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.

NASA confirms four asteroids, ranging from car- to house-sized, will pass Earth safely on 13–14 October 2025, posing no threat.

Siddharth Patel, a 12-year-old who lives in London, Ontario (west of Toronto), spotted two possible asteroids in September as part of a citizen science program that partners with NASA, according to the Toronto Star.

TN2, the largest of four, will safely pass Earth today at 1.34 million km. There is no threat from it, said NASA.

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.

Scientists out of the Pan-STARRs observatory in Hawaii discovered the new quasi-moon on Aug. 29, according to CNN and ABC News. It is believed that PN7 has been a quasi-moon for an estimated 60 years.
