Harvard Scientist Proposes Earth's Orbit May Contain 35 Million Interstellar Objects

A Harvard astrophysicist has proposed a radical new perspective on the crowdedness of our Solar System, suggesting that Earth's orbit may be teeming with interstellar objects from distant star systems. Avi Loeb, known for his controversial claims about 3I/ATLAS possibly being an alien spacecraft, recently presented data indicating that roughly 35 million meter-scale interstellar objects could be embedded within Earth's orbit. This estimate, derived from the detection of two interstellar meteor candidates—CNEOS-22 and CNEOS-25—raises profound questions about the density of space debris in our cosmic neighborhood.

The two meteors, detected in 2022 over the Pacific and in 2025 over the Arctic's Barents Sea, were small, measuring about six and four feet across, yet they traveled at velocities exceeding the Solar System's escape speed. Loeb and his team calculated that such objects could collide with Earth approximately once every three years, implying a vast population of similar interstellar debris orbiting the Sun. If accurate, this suggests that Earth's vicinity is far more cluttered with interstellar material than previously assumed.

The implications of these findings are staggering. Each meter-scale object is estimated to carry about three million tons of material, and with 35 million such objects in Earth's orbit, the total mass of interstellar debris would reach approximately 220 billion tons. This mass is comparable to the contribution of larger interstellar objects like 3I/ATLAS, which are far rarer but individually more massive. Loeb theorizes that smaller interstellar objects may be fragments of larger bodies, offering a glimpse into the processes that shape planetary systems across the galaxy.

This hypothesis builds on previous discoveries, such as 'Oumuamua, the first known interstellar visitor detected in 2017, and comet Borisov, identified in 2019. These objects, along with newer findings about massive interstellar bodies, suggest that space may be filled with an
