Orbit : مدار

The app is an accurate interactive simulation of the solar system that allows you to explore the movement of the planets and the Moon around the Sun in a simplified, dynamic model based on real astronomical calculations.
The app uses Kepler’s equations of orbital motion to display the positions of the planets realistically, with the ability to track their changes over time live and in real time.

Features

* Realistic simulation of the motion of all planets in the solar system
* Ability to switch between a heliocentric or geocentric model
* Control the date and view planetary positions on any day
* Smooth automatic time progression
* Relative simulation of the Moon’s orbit around Earth
* Dynamic space background that reflects the depth of the universe
* Smooth performance with real-time animation updates
* Simple visual design that supports educational understanding of the solar system

Scientific Concept
The app is based on:

* Kepler’s laws of planetary motion
* Solving Kepler’s equation to determine the true position of planets
* Calculating relative orbital distances for each planet
* Simulating motion based on the number of days since the year 2000 (Epoch J2000)

Objective
This app is designed as an educational and interactive tool to help users understand how planets and the Moon move in a simple and engaging visual way, while maintaining scientific accuracy as much as possible.
