2023 VB5

2023 VB5 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.285 AU it takes 1.46 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.998 AU) and its farthest (1.571 AU), the heliocentric distance changes by 0.573 AU over every revolution.

One full revolution takes 1.46 yr (532 days), computed from the semi-major axis of 1.285 AU.

An eccentricity of 0.223 makes the orbit moderately elongated.

The orbital plane is tilted 16.11° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33 km/s at perihelion and falls to 20.9 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 23.35 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.08 km.

Observation record and orbit quality

Astrometry from 27 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3818 arcseconds.

Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.

About these computed values

Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
