The asteroid will zoom safely past Earth at 47,200 miles per hour.
The near-Earth asteroid 7,335 (1989 JA) will make a close approach to our planet on May 27, 2022, flying within about 2.5 million miles of Earth.
The end, when it came, came suddenly. An asteroid or comet 10 kilometres across slammed into the Gulf of Mexico, gouging a 180-kilometre crater and unleashing firestorms, eruptions and mega-tsunamis across the globe. The debris blocked out the Sun for years. The dinosaurs – and the other 75 per cent of life that went down with them – didn’t stand a chance.
The story of the demise of the dinosaurs 65 million years ago is well known. But that of their origin is less so. Dinosaurs were the dominant animals on land for at least 135 million years, the longest reign of any group. Had the impact not happened, they might still be in control. Where did these magnificent beasts come from?

The Tanis fossil site located in North Dakota in the United States of America is currently one of the most interesting places on Earth. Well that’s if you like dinosaurs and uncovering the ancient mysteries of our planet. Maybe you’re more into ancient computers that predict eclipses (opens in new tab). If not, uh, why not check out some of our hot Elden Ring content (opens in new tab)? We’ve got guides on the best builds (opens in new tab), how to survive (opens in new tab), and all sorts of stuff.
Ok, now that we’ve gotten rid of those people, back to the dinosaurs.
Earthlings 800 years from now can breathe a little easier.
A fresh assessment of a distantly risky asteroid brings good news: it’s even less of a threat than astronomers had feared.
The chances of an asteroid dubbed 1950 DA crashing into Earth were always tiny and long in the future: As of 2015, scientists had calculated that the object had a 1 in 8,000 chance of impacting Earth in the year 2880. But a new analysis released on Tuesday (March 29) knocks the asteroid out of the top spot of NASA’s list of known asteroids that are most potentially hazardous to Earth.

ATLAS has already spotted more than 66 comets and 700 near-Earth asteroids (two of which actually hit Earth’s atmosphere!).
READER QUESTION: If humans don’t die out in a climate apocalypse or asteroid impact in the next 10,000 years, are we likely to evolve further into a more advanced species than what we are at the moment? Harry Bonas, 57, Nigeria
Humanity is the unlikely result of four billion years of evolution.
From self-replicating molecules in Archean seas, to eyeless fish in the Cambrian deep, to mammals scurrying from dinosaurs in the dark, and then, finally, improbably, ourselves—evolution shaped us.
By the time our planet was four billion years old, the rise of large plants and animals was just beginning. Complexity exploded around that time, as the combination of multicellularity, sexual reproduction, and other genetic advances brought about the Cambrian explosion. Many evolutionary changes occurred over the next 500 million years, with extinction events and selection pressures paving the way for new forms of life to arise and develop.
65 million years ago, a catastrophic asteroid strike wiped out not only the dinosaurs, but practically every animal weighing over 25 kg (excepting leatherback sea turtles and some crocodiles). This was Earth’s most recent great mass extinction, and it left a large number of niches unfilled in its wake. Mammals rose to prominence in the aftermath, with the first humans arising less than 1 million years ago. Here’s our story.
