According to NASA, "Asteroid 2024 YR4 is now too far away to observe with either space or ground-based telescopes. The space agency expects to make further observations when the asteroid’s orbit around the Sun brings it back into the vicinity of Earth in 2028.

Scientists have confirmed the discovery of a new quasi-moon, 2025 PN7, a small asteroid that will shadow Earth’s orbit for more than a century before being pulled away by the sun’s gravity, according to a September study from the American Astronomical Society.

An asteroid just flew closer to Earth than many satellites, according to space agencies. The space object, named 2025 TF, zoomed over Antarctica at a distance of just 265 miles above the Earth's surface last Wednesday, Oct. 1, at 8:47 p.m. ET, the European Space Agency said on Monday. The International Space Station orbits at a similar altitude.

The asteroid is projected to come within 865,000 miles of Earth—nearly five times closer than the orbit of the moon.

Earth has just acquired a new best friend in space – a small asteroid named 2025 PN7. Not quite a moon, it has been moving in quiet company with our planet for decades, pacing our planet in nearly perfect synchronization as both orbit around the Sun.

Deflecting asteroids by running spaceships into them may sound like science fiction, but it's quite real. And it's quite a bit more complex than anyone thought.
