Overview of Asteroid 192559 (1998 VO)

Asteroid 192559 (1998 VO) is a well-documented Apollo-class near-Earth object (NEO) that has been classified as a Potentially Hazardous Asteroid (PHA) due to its orbital proximity to Earth and its significant physical dimensions.[1] Apollo asteroids are defined by orbits that cross the path of the Earth, characterized by a semi-major axis $a>1.0$ AU and a perihelion distance $q<1.017$ AU.[2] Scientific analysis, based on over two decades of observational data, confirms that 192559 (1998 VO) has an extremely well-constrained orbit, with a condition code of 0, indicating high precision in its trajectory modeling.[1]

Physical and Orbital Characteristics

The asteroid is estimated to have a diameter ranging between 300 and 700 meters.[1] Its orbital eccentricity is recorded at approximately 0.227, and it possesses an absolute magnitude of 20.4.[3] Like most asteroids, 192559 (1998 VO) is considered a remnant of the primordial solar nebula, representing planetesimal fragments that failed to coalesce into a larger planetary body during the early formation of the solar system.[3] [4] On April 14, 2026, the asteroid is scheduled for a routine flyby at a distance of approximately 0.32726 AU (roughly 48.9 million kilometers or 127.3 lunar distances), traveling at a relative velocity of 17.60 km/s.[1] Despite its PHA classification, current data indicates no impact threat to Earth, as the classification is based on geometric potential rather than immediate collision risk.[1]
