NASA‘s Scout system accurately predicted the impact of asteroid 2024 BX1 on Germany, marking an advance in planetary defense by detecting and tracking small, harmless asteroids before they enter Earth’s atmosphere.
Scout’s impact assessment system calculated when and where asteroid 2024 BX1 would impact Earth’s atmosphere, providing a useful demonstration of planetary defense capabilities.
A small asteroid, approximately 3 feet (1 meter) in size, disintegrated harmlessly over Germany at 1:32 a.m. local time (CET) on Sunday, January 21st. 95 minutes before hitting the Earth’s atmosphere. NASA scout The Collision Hazard Assessment System, which monitors data on potential asteroid discoveries, provided advance warning of when and where an asteroid might strike. This is the eighth time in history that a small asteroid has been detected while in space, before entering the atmosphere and collapsing.
The asteroid impact produced a bright fireball (see video below), or bolide. It was observed as far away as the Czech Republic, and small meteorites may have been scattered on the ground at the impact site, about 37 miles (60 kilometers) west of Berlin. . This asteroid was later designated 2024 BX1.

Although NASA reports on near-Earth objects (NEOs) of all sizes, NASA has been required by Congress to detect NEOs larger than 140 meters that could cause significant damage to the surface if they collide with Earth. I have been given the task of tracking. These objects can be discovered much earlier than smaller objects like 2024 BX1.
Small asteroids like this sometimes impact our Earth. They pose no danger to life on Earth, but could provide a useful demonstration for NASA. planetary defense Features like Scout’s quick-response trajectory calculations and impact alerts.
how it was predicted
Asteroid 2024 BX1 was first observed less than three hours before impact by Krystian Sarnetsky at the Piszkestecs mountain station of the Konkoli Observatory near Budapest, Hungary.These early observations reported to minor planet center – Internationally recognized clearinghouse for the positioning of small solar system objects – automatically posted on the Center’s site. Near-Earth Object Confirmation Page so that other astronomers can make additional observations.
Scout is developed and operated by the Center for Near Earth Object Research (CNEOS) NASA’s Jet Propulsion Laboratory in Southern California automatically retrieved new data from that page to estimate the object’s likely trajectory and likelihood of impacting Earth. CNEOS calculates the orbits of all known NEOs and uses the Planetary Defense Coordination Office (PDCO) at NASA Headquarters in Washington.
Late at night on January 20, 2024, astronomer Krystian Sarnetsky detected an asteroid on a course for imminent collision with Earth. Just a few hours later, on Sunday, January 21, at 01:32 CET, it crashed into the planet’s atmosphere 50km west of Berlin, creating this amazing fireball. The asteroid, later named 2024 BX1, was only the eighth asteroid discovered by humans before the collision. Thanks to the quick response and information sharing from Earth’s asteroid and fireball communities, including ESA’s Near Earth Object Coordination Center, the astronomical event occurred with just hours’ notice and in the midst of global warming. Many people were able to see and record this spectacular sight. night. This video was captured by his AllSky7 network.Credit: ALLSKY7 / Sirko Molau – AMS16 Ketzer
With three observations posted on the confirmation page in a 27-minute period, the Scouts initially realized there was a potential impact and that additional observations were urgently needed. As astronomers from all over Europe reported new data to the Asteroid Center, the asteroid’s orbit became better known and the probability of it hitting Earth increased significantly.
Seventy minutes after 2024 BX1 was first discovered, scouts reported a 100% probability of Earth collision and began narrowing down the location and time. As tracking continued and more data became available over the next hour, Scout improved his estimates of time and location. As the asteroid disintegrated in a relatively populated area of the world, many photos and videos of the fireball were posted online minutes later.

Tracking NEO
The first asteroid to be discovered and tracked long before it hit our planet was 2008 TC3The asteroid entered the atmosphere and broke up over Sudan in October 2008. The 4-meter (13-foot) wide asteroid littered the Nubian Desert with hundreds of small meteorites.
In early 2023, another small asteroid will be designated. 2023 CX1was detected over northwest France seven hours before it entered the atmosphere. Similar to the 2024 BX1, the Scout accurately predicted the location and time of impact.
As NEO surveys become more sophisticated and sensitive, these innocuous objects are increasingly detected before they enter the atmosphere, providing a real-world exercise for NASA’s planetary defense program. Details collected from such events help inform government agencies. mitigation strategy If a large and dangerous object is detected that is on a collision course with Earth in the future.
