Scientists use AI to track space junk in the Earth-Moon region
Researchers and government agencies are turning to artificial intelligence to solve one of spaceflight’s fastest-growing problems: tracking debris in the vast stretch between Earth and the Moon. With more than 100 lunar missions planned for the coming decade,

Supercomputers simulated the orbits of 1 million satellites between Earth and the moon — and less than 10% survived
If 1 million satellites were positioned at different points between Earth and the moon, less than 10% would survive long enough to be worth the hassle of sending them up in the first place, new supercomputer simulations suggest. This is not as disastrous ...
This new quasi-moon is an Arjuna asteroid — one of a cluster of more than 100 small bodies with orbits almost identical to Earth’s. These asteroids move around the Sun in almost the same orbit as Earth, with small eccentricity and minimal inclination, so that they appear to dance near us for years, indeed decades.
Some planets in our solar system have an incredible amount of moons. Jupiter has 95, with names like Ganymede and Europa. Remarkably, though, Saturn has almost three times that number, including the fast-moving Titan, with a total of 274. By contrast, our ...
Astronomers have found a space rock that has been quietly hanging around Earth for decades: a tiny asteroid named 2025 PN7. This so-called “quasi-moon” isn’t a true moon or a mini-moon, because it orbits the Sun rather than our planet. But its orbit ...
