Asteroid Threat to the Moon: Odds of 2024 YR4 Collision Go Up
At the beginning of 2025, scientists spotted an unfamiliar space rock traveling through the solar system. They called it asteroid 2024 YR4. At first, it didn’t seem dangerous. But now, new data shows a greater chance it could strike the Moon. This update has sparked interest and some worry about what this impact might mean for moonrise.
Is the Moon in danger? What happens if an asteroid hits it? Could this affect Earth, too?
These are real concerns, and we’re going to explore them. The Moon has been hit by space rocks for billions of years. Its surface is marked with craters that are easy to spot, even from Earth. But when a large asteroid like 2024 YR4 comes this close, we can’t ignore it.
Let’s break down what we know, what could happen, and why this matters not just to scientists, but to all of us.
What is Asteroid 2024 YR4?
2024 YR4 was spotted on December 27, 2024, by an observatory in Chile. It’s roughly 50–67 meters (174-220 ft) wide, comparable to the stone that leveled Siberia in 1908. It spins every 20 minutes and is shaped like a flat disk.
Early this year, it held the highest risk any asteroid had shown, about a 3% chance of hitting Earth. But newer data dashed that threat. Today, Earth is safe, but now the Moon faces a small risk.
The Moon’s Vulnerability
The Moon has no air to protect it. That’s why it’s covered in craters from past hits. If a big asteroid strikes, it could throw dust and rock everywhere. This might cause problems for Moon bases, science tools, or satellites nearby. But don’t worry, its orbit and gravity will stay the same, even after a hit.
Increased Odds: What Changed?
This update became possible because of new observations from the James Webb Space Telescope (JWST), which gave scientists a clearer look at the asteroid’s path. In May, Webb’s infrared camera spotted YR4 again. These fresh measurements improved its predicted path by nearly 20%. As a result, the hit chance went from 3.8% to 4.3%.

NASA’s Center for Near-Earth Object Studies and Johns Hopkins teams made the call. Dr. Andy Rivkin led the work. As NASA says, as new data arrives, “impact probability normally evolves.” Good news: a moon hit still won’t make its orbit shift.
Moonrise: Potential Impact Consequences
If 2024 YR4 hits, it will strike at 17 km/s.That’s fast enough to form fresh craters. Some scientists estimate it could be visible from Earth, maybe even dazzling. Lunar satellites would spot the shockwave and dust.
Future Moon missions could face problems. NASA’s Artemis plans might be delayed. China’s and ESA’s lunar bases could also be affected. A hit could damage equipment or change mission safety. Debris could escape the Moon’s orbit. But Earth risk? Tiny. Any dust reaching here would burn up in our atmosphere.
Moonrise and Public Fascination
We all love the Moon. A possible asteroid crash makes headlines. The chance of seeing a lunar flash drives skywatchers’ interest. It also draws attention on social media.
When space watchers ask, “Could we see it rise like that?” we can talk about real science and risks. It’s a good chance to share how planetary defence works.
Conclusion and Looking Ahead
So, what do we do now on this Moonrise news? We stay alert. NASA plans more JWST and ground telescope tracking, especially in 2028 when YR4 swings back near Earth’s path. For now, there’s no reason to panic.
Even if it strikes, the Moon just gets another crater. But each update sharpens our view and helps keep the Moon and us safe. And maybe, one day, we’ll see an asteroid crash live. That reminds us: space is dynamic, exciting, and sometimes unpredictable.
Frequently Asked Questions (FAQs)
If it hits the Moon, it will make a big crater. Dust and rock will fly up. It won’t hurt Earth, but it may affect Moon missions nearby.
No, YR4 will not hit Earth. New data shows it will pass far away. Scientists say we are safe, and there’s no danger to people or cities.
There is a small chance. The latest report says about a 4% chance by 2032. It may miss, but scientists will keep watching just in case it changes.
Yes, the risk was updated. Recent space data confirms that the Moon remains in the asteroid’s possible path. Earth faces no danger, but scientists are now paying closer attention to the Moon instead.
