-This project combines a raytracer and an N-body solar system simulation to learn modern C++ (C++03–C++23) through practical implementation.
+This project combines a raytracing in one weekend style raytracer and an N-body solar system simulation to learn modern C++ (C++03–C++23) through practical implementation.
 
 * ✅ Project Goals
-- [ ] Simulate solar system using an N-body gravitational algorithm.
-- [ ] Implement a raytracer for rendering bodies and backgrounds.
+- [X] Simulate solar system using an N-body gravitational algorithm.

-- [ ] Unit tests for vector math and physics (can use C++11 `assert`)
-- [ ] Visual verification of orbits and raytraced scene
-- [ ] Compare numerical stability over long time steps
