Asteroid Bigger Than Egypt’s Great Pyramid of Giza Barely Misses Earth
An asteroid about 100 meters in diameter has become the largest known asteroid to flyby Earth within 1 lunar distance since the start of the year.
The newly discovered asteroid dubbed “2019 OK” flew by Earth at a distance of just 70,000 kilometers (43,496 miles) at 11:22 a.m. on 25 July 2019. The asteroid reportedly flew at a speed of about 24 kilometers a second.
According to NASA, the object is nearly two-times taller than the Great Pyramid of Giza in Egypt and 2.7-times as tall as the Statue of Liberty in New York and is also about 2.5-times taller than Big Ben in London.
