Asteroid the size of the Great Pyramid of Giza just flew (safely) by Earth

An asteroid about so long as the Great Pyramid of Giza is tall made a “close” approach with Earth on Sunday (July 25), based on NASA calculations.

There is not any fear that the space rock poses any menace to Earth, however NASA displays such rocks to each study extra about the early solar system — asteroids are rocky fragments from that point — and since if their orbits have been to vary, the asteroid may pose a future danger to Earth.

On its closest strategy, the near-Earth asteroid, referred to as 2008 GO20, swung inside 2.8 million miles (4.5 million kilometers) of our blue marble. It flew at a whopping 18,000 mph (almost 29,000 km/h), based on information studies.

The rock is estimated to be wherever from 318 to 720 ft (97 to 220 meters) throughout. (The Great Pyramid of Giza stands at 450 ft, or 138 m, tall.) Any space rock bigger than about 490 ft (150 m) throughout that’s anticipated to make a shave with Earth inside 4.6 million miles (7.5 million km) is taken into account a doubtlessly hazardous asteroid (PHA); NASA’s Center for Near Earth Object Studies displays all PHAs. For comparability, that distance is nineteen.5 instances the span between Earth and the moon.

And in actuality, that distance does not maintain a candle to the closest recognized flyby by an asteroid (at the least one that did not smash into us), which occurred on Aug. 16, 2020, when 2020 QG zipped just 1,830 miles (2,950 kilometers) above the Indian Ocean, Live Science sister web site reported. Such little space rocks pose no hazard to life on Earth.

On the different hand, 2008 GO20 is “potentially hazardous” as a result of over time the gravitational tug of the planets may change the object’s orbital path in order that it crosses Earth’s orbit. If that have been to occur, a future collision with our planet is feasible, NASA said.

This is not the first time 2008 GO20 has visited Earth’s quarters. It made its closest strategy on Aug. 4, 1901, when the asteroid swung to 806,856 miles (1.3 million km) of our planet, based on NASA data. Its subsequent closest flyby occurred on July 31, 1935 at a distance of 1.15 million miles (1.85 million km) of Earth. When it subsequent flies by Earth, on July 24, 20342008 GO20 was anticipated to get as shut as 3.1 million miles (5 million km).
