No, a Huge Asteroid Isn't Going To Hit Earth Tomorrow

Over the past 48 hours, several apocalyptic claims have been doing the rounds, suggesting that a giant asteroid is to strike the Earth this week. Do these claims have any basis in fact?
Headlines such as "Huge asteroid is set to hit the Earth this week" have appeared online. Tweets racking up millions of views have been posted to social media indicating that a large space rock is on a collision course with our planet.
Scientists Warn Giant Asteroid Is Actually Swarm, Nearly Impossible to Destroy

It's an especially pertinent topic considering NASA's recent successful deflection of asteroid Didymos by smashing its Double Asteroid Reduction Test (DART) spacecraft into it last year, a proof of concept mission meant to investigate ways for humanity to protect itself from asteroid threats.
This Asteroid Has Survived For 4 Billion Years. That Could Be a Huge Problem : ScienceAlert

Well, maybe. But there appears to be one type of asteroid that might be particularly hard to destroy.
In our new study published today in the Proceedings of the National Academy of Sciences , we discovered that rubble pile asteroids are an extremely resistant type of asteroid and hard to destroy by collision.
Future Asteroid That Threatens Earth May Be Near-Indestructible, Scientists Warn

A future asteroid that threatens Earth may be near-indestructible, scientists concluded in a new study that offered some "aggressive" solutions for what to do if we ever face one.
Scientists who studied tiny specks of dust recovered from a potentially hazardous asteroid discovered that “rubble-pile” asteroids, which are loose conglomerations of smaller space rocks, are much more common and robust than previously assumed, a finding that suggests it might ...
Asteroid mining startup AstroForge will test its metal refinery tech in space this year • ...

Asteroid mining startup AstroForge will head to space twice this year, as it attempts to do what no other company has been able to before: unlock the potentially limitless value of precious minerals in deep space.
When TechCrunch covered AstroForge's seed round last April , we noted that the company was planning a demonstration mission sometime this year.
Will the 82-foot Asteroid 2023 BU crash into Earth?

A sneaky asteroid is on its way and it is set to make one of the closest approaches to the Earth. In fact, it will be closer to us than the satellites around the Earth.
According to the data from NASA Center for Near Earth Object Studies (CNEOS), the asteroid will make its closest approach to our planet at 2:47 AM IST on January 27. At that point, 2023 BU will be flying at the speed of 53591 kilometers per hour at a distance of 3500 kilometers above the sea ...
