An asteroid wider than two football fields will zoom past Earth in the wee hours of Thursday (Aug. 4). The asteroid is set to pass at 12:23 a.m. (ET).NASA astronomers discovered the
asteroid, known as 2022 OE2, just days ago, on July 26. The meaty space rock is estimated to measure between 557 and 1,246 feet (170 to 380 meters) wide, which is about twice as wide as an American football field is long. Astronomers also confirmed that 2022 OE2 is an Apollo-class asteroid, which means it orbits the sun and crosses the path of
Earth's orbit,
Live Science previously reported. (Astronomers know of about 15,000 such asteroids.)
The impact from an asteroid this large would release more energy than 1,000 nuclear bombs. However, this one will miss Earth by a wide margin,
according to NASA's Jet Propulsion Laboratory.
Asteroid 2022 OE2 is predicted to pass Earth at a distance of roughly 3.2 million miles (5.1 million kilometers) — more than 13 times the average distance between Earth and the
moon. For context, this is significantly farther than the
asteroid 2022 NF, which came within a mere 56,000 miles (90,000 km) — or about 23% the average distance between Earth and the moon — on July 7.
