NASA is tracking a near-Earth asteroid called 2026 BJ8 that is moving through space at around 50,000 kmph and is roughly the size of an airplane. Although its speed and relatively close approach to Earth may sound worrying, such asteroids are common and are regularly monitored by space agencies. Scientists have confirmed that 2026 BJ8 does not pose any danger to Earth, and its flyby is mainly valuable for improving knowledge about asteroids that pass near our planet’s orbit.
What Is Asteroid 2026 BJ8 and Why NASA Is Tracking It
Asteroid 2026 BJ8 is a near-Earth asteroid, meaning it orbits the Sun and sometimes passes close to Earth’s orbital path. These rocky objects are leftovers from the formation of the solar system about 4.6 billion years ago and never became part of a planet.
The asteroid has a solid, rocky structure and no atmosphere. Scientists believe it has an irregular shape, which is common for smaller asteroids. Its path through space is predictable and shaped by the gravitational pull of the Sun and nearby planets.

NASA tracks near-Earth asteroids like 2026 BJ8 to accurately calculate their orbits and assess how close they come to Earth. Although it is moving at a high speed, this is normal in space. Scientists emphasize that distance and size, not speed, determine whether an asteroid poses any danger.
Size, Speed, and Structure Explained in Simple Terms
The asteroid 2026 BJ8 measures about 35.5 meters in length, which is roughly the size of a large airplane. In astronomical terms, this places it in the small-to-medium asteroid category. Its size estimates are based on how bright it appears when observed from Earth and how much sunlight it reflects, a method commonly used in asteroid science.
Unlike planets, asteroids do not have smooth surfaces. The surface of 2026 BJ8 is believed to be rocky and uneven, with a rough exterior made of solid stone and minerals. Its irregular shape means it may tumble or rotate as it moves through space, rather than spinning evenly like a ball.
NASA’s 5th Biennial Exercise to tackle Asteroid threats
The asteroid is traveling at around 50,000 kilometers per hour, which may sound extremely fast, but this is typical for objects orbiting the Sun. Space is vast, and high speeds are required for asteroids to maintain their paths around the Sun without falling inward or drifting away.
Despite its size and speed, 2026 BJ8 is much smaller than asteroids known to cause widespread damage. Scientists generally consider asteroids larger than 140 meters to be potentially dangerous if they come very close to Earth. At just over 35 meters, 2026 BJ8 is far below that threshold.
Should You Worry About Its Close Approach to Earth
According to NASA’s calculations, asteroid 2026 BJ8 will pass Earth at a distance of about 3,813,896 kilometers. While this sounds close by everyday standards, it is considered a safe distance in space science. The asteroid will not enter Earth’s atmosphere and will have no physical effect on the planet.
NASA classifies asteroids as potentially hazardous only if they are large in size and pass very close to Earth, within 7.4 million kilometers. Although 2026 BJ8 will come within this range, its size—about 35.5 meters, similar to an airplane—means it does not meet the criteria to be considered dangerous. Both size and distance are critical factors, and in this case, the asteroid is too small to pose a risk.

Scientists have confirmed that there is no chance of collision, no expected atmospheric impact, and no threat to people, satellites, or infrastructure. The flyby is considered a routine event and offers an opportunity to collect useful scientific data.
NASA will continue monitoring 2026 BJ8 to refine its orbital path and improve future predictions. Studying such asteroids helps scientists better understand near-Earth space and track objects that move close to our planet as part of regular space observation efforts.
