Orbital Analysis Confirms Interstellar Origin of 3I/ATLAS

After months of precise observations and calculations, astronomers have definitively confirmed that Comet 3I/ATLAS originated from beyond our solar system.

The Evidence

The comet's orbital eccentricity of 6.3 clearly indicates a hyperbolic trajectory, meaning it will never return to our solar system after its current visit.

Comparison with Previous Visitors

  • 'Oumuamua (1I): First confirmed interstellar object, asteroid-like
  • Borisov (2I): First interstellar comet, similar composition to solar system comets
  • 3I/ATLAS: Third visitor, showing unique characteristics

This discovery opens new possibilities for studying the composition of objects from other stellar systems.
