Jun 21, 2024 · Imagine if scientists discovered a giant asteroid with a 72% chance of hitting the Earth in about 14 years — a space rock so big that it could not only take out a city but devastate a whole...
Jun 21, 2024 · Here’s the scenario: The government has confirmed NASA astronomers detected a never-before-seen asteroid speeding in the direction of Earth—and although it will take 14 years to arrive, there...

Jul 3, 2024 · Second Close Approach. Assembled into this animation, observations from NASA’s Goldstone Solar System Radar show the tumbling asteroid 2024 MK shortly after it made closest approach with our planet on June 29. The 150-meter-wide asteroid’s orbit was slightly altered by Earth’s gravity as it passed. Two days later, on June 29, the same ...
May 1, 2014 · Asteroid vs Earth: Directed by Christopher Ray. With Tia Carrere, Jason Brooks, Tim Russ, Darin Cooper. When a shower of massive meteors threatens an extinction level event on Earth, the world's greatest minds devise a dangerous plan that will take the planet off its axis in order to avoid the impact.
- Assessing The Size of The Asteroid 2023 PDC Problem
- So… What's The Damage?
- How Worried Should We be?
One of the first things astronomers will do with their 13-year lead time is to calculate the size of the asteroid better.NASA saysthat this is done by measuring the amount of light reflected by the asteroid back into space, a quality called the albedo. The more light reflected, then, in principle, the larger the asteroid is. The difficulty with thi...
NASA Advanced Supercomputing expert Lorien Wheeler explained that evaluating the potential damage of 2023 PDC involves building an asteroid impact risk assessment model and considering a lot of different factors, such as asteroid size and other properties, from limited observational data. "There are three main types of impact hazards that we model....
It's important to stress that 2023 PDC is a purely hypothetical object and it isn't on course to impact Earth. In fact, currently, there are no large asteroids predicted to hit Earth for the next 100 years. The object with the highest probability of colliding with Earth was the 1,100 feet (340 m) wide asteroid 99942 Apophis, which was predicted to ...

2 days ago · A massive asteroid spanning a width nearly as large as the Empire State Building’s height can make a “close approach” to Earth in 2029. Asteroid Apophis spans an estimated 1,110 ft in width. For perspective, the Empire State Building is 1,250 ft tall. According to Space.com, on April 13, 2029, Apophis could reach 32,000 km of Earth, which ...
Jul 5, 2024 · The same team observed asteroid 2024 MK passing our planet at a distance of only 184,000 miles (295,000 kilometers), slightly more than three-quarters of the distance between the moon and Earth ...
