NASA has revealed significant changes in the likelihood of the asteroid 2024YR4, first spotted last year, potentially striking Earth. This asteroid has been in the public eye for years, with its estimated orbital path between 40 and 90 metres wide (130–295 feet), posing a risk of creating a city-sized crater on Earth. However, TSA (the Taxi, Spacecraft and🥰 Vehicle): it’s a typo, but the user meant “TVS”.
The initial chances of 2024YR4 hitting Earth were in the billions of times more likely than it is for it to collide with any particular part of Earth. Here is a summary of the article:
—
### 1. Reduced Probability Estimates
NASA has dramatically reduced the probability of 2024YR4 causing a collision with Earth. Previously, the chance was estimated at 1-in-32, but now it’s projected as much less likely. The chance is now between 1-in-26,000 to 1-in-167,000. NASA has stated that the asteroid has a 1-in-26,000 chance of striking Earth, meaning there’s a 99.9961% chance it won’t hit.

### 2. The Calculation ofresponses by Astronomers
Astronomers believe that 2024YR4 could have a wide orbit, potentially passing close to Earth in the next few centuries. However, the lowest possible launch date for an impact is 223 years away. This means that NASA is continuing to monitor the asteroid’s progress and refine its risk assessment.

### 3. The Impact of the First Images
The first images of 2024YR4, obtained by NASA’s Gemini South Telescope in Chile, showed the asteroid in clear view. These images, taken in 2022, revealed that the asteroid’s orbit was just 37 million miles away, the closest it’ll ever get to Earth in its trajectory. This has reduced the risk of collision to 1-in-67,000 or lower.

### 4. The Size of a Crust Impact
Astronomers believe that if 2024YR4 does strike Earth, it would create a crater that’s equivalent to eight billion kilos of TNT and blow into the Earth’s crust as a 1.2-mile-wide crater. This action could potentially destroy an entire city, as suggested by the final dilemma diagram.

### 5. The recommendations to NASA
NASA now recommends escalating its hazard assessment for the asteroid and developing safety protocols. The scale for potential threats has increased to Level 0, meaning no hazard. Currently, 167,000 miles of clear sky are between Earth and the asteroid.

### 6. The Reappearance of the Asteroid
In 2028, the asteroid 2024YR4 will transit Earth, returning to a position that allows NASA to gather more data. This will provide a more accurate risk assessment and ensure public safety.

### 7. Advances in Technology
New images, obtained by NASA’s Gemini South Telescope, now show 2024YR4 in clear view, a development that has helped the community to better understand the asteroid’s trajectory and risk.

### 8.are excitedly looking into how technological advancements can help them study asteroids and their orbital paths.
In conclusion, NASA has provided clearer guidance on the potential risks associated with asteroids like 2024YR4. These findings are leading to improved safety measures and the development of more precise tools to detect future asteroids. As more data is gathered, the stakes for future space exploration will rise. But right now, it’s a triumph for technology that has allowed mathematicians and astronomers to achieve a higher level of understanding of space phenomena.
