As of late 2025, NASA had confirmed the existence of a temporary second moon that would remain in orbit next to Earth until 2083. Astronomers discovered a "quasi-satellite" of Earth, also known as a ...

Earth's cosmic neighbourhood is more dynamic than imagined, hosting temporary 'mini-moons' captured by gravity and ...

Researchers used a pair of powerful supercomputers to simulate the potential trajectories of 1 million satellites in a cislunar orbit between Earth and the moon. Less than 10% of these orbits remained ...

Astronomers have spotted a quasi-moon near Earth — and the small space rock has likely been hanging out near our planet unseen by telescopes for about 60 years, according to new research.Related video ...

The object is called 2025 PN7, and it was spotted on Aug. 2, 2025, by the Pan-STARRS telescope in Hawaii. Even though it was just discovered, earlier data shows it's been in this unusual orbit for ...

Astronomers recently detected a stray quasi-moon in our planet’s orbit, but it's hardly the first stowaway to hang out around Earth. Unlike the Earth's moon, quasi-moons are not gravitationally bound ...

For more than 25 years, humans have lived and worked continuously aboard the International Space Station, conducting research that is transforming life on Earth and shaping the future of exploration.
