NASA is closely monitoring asteroid 2026 FB as it makes a near-Earth pass, highlighting ongoing efforts to track and study objects that could pose potential risks.
The asteroid, measuring about 69 feet in width, is roughly the size of a small aeroplane. It made its closest approach to Earth on March 18, 2026, travelling at a speed of around 34,000 mph. At its nearest point, it passed at a distance of approximately 683,000 miles (1.1 million kilometres), which is nearly 3 times the distance between Earth and the Moon.
According to NASA, there is no immediate threat from asteroid 2026 FB. Experts noted that even if a similar-sized object were to enter Earth’s atmosphere, it would most likely burn up before reaching the surface. Such an event could produce a bright fireball but would not cause significant damage.
Small near-Earth objects like 2026 FB are relatively common, with thousands passing close to Earth each year. Most are too small to pose serious danger and often go undetected. In contrast, larger asteroids capable of causing regional or global damage are far less frequent.
Scientists rely on ground-based telescopes, radar systems, and international collaboration to track these objects. Monitoring their speed, trajectory, and rotation helps refine predictive models and improve risk assessment.
Studying asteroids like 2026 FB also plays a key role in planetary defence strategies. The data collected helps researchers better understand the behaviour and distribution of near-Earth objects, enabling more accurate identification of potential threats in the future.
