NASA Tracks Asteroid 2025 BS4 as It Zooms Past Earth at 35,000 MPH
This week, the skies are buzzing with activity as NASA closely monitors asteroid 2025 BS4, a near-Earth object (NEO) set to pass by our planet at a staggering speed of 35,000 miles per hour—ten times faster than a speeding bullet. While the asteroid will remain at a safe distance of 511,000 miles, its proximity has sparked conversations about planetary defense and the potential risks posed by such celestial bodies.
What Makes 2025 BS4 Significant?
Table of Contents
Asteroid 2025 BS4, classified as a near-Earth object (NEO), is one of over 37,000 asteroids discovered by NASA that orbit the sun and occasionally come close to earth. According to NASA’s Jet Propulsion Laboratory, NEOs are defined as asteroids or comets that can approach within 30 million miles of Earth’s orbit. While 2025 BS4’s distance is twice that of the moon, its classification as an NEO underscores the importance of continuous monitoring.
The asteroid measures approximately 23 feet in width—slightly smaller than an average American school bus—and weighs as much as a blue whale, tipping the scales at over 970,000 pounds. If it were to collide with Earth,the impact would release energy equivalent to 19,000 tons of TNT,enough to cause catastrophic damage to a large city.
The Role of NASA’s Planetary Defense efforts
NASA’s Centre for Near-earth Object Studies (CNEOS) is at the forefront of tracking and analyzing asteroids like 2025 BS4. Using the Sentry asteroid monitoring system, scientists constantly evaluate the trajectories of these objects to predict potential impacts over the next century.
Frank Marquise, a renowned astronomer at the SETI Institute and founder of the Citizen Astrologists Network, emphasized the importance of global vigilance. “Asteroids can approach Earth at any moment,” he told the Daily Mail. “Watching the sky everywhere in the world allows us to follow them.”
While 2025 BS4 is not classified as a possibly hazardous asteroid (PHA)—a designation reserved for objects at least 460 feet in diameter that can come within 4.65 million miles of Earth—its passage serves as a reminder of the need for preparedness.
lessons from NASA’s DART Mission
In 2022, NASA’s double Asteroid Redirection Test (DART) mission demonstrated humanity’s ability to alter an asteroid’s trajectory. The spacecraft intentionally collided with Dimorphos, a 560-foot asteroid orbiting a larger companion, Didymos, at a speed of over 14,000 miles per hour. The impact successfully changed Dimorphos’ orbit,proving that the kinetic impactor technique coudl be a viable planetary defense strategy.
“The good news is that we had an experience that showed we are able to divert an asteroid’s path if we knew in advance that such a collision would happen,” Marquise said.”This changes a lot of our way of thinking about this problem.”
The European Space Agency’s upcoming mission to Dimorphos in 2026 will provide further insights into the effectiveness of this technique.
A Week of Celestial Flybys
While 2025 BS4 is the star of the show, it’s not the only asteroid making a close approach this week. On January 28, another bus-sized asteroid, 2025 BF5, will pass by at a distance of 797,000 miles.Later in the week, two more asteroids—one the size of a bus and another the size of a house—will approach Earth at distances of 1.63 million miles and 2.33 million miles, respectively.
Key Takeaways
| Asteroid | Size | Distance from Earth | Speed |
|—————–|——————-|————————–|——————–|
| 2025 BS4 | 23 feet | 511,000 miles | 35,000 mph |
| 2025 BF5 | Bus-sized | 797,000 miles | Not specified |
| unnamed | Bus-sized | 1.63 million miles | Not specified |
| Unnamed | House-sized | 2.33 million miles | Not specified |
Looking Ahead
As NASA continues to refine its planetary defense strategies, the agency remains committed to safeguarding Earth from potential asteroid threats. While none of the currently tracked PHAs pose an imminent risk, the lessons learned from missions like DART and the ongoing monitoring of NEOs ensure that humanity is better prepared for any future challenges.
For now, asteroid 2025 BS4 and its companions will pass by harmlessly, offering a glimpse into the dynamic and ever-changing nature of our solar system.

understanding the Significance of Asteroid 2025 BS4
Senior Editor: Dr. Carter,what makes asteroid 2025 BS4 stand out among the thousands of near-Earth objects NASA tracks?
Dr. Eleanor Carter: Asteroid 2025 BS4 is particularly noteworthy because of it’s speed and proximity.While it’s not the largest asteroid we’ve observed, traveling at 35,000 miles per hour—ten times faster then a speeding bullet—makes it a captivating subject for study. Additionally, its close approach of 511,000 miles is a reminder of how dynamic our solar system is. Although this distance is more than twice that of the moon, it’s still classified as a near-Earth object, which means it warrants careful monitoring.
NASA’s Planetary Defense efforts
Senior Editor: How does NASA track and assess the potential risks posed by asteroids like 2025 BS4?
Dr. Eleanor Carter: NASA’s Center for Near-Earth Object Studies (CNEOS) plays a critical role in tracking these celestial bodies. They use the Sentry asteroid monitoring system, which continuously evaluates the trajectories of asteroids to predict any potential impacts over the next century.
