Asteroid 2024 YR4 Has a 2.3% Chance: NASA has issued an update regarding asteroid 2024 YR4, a newly discovered near-Earth object that has a 2.3% chance of impacting Earth on December 22, 2032. The discovery, made by astronomers in December 2024, has drawn attention due to its unusual orbit and increasing impact probability. While the chances of a collision remain low, NASA and other space agencies are closely monitoring the asteroid’s trajectory.
This article provides an in-depth look at the asteroid’s characteristics, potential impact risks, and what scientists are doing to assess and mitigate potential threats.

Understanding Asteroid 2024 YR4
1. How Was 2024 YR4 Discovered?
Asteroid 2024 YR4 was first observed on December 27, 2024, by the ATLAS telescope in Chile, which is part of a global network tracking near-Earth objects (NEOs). Initially, its probability of impact was below 1%, but as astronomers collected more data, the estimated risk increased to 2.3% as of February 7, 2025.
2. Size and Speed of the Asteroid
NASA estimates that 2024 YR4 is between 130 to 300 feet (40 to 90 meters) wide—comparable to the Tunguska asteroid, which caused a massive explosion over Siberia in 1908, flattening 800 square miles of forest.
The asteroid is currently traveling at a speed of 15 miles per second (24 km/s), making it a significant object of interest for planetary defense agencies.
What Would Happen If 2024 YR4 Hits Earth?
Although the 2.3% chance of impact is relatively low, NASA has calculated different scenarios based on the asteroid’s possible entry angle and location.
1. Possible Impact Effects
If asteroid 2024 YR4 were to strike Earth, it could result in:
- Localized devastation similar to the Tunguska event (Siberia, 1908).
- A fireball explosion equivalent to multiple nuclear detonations.
- Shockwaves and airbursts capable of damaging buildings and infrastructure.
- Potential tsunami if the asteroid lands in an ocean.
However, 2024 YR4 is not large enough to cause a global catastrophe like the asteroid that led to the dinosaur extinction.
2. Possible Impact Locations
NASA has yet to determine exact impact locations, but simulations suggest that North America, South America, and parts of Europe could experience effects if it enters the atmosphere.
How Is NASA Monitoring 2024 YR4?
NASA’s Center for Near-Earth Object Studies (CNEOS) is leading the effort to track and analyze 2024 YR4’s path. The agency is using ground-based telescopes and radar imaging to refine its trajectory.
Current Monitoring Efforts Include:
- Optical tracking using telescopes from NASA, ESA, and private observatories.
- Radar observations to measure its precise shape, rotation, and surface composition.
- Orbit recalculations to determine if the impact probability increases or decreases over time.

Can We Prevent an Asteroid Impact?
NASA has planetary defense strategies in place to protect Earth from potential asteroid threats. These include:
1. The Double Asteroid Redirection Test (DART) Mission
In 2022, NASA successfully tested DART, a spacecraft designed to deflect an asteroid by impacting it at high speed. The mission proved that kinetic impactors could alter an asteroid’s trajectory.
2. Nuclear Deflection (Last Resort Option)
If an asteroid were too large or too close to impact, agencies could consider nuclear detonation to alter its path. However, this method is controversial due to potential fallout risks.
3. Gravity Tractors & Laser Ablation
Scientists are researching gravity tractors (using spacecraft gravity to pull an asteroid) and laser ablation (vaporizing surface material to change direction) as long-term solutions.
FAQs On Asteroid 2024 YR4 Has a 2.3% Chance
1. Should We Be Worried About Asteroid 2024 YR4?
No. While NASA is closely monitoring it, there is still a 97.7% chance it will miss Earth.
2. When Will We Know for Sure If It Will Hit?
NASA will continue tracking 2024 YR4 until April 2025, when it becomes too faint to observe. New observations in 2028 will refine the impact probability.
3. What Happens If It Gets Closer?
If further calculations show an increased risk, NASA will work with international agencies to prepare deflection or evacuation plans.
4. Has an Asteroid Ever Hit Earth Before?
Yes. The most famous cases include:
- Chicxulub Impact (66 million years ago) – Caused dinosaur extinction.
- Tunguska Event (1908) – Flattened 800 square miles of forest in Siberia.
- Chelyabinsk Meteor (2013) – A 65-foot asteroid exploded over Russia, injuring 1,500 people.
