Alien mothership 3I/ATLAS could reach Earth in just 113 days, says Harvard professor. Will it bring salvation or destruction?

Alien mothership 3I/ATLAS, travelling at 135,000 mph, could reach Earth between November 21 and December 5, 2025, as per a Harvard professor. The expert claims the object is not an interstellar comet but an alien spacecraft or mothership. The unidentified object is travelling towards Earth and is expected to arrive in just 113 days. Harvard professor Avi Loeb has suggested it could be an alien spacecraft, raising global interest and debate among scientists.

Alien Mothership 3I/ATLAS Discovery

3I/ATLAS was first spotted on July 1, 2025. Astronomers noticed it travelling through the solar system at high speed. It is only the third interstellar object ever detected in our solar system. Scientists initially believed it to be a comet or a large piece of space matter.

Alien Spacecraft Theory by Harvard Professor

Professor Avi Loeb has proposed that the object might be of technological design rather than natural origin. He compared it to Arthur C. Clarke’s science fiction novel Rendezvous with Rama, where a foreign object in space turns out to be an alien ship. Loeb believes 3I/ATLAS could be a mothership carrying probes or other devices.

Alien Mothership 3I/ATLAS Predicted Arrival and Speed

Loeb estimates that 3I/ATLAS could reach Earth between November 21 and December 5, 2025. It is currently travelling at about 135,000 miles per hour. According to NASA, it will reach its closest point to the Sun on October 30, 2025, around 130 million miles from Earth.

Alien Mothership 3I/ATLAS Size and Unusual Characteristics

Scientists have not been able to measure the exact size due to the object’s distance. Estimates suggest it measures between 20 and 24 kilometres across. This makes it far larger than the previous interstellar object detected, which was only about 100 metres long. Loeb has highlighted the unusual size and direct path towards the inner solar system as reasons for further study.

3I/ATLAS NASA and ESA Statement

Both NASA and the European Space Agency have classified 3I/ATLAS as an interstellar comet. They say its path and behaviour match known patterns for such objects. Loeb accepts this as the simplest explanation but maintains that more investigation is needed to rule out the possibility of advanced technology.

3I/ATLAS Disagreement Among Experts

Not all scientists agree with Loeb’s theory. Chris Lintott, an astronomer at the University of Oxford, has called the alien probe idea “nonsense” and said it undermines research into the object’s true nature. Other astronomers stress that extraordinary claims require extraordinary evidence.

Alien Mothership 3I/ATLAS Possible Risks and Preparations

Loeb has warned that if 3I/ATLAS is an alien vehicle, it could be friendly or hostile. It might carry technology meant to help humanity, or it could pose a danger. He suggests that all interstellar objects should be studied carefully to confirm they are natural.
