Summary
The asteroid, named 2024 PT5, will temporarily be captured by Earth’s gravity. The space rock could be anywhere between 16 and 138 feet (5 and 42 meters) in diameter.
The space rock will orbit about 2.6 million miles (4.2 million kilometers) away, or about 10 times the distance between Earth and the moon.
Asteroid 2024 PT5 came from the Arjuna asteroid belt, which is made of small asteroids that have orbits around the sun similar to Earth’s orbit. Asteroid will be too small and dim for amateur telescopes or binoculars to observe.
