2025 EO2

2025 EO2 is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 1.107 AU once every 1.16 yr.

Orbit and dynamics

The path is an ellipse reaching 1.053 AU from the Sun at perihelion and 1.161 AU at aphelion, a radial span of 0.108 AU.

Applying Kepler's third law to a = 1.107 AU gives an orbital period of 1.16 yr, or about 425 days.

With e = 0.049, the orbit is close to circular.

The orbital plane is tilted 14.76° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 29.7 km/s at perihelion and falls to 27 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 = 25.61 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

The current orbit solution is based on 39 observations and has a weighted RMS residual of 0.5451 arcseconds.

Condition code U = 8 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.
