Characteristics and Orbital Status of Asteroid 2026 FG6

Asteroid 2026 FG6 is a newly identified Near-Earth Object (NEO) that was first detected on March 25, 2026. Following its discovery, astronomers utilized rapid orbital refinement techniques to track the object, extending its observational data arc to three days.[1] As of March 28, 2026, the JPL Solution 3, which incorporates 29 distinct observations, provides the most current trajectory model for the object. Despite these refinements, the asteroid maintains a condition code of 7, indicating that while the orbit is better understood, it remains in a high-uncertainty classification typical of early-stage tracking for small solar system bodies.[1] [2]

According to www.iAsk.Ai - Ask AI:

The asteroid is confirmed to pass through the Earth–Moon system on March 29, 2026. The trajectory includes a lunar pass followed by a close approach to Earth at a distance of approximately $0.00470\mathrm{\text{au}}$, which is equivalent to roughly 1.83 lunar distances.[1] In the study of celestial mechanics, the distance of a close approach is often calculated using the astronomical unit ($au$), where $1\mathrm{\text{au}}\approx 149,597,870\mathrm{\text{km}}$. The encounter is classified by planetary scientists as non-hazardous, as the object poses no threat of impact during this flyby.[1] [2] The gravitational influence of the Moon serves as a significant perturbation point in the asteroid's path, a phenomenon well-documented in the study of orbital dynamics.[3] [4]
