A giant asteroid almost hit earth on September 16 but because it came from the direction of the sun, scientists missed it.

If you heard a whooshing noise recently, you weren’t imagining it—there was indeed a gigantic asteroid that almost hit earth this month. And NASA didn’t see it coming.

The asteroid, named 2021 SG, has a diameter of around 42 to 94 m, with a diameter or around 68 m, which makes it around half the size of the great pyramids.

The asteroid tracker EarthSky has it listed for September 16 but NASA only detected it a day later.
