Asteroid 2024 YR4: Could It Hit Earth in 7 Years? Here’s What Astronomers Know
Astronomers are closely tracking a newly discovered asteroid, 2024 YR4, which has a small chance of colliding with Earth in seven years. While the possibility of impact remains low, scientists are taking no chances in studying its trajectory and potential effects.
How Big Is the Asteroid?
NASA estimates that 2024 YR4 measures between 130 feet and 300 feet across. If it were to hit Earth, it would likely strike at an estimated speed of 38,000 mph, according to the Center for Near Earth Object Studies at NASA’s Jet Propulsion Laboratory.
Although an asteroid of this size could cause significant local damage, it would not pose a global threat like the catastrophic space rocks seen in disaster movies. For an asteroid to threaten humanity on a large scale, it would need to be much bigger.
When and How Was It Discovered?
Astronomers first detected 2024 YR4 on December 27, 2028, using the Asteroid Terrestrial-impact Last Alert System (ATLAS) station in Chile. Since then, researchers have been tracking the space rock using ground-based telescopes to refine its orbit and assess any potential risks.
What’s Next for Tracking the Asteroid?
The asteroid will remain visible to ground-based observatories until April 2025. After that, it will become too faint to observe until approximately June 2028, when it reappears in Earth’s vicinity.
In March 2025, NASA’s powerful James Webb Space Telescope (JWST) will take a closer look at 2024 YR4 to gather more precise data on its size, shape, and composition. This information will help scientists refine their predictions about the asteroid’s future path.
Should We Be Concerned?
For now, there is no immediate cause for alarm, as astronomers continue to monitor 2024 YR4 closely. If any adjustments in its trajectory suggest a higher risk of impact, scientists will have time to develop potential strategies for planetary defense.
