Feature Request: Add Orrery / 3D Solar System View

[Nishant040305]

It would be highly valuable to add an Orrery mode (a digital 3D Solar System view) to the app. This mode should allow users to:

• View the entire Solar System from a distant vantage point (e.g., 30 AU from the Sun)

• See accurate planetary orbits and positions

• Pan, zoom, and rotate around the Sun or individual planets

• Simulate planetary motions over time

• Optionally, provide an eyepiece/ocular simulation for observing planets as they would appear through a telescope

Rationale / Benefits:

• Provides an immersive heliocentric perspective, similar to historical orreries used by astronomers

• Supports educational and observational planning purposes

• Enhances the app’s capabilities for users interested in space navigation, planetary alignment, and Solar System visualization

• Leveraging libraries like ERFA can ensure high-precision planetary positions

Suggested Implementation:

• Implement a 3D mode toggle in the app (similar to “Occuly” or Stellarium’s Solar System view)

• Use accurate ephemerides for planetary positions and motions

• Allow camera control (orbit around Sun, follow a planet, free movement)

• Optional overlays: orbital paths, planetary labels, moons
