Harvard scientist Avi Loeb has claimed that there could be 35 million interstellar objects inside Earth's orbit. In 2025, 3I/ATLAS, the third known interstellar object, was discovered in the solar system and became the star of the astronomy world overnight. But Loeb has presented calculations, according to which objects from the outer world are extremely common. He studied two meteors that probably came from another star system to estimate the number of interstellar objects in our solar system. CNEOS-22 was detected in 2022 over the Pacific, and CNEOS-25 was spotted over the Barents Sea in the Arctic in 2025. They were both around six feet and four feet across, but large enough to exceed the Solar System's escape velocity. Loeb stated that such meteors collide with Earth on average once every three years. Using this premise, he concluded that these objects exist in large numbers in Earth's orbit.&nbsp;"Given the detection of two interstellar meteors in the CNEOS fireballs database over a period of 7 years, the inferred collision rate of meter-scale interstellar objects with Earth is about 0.3 per year," Loeb wrote. He added, "This implies that there are about 35 million meter-scale interstellar objects embedded at any time within the orbit of the Earth around the Sun." The scientists calculated that each object carries about 3 million metric tons of material, which means that "hundred trillion (10^{14}) metric tons of interstellar material is present" in the interior of Earth’s orbit around the Sun.Also Read: <a href="https://www.wionews.com/trending/3iatlas-latest-update-nasa-tess-images-jupiter-1769745274633">NASA's TESS captures 3I/ATLAS once again.

Scientist claims 35 million interstellar objects reside between Sun and Earth - '100 trillion metric tons...'

3I/ATLAS is a recently discovered interstellar comet, which is a visitor from another star system. It was discovered by the ATLAS survey and is the third interstellar object ever detected.
