    The asteroid, called "2019 OK," passed about 40,400 miles above Earth's surface — roughly 5 times closer to Earth than the moon — at 55,000 miles per hour and could have "created localized devastation to an area roughly 50 miles across" if it struck land, according to a NASA news release. "An asteroid of this size coming this close to Earth is a pretty rare event — on the order of about twice a century," according to Paul Chodas, manager of NASA’s Center for Near-Earth Object Studies at JPL.

    AN ASTEROID which came crashing into Earth and NASA had no idea it was coming reiterates the need to keep a closer eye on the sky in case a massive space rock comes hurtling towards our planet. A small asteroid shot towards Earth at 14.9 kilometres per second, and NASA admitted it did not know it was coming. The space rock known as 2019 MO was just three metres wide and exploded when it hit the planet’s atmosphere on 22 July above the Caribbean, but the way it approached unexpectedly reaffirms the need for more eyes on the sky.

    Asteroid 6478...Gault was discovered last December and labelled as an active asteroid that left not one, but two trails behind it, just like a comet. Now, the same asteroid has been caught switching colours, from red to blue in near-infrared spectrum by astronomers at the Massachusetts Institute of Technology (MIT), United States. This is the first time in the history of extraterrestrial materials that that astronomers have seen any shift in colours in an asteroid. Gault now glows in a blue tinge as a result of a less irradiated layer of the asteroid coming to light. According to the study’s...

    Earth was born as a result of repeated asteroid collisions, the moon was created by a single giant impact event. Then, Earth's size attracted huge meteorites, which slammed into it, causing super-high-temperature rock vapour to cover the entire surface and evaporate all ocean water. The earliest life-forms survived such infernal events by escaping deep into the ground, miraculously emerging again and again. The Earth has gone through innumerable catastrophic events, and life has survived by acquiring new abilities to live through each crisis. Humans are part of the grand history of life's evolution, which has been closely intertwined with repeated...

    A metal asteroid worth $10,000 quadrillion, hurtling through space, makes construction of a massive orbital space station substantially cheaper. At least one company is already pitching a plan for a Von Braun Gateway Station housing some 1,500 people in orbit. The resources on the single asteroid, 16 Psyche, is not only enough to build the station, but to wipe out the U.S. national debt thousands of times over.

    — Elon Musk, CEO of SpaceX and Tesla, tweeted that a "big rock" is going to hit Earth, and that we "currently have no defense." But NASA, seems to disagree. Musk's tweet was a response to another by comedian and podcaster Joe Rogan, who shared an article reporting that NASA has begun preparations for the 1,100-foot-wide asteroid Apophis, which is scheduled to pass by Earth on April 13, 2029. Apophis named after an Egyptian god of death. Musk isn't wrong when he tweeted "Wouldn't worry about this particular one," though. Apophis is going to miss us by 19,000 miles. It's...

A NASA mission has spent over 8 months sizing up the massive asteroid Bennu, located between Earth and Mars, to finally select four areas on its surface as possible sampling sites for its OSIRIS-REx spacecraft to grab a piece...

On Thursday, the astronomer's phone was suddenly flooded with calls from reporters wanting to know about a large asteroid that had just whizzed past Earth, and he couldn't figure out "why everyone was so alarmed." "I thought everyone was getting worried about something we knew was coming," Duffy, who is also lead scientist at the Royal Institution of Australia, told The Washington Post.

    We weren't in danger of losing a chunk of our planet to asteroid 2019 OK, but it was detected just the day before it slipped past, and that's the worrying part. The European Space Agency had enough time to ask two telescopes in the International Scientific Optical Network (ISON) to take a look at the asteroid right before its flyby. These aren't beauty shots. The asteroid looks like a dark blob, but the observations are helping us learn more about 2019 OK. We now know the asteroid flew by at a distance of just 40,000 miles (65,000 kilometers). Cosmically, that's...

    The space rock — designated as a near-Earth object, because its orbit takes it within 30 million miles of our planet — is expected to come within about 4.55 million miles of us as it whizzes by at 10,400 mph. Anything that gets closer than 0.05 “astronomical units” — roughly 4.65 million miles — is considered “potentially hazardous.” The asteroid, dubbed 2006 QQ23, is 1,870 feet in diameter

    Three asteroids will pass safely by Earth today, two of which are about the same size as one of the pyramids at the famous Giza complex in Egypt. The first of these space rocks, known as 2015 HM10, has already made its closest approach when it came within about 2.9 million miles of our planet at 2:00 a.m. EDT this morning. The asteroid—which is estimated to measure up to 360 feet in diameter—whizzed past at speeds of around 21,000 miles per hour relative to the Earth. The second of the asteroids—2019 OD—is estimated to be about the same size as...

    Another day, another Asteroid! It was just yesterday when the news of Asteroid 2006 QV89 not hitting our Earth in september came to light. And now NASA has already detected another massive hazardous asteroid, named 2006 QQ23, that has high chances of hitting our Earth next month. According to CNEOS, 2006 QQ23, is expected to move past Earth on August 10th at 7:23 AM ST at a distance of about 0.04977 au which is a rather shorter distance in astronomical terms. It has also been tagged as “hazardous” meaning it has a pretty good chance of hitting our planet if...

    In general, when an asteroid is found to have even a tiny chance of impacting Earth, further observations and measurements are taken. These "astrometric" data refine our understanding of the asteroid's path, improving our understanding of the risk it poses and often excluding any chance of collision altogether. However, the case of asteroid 2006 QV89 is peculiar. The object was discovered in August 2006 and then observed for only ten days. These observations suggested it had a 1-in-7000 chance of impacting Earth on 9 September 2019. After the tenth day, the asteroid was unobservable and has not been seen since....

    …[S]ientists have discovered enough planets around other stars to offer a clearer picture of the average solar system, and to reveal the ways in which our own solar system is really weird. For instance, most systems have gas giant planets, but those "hot Jupiters" tend to orbit very close to their host stars. That makes our solar system an outlier. All our system’s gas giants orbit in the outer solar system, while the inner region is reserved for rocky planets like our own. But according to a new simulation, our home system is even weirder than we thought. One of...

    A newly found asteroid has been spotted orbiting the Sun, whizzing past the star every 151 days, the shortest orbit of any space rock on record. Known as 2019 LF6, this asteroid is quite large, at 1 kilometer (0.6 miles) across and is part of the "Atira" asteroid group, 20 space rocks whose orbits fall entirely within Earth's. "Thirty years ago, people started organizing methodical asteroid searches, finding larger objects first, but now that most of them have been found, the bigger ones are rare birds," says Quanzhi Ye, a postdoctoral scholar at Caltech who discovered 2019 LF6, in a...

    AN ASTEROID with the destructive power of 2,700 megatons of explosive TNT risks slamming into the Earth later this year, NASA’s asteroid trackers have revealed. The imposing asteroid, dubbed Asteroid FT3, will come barrelling past our home planet on October 3, 2019. NASA expects the flyby to mark the first of 165 approaches between 2019 and 2116. On any one of these asteroid flybys, the risk of cataclysm is low but should the asteroid veer off course and straight into Earth, the results could be cataclysmic. Asteroid FT3 is a monstrous rocky object measuring an estimated 1,115ft (340m) in diameter....
