Interstellar Visitor Alert: NASA Tracks Third Confirmed Object From Beyond Our Solar System

Astronomers have detected a puzzling new object speeding through our solar system, believed to have originated from far beyond. The object, first observed on July 2, 2025, by the ATLAS survey telescope in Chile, has been officially designated 3I/Atlas (C/2025 N1). This marks only the third confirmed interstellar visitor, following 'Oumuamua in 2017 and comet 2I/Borisov in 2019.

Currently, the object is traveling at an incredible speed of 60 km/s and is located approximately 416 million miles from the sun. Its trajectory appears to be hyperbolic, indicating that it likely originated from outside our solar system. NASA has confirmed that the object poses no threat to Earth.

NASA Confirms Third Known Interstellar Visitor

The object, initially known as A11pl3Z, was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile. NASA and other observatories later traced its path back to June 14, confirming its hyperbolic orbit and interstellar origins. Now named 3I/Atlas, it joins a small group of confirmed cosmic wanderers, suggesting that such objects may be more common in the galaxy than previously thought. The object is currently approaching the inner solar system from the direction of the constellation Sagittarius.

Comet or Asteroid? Scientists Still Investigating

Though initially believed to be an asteroid, recent observations have revealed subtle signs of comet-like activity. The Minor Planet Center has noted a faint coma and a short tail, leading to its dual classification as C/2025 N1. Initial brightness estimates suggested a size of around 20 kilometers in diameter, but experts now believe that the dust cloud surrounding the object may be exaggerating its appearance, and the solid core is likely smaller. It is expected to reach its closest point to the sun around October 30, coming just within the orbit of Mars.

No Risk to Earth, but a Cosmic Spectacle Awaits

Despite its extraordinary origin, NASA assures that 3I/Atlas will remain at a safe distance from Earth, never coming closer than about 150 million miles. As it approaches the sun, the object may brighten and become visible through amateur telescopes in late 2025 and early 2026. The Virtual Telescope Project is planning a live broadcast for enthusiasts eager to witness this rare phenomenon. Scientists hope that studying this object will provide valuable insights into the composition and behavior of interstellar bodies.
