For more than sixty years, a tiny asteroid has been moving in step with Earth, hidden from view until recently. Astronomers now confirm that this small body, named 2025 PN7, is traveling in a special ...

Unlike the Moon, which is gravitationally bound to our planet, 2025 PN7 shares an orbit around the Sun that closely mirrors ...

Earth still only has one true natural satellite — our 2,159-mile-wide moon oribiting about 239,000 miles away. However, ...

Named after the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey that first detected it, 3I/ATLAS includes the “I ...

NASA has confirmed a new cosmic tag-along: asteroid 2025 PN7, a “quasi-moon” orbiting the Sun in sync with Earth. This tiny ...

Quasi-moons are not real moons and don't actually orbit the Earth, although they sometimes appear to do so for short periods of time, Phil Nicholson, professor of astronomy at Cornell University, told ...

The concept, also depicted in a Star Trek episode, would fill Earth's orbit with satellites to harness energy from the Sun and block out solar rays to help cool the climate.

Astronomers say that Earth is going to get something new in the coming decades. The recently discovered asteroid 2025 PN7 has ...

The tech industry is on a tear, building data centers for AI as quickly as they can buy up the land. The sky-high energy costs and logistical headaches of managing all those data centers have prompted ...

NASA’s Kepler spacecraft has spotted an Earth-like planet orbiting around a Sun-like star found in a habitable zone most similar to our own. The exoplanet, Kepler-452b, was found 1,400 light-years ...

CAPE CANAVERAL, Fla. -- For the first time ever, astronomers have discovered seven Earth-size planets orbiting a nearby star - and these new worlds could hold life. This cluster of planets is less ...

The European Space Agency's Proba-3 mission utilizes two spacecraft to create an artificial solar eclipse, enabling observation of the Sun's corona, which is typically obscured by the Sun's brightness ...
