NASA is monitoring a bus-sized asteroid that set to zip past the Earth at some 15,200 miles per hour.

The asteroid—"2025 PY1"— will make its closest approach at just 183,000 miles from our planet, according to the space agency's Jet Propulsion Laboratory (JPL).

The space rock is estimated to be somewhere between 25–55 feet in diameter, according to the JPL's Center for Near-Earth Object Studies (CNEOS).

2025 PY1 is not the only asteroid that will be in the vicinity of our planet today; NASA is also tracking a plane-sized asteroid known as "2025 PB2," which is around 99 feet in diameter, as well as a house-sized one called "2025 QC," which is about 61 feet in diameter.

2025 PB2 is due to make its closest approach at around 1.34 million miles from the Earth, while 2025 QC will only get
