There isn't one single "2027 asteroid"; rather, this year is significant for potential asteroid flybys or hypothetical impact scenarios, like the 2017 exercise involving Asteroid 2017 PDC, which was estimated to be 200-280 meters (650-900 feet) wide, but this was a simulated threat. Another real asteroid, (137108) 1999 AN10, has a close approach in August 2027, and is significantly larger, potentially 556-1793 meters (over half a kilometer) in diameter, though it's expected to pass safely.
Based on new tracking measurements taken this week, the International Asteroid Warning Network (IAWN) has confirmed that asteroid 2017 PDC is on a course that will almost certainly impact Earth on July 21, 2027, less than nine years from now.
On August 2, 2027, the Earth will witness one of the longest total solar eclipses of the century—lasting over 6 full minutes of darkness! 📍Visible from Europe, North Africa, and the Middle East, this rare celestial event won't be seen again until 2114!
a potentially hazardous asteroid named Apophis. and concluded that there was a 27 percent chance. that it would hit Earth on April 13, 2029. the asteroid was big enough to destroy an entire city, so the public was rightfully terrified. as we observed it more and more, it became clear that our calculations were wrong.
Its full name is Apophis 99942. After Apophis was discovered in 2004, the asteroid was given a 2.7% chance of hitting Earth in 2029, causing a great deal of media attention. It also for a time had a small chance of hitting Earth in 2036. Additional observations have shown it will not hit Earth in 2029 or in 2036.
A 300m-wide asteroid will not hit the Earth in 2036, US astronomers say. It was thought there was a one-in-200,000 chance that it could strike on 13 April 2036, but revised calculations have now ruled this out. Instead, Nasa scientists said it would not get closer than 31,000km as it flies past on this date.
Impacts of projectiles as large as one km in diameter are generally thought to explode before reaching the sea floor, but it is unknown what would happen if a much larger impactor struck the deep ocean. The lack of a crater, however, does not mean that an ocean impact would not have dangerous implications for humanity.
Astronomers closely tracked the asteroid, and now NASA is confident that there is no risk of Apophis impacting our planet for at least 100 years.
The date of the most likely potential impact is July 21, 2027 - over ten years away - but the probability of impact is very low, about 1 chance in 40,000. When first detected, the asteroid is about 0.36 au (54 million kilometers or 33 million miles) from Earth, approaching our planet and getting brighter.
Mid-2027 – Artemis III, the second crewed mission of the Artemis Program and first lunar landing on the Moon since 1972, is scheduled to launch no earlier than this time. June 2027 – The Titanic II is scheduled to make its maiden voyage from Southampton to New York City.
Earth will last for billions of years, but life as we know it will likely end in about 1 billion years as the Sun gets hotter and boils the oceans, making the planet too hot and oxygen-poor; the planet itself will remain until the Sun expands into a red giant in roughly 5 billion years, eventually engulfing it. While minor geological events or asteroid impacts pose shorter-term risks, the Sun's increasing luminosity is the ultimate deadline for Earth's habitability and physical existence.

Yes, this can happen to humanity on Earth… it has happened before! The very source of life for humanity is, indeed, our greatest threat.
Asteroid 2024 YR4 is a near-Earth asteroid. When asteroid 2024 YR4 was discovered, it was estimated to have a very small chance of impacting Earth impact on Dec. 22, 2032. After more observations, NASA concluded it poses no significant impact risk to Earth in 2032 and beyond.
In 2027, NASA is expected to launch the Artemis III mission, which will land astronauts near the south pole of the Moon.
That's not even close to the size of the "planet-killer" asteroid that slammed into Earth 66 million years ago and led to the extinction of dinosaurs. That one was estimated to be about 6.2 miles (10 kilometers) in diameter and marked the last known large asteroid to hit our world.
Even if it did hit us, Apophis would cause localised destruction at best (akin to a large volcano going off), and since most of Earth is ocean, and we can see it coming a mile off and evacuate the area it's going to hit, the odds of it killing anybody at all are vanishingly low.
If the object happened to be on an orbit that had it collide with Earth then there could be less than a year's warning. That is very unlikely. It is slightly more likely that an object will be discovered to be on a collision course only after several orbits, in which case there would be years or decades warning.
Human activity has driven Earth's natural systems dangerously close to collapse. A new study reveals that 60% of the planet's land is now outside the safe operating zone required to maintain stable ecosystems. This alarming shift reflects accelerating environmental pressures.
The asteroids capable of causing a global disaster if they hit the Earth are extremely rare. They probably would need to be about a kilometer or more in diameter. Such bodies impact the Earth only once every 100,000 years on average.
On April 13, 2029, the large asteroid Apophis (99942) will have a very close, but safe flyby of Earth, passing within 32,000 kilometers (20,000 miles) of our planet—closer than some satellites—and will be visible to the naked eye in the night sky from parts of the Eastern Hemisphere (Europe, Africa, Asia) as a bright, fast-moving point of light. This rare event offers scientists a unique opportunity to study an asteroid of its size (about 375 meters wide) up close, with missions like NASA's OSIRIS-APEX and ESA's Ramses planned to observe it.
The asteroid is thought to have been between 10 and 15 kilometres wide, but the velocity of its collision caused the creation of a much larger crater, 150 kilometres in diameter.
An asteroid that may be as wide as the Golden Gate Bridge in San Francisco is tall will fly safely by Earth on Thursday, June 5, 2025. Bigger than 97% of asteroids, for such a large object to come close to Earth is a relatively rare event, but asteroid 424482 (2008 DG5) won't pose any threat.
Given enough warning, yes we could deflect it. As far as how much warning we would get is variable depending on if the asteroid approaches from the sunward side of earth's orbit or from the night side. But an asteroid that size would likely get detected years in advance.
Is the World Going to End in 2029? No, but why do you ask? Asteroid 2004 (MN 4) a.k.a. Apophis Apophis is a near-earth asteroid discovered in 2004. Preliminary orbital calculations indicated that in would slam into Earth on April 13, 2029.
