations, we list out a few major projects, along with explicit goals and execution steps. To simulate and examine different astrophysical events, various Python libraries such as Astropy, Matplotlib, SciPy, and NumPy can be utilized by these projects.

__N-Body Simulation of the Solar System__

**Goal:** Across the impact of gravitational forces, the planet’s movement in the solar system has to be simulated.

**Execution:**

**Arrangement:**

- For planets, we have to specify preliminary positions, masses, and velocities.
- To calculate forces, Newton’s law of gravitation must be utilized.

**Equations of Motion:**

- Focus on implementing Newton’s second law: F=maF = maF=ma.
- By means of the leapfrog integration technique, the velocities and positions have to be upgraded.

**Visualization:**

- In order to visualize planetary paths, employ Matplotlib.
