2025 PC3

2025 PC3 is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 1.419 AU once every 1.69 yr.

Orbit and dynamics

Between its closest point (1.146 AU) and its farthest (1.692 AU), the heliocentric distance changes by 0.546 AU over every revolution.

One full revolution takes 1.69 yr (617 days), computed from the semi-major axis of 1.419 AU.

An eccentricity of 0.192 makes the orbit moderately elongated.

The orbital plane is tilted 11.43° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 30.4 km/s at perihelion and falls to 20.6 km/s at aphelion.

Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 23.48 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.07 km.

Observation record and orbit quality

Astrometry from 23 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3298 arcseconds.

Condition code U = 6 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
