📖 How to read this chart
Sun (yellow): The center of our solar system. All distances are measured from here.
Planetary orbits (gray circles): Shown for scale. Earth is at 1.0 AU (Astronomical Unit = Earth-Sun distance, ~150 million km).
Object trajectory (orange line): The path this interstellar object took/will take through our solar system. Notice it's not a circle - it's hyperbolic!
Current position (blue pulsing dot): Use the time slider to see where the object was or will be on any date.
Controls: Zoom in/out with buttons, pan by clicking and dragging, scrub through time with the slider.
