The fly-by will be completely safe and poses no risk to anything or anyone on Earth or any of our satellites. But asteroid 2021 EQ3 will come closer to Earth than our lone natural satellite.
Sky surveys and other telescopes spot a space rock passing closer than the moon every few days, on average. Most of these asteroids are just a few meters across, likely making them no larger than a bus.
2021 EQ3 will pass closest above us at roughly 9:45 p.m. PT Monday night, at a distance of around 173,000 miles (278,000 kilometers) -- that's 72% of the distance from the Earth to the moon.
This may worth something:
Asteroid dust found at Chicxulub Crater confirms cause of dinosaurs' extinction |
Fast forward to the 1980s, and scientists uncovered traces of asteroid dust, finding it scattered around the globe within the same geological layer that corresponds to the dinosaurs’ extinction. In the following decade, Chicxulub Crater was discovered in the Gulf of Mexico. And because the crater appeared to be the same age as the global rock layer enriched with asteroid dust, researchers were fairly certain they had the story of the dinosaurs’ demise figured out.

The asteroid belt: Wreckage of a destroyed planet or something else? | Astronomy.com
But how was this orbiting field of debris formed? Does it represent the rocky bones of a former planet from eons past, or is it a type of gathering place for a planet-to-be?
Scientists have considered both responses as possibilities over the decades. But more recent theories contend that the vast ring of space rocks likely never was a whole planet and is unlikely to be so in the relatively near galactic future. Why? There simply isn’t enough material there.
Quite a lot has been going on:
The story of Trojan asteroids - The Hindu

Trojan asteroids are asteroids that share an orbit with a planet and are located at the leading (L4) and trailing (L5) Lagrangian points of the planet's orbit. Lagrangian points or Lagrange points are locations in space where the combined gravitational forces of two large bodies, such as the Earth and Sun, equals the centripetal force required for a small object to move with them.
A Japanese spacecraft bombed an asteroid and it barely flinched | New Scientist
In 2019, Japan's Hayabusa 2 spacecraft bombed the asteroid Ryugu, using explosives to shoot it with a 2.5-kilogram lump of copper to create an artificial crater. Scientists expected this impact to shake the ground, but its actual effect was far milder.
Hayabusa 2 images have shown that the surface of Ryugu has fewer small craters than we'd expect for an asteroid of its size, which probably indicates that dust is being moved somehow to fill in those craters. Asteroids do not have significant atmospheres, …

Incredibly Rare Asteroid Fragments Land on Couple's Driveway
The space rocks landed near the home of Rob and Cathryn Wilcock in Winchcombe, England on February 28 after a fireball was spotted hurling across the skies above the western UK region, according to The Smithsonian Magazine .
The couple heard a rattling noise that night but couldn't see what it was in the dark. It wasn't until the next morning that they discovered a small pile of black rocks and dust on their driveway. They later sent photos of their find to researchers at the Natural History Museum in London who had put out a call for fallen pieces of meteorite.
