2025 PN7 is a small, dim asteroid that appears to orbit Earth, according to EarthSky. Believed to be a piece of the moon that blasted out, the object has been in its orbit as a quasi-moon for about 60 years and is expected to continue for another 60 years or so years before drifting away.

Scientists have long debated whether dinosaurs were in decline before an asteroid smacked the Earth 66 million years ago, causing mass extinction. New research suggests dinosaur populations were still thriving in North America before the asteroid strike, but it’s only one piece of the global picture, independent experts say.
