2015 EO7

2015 EO7 is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 1.235 AU once every 1.37 yr.

Orbit and dynamics

Between its closest point (1.057 AU) and its farthest (1.413 AU), the heliocentric distance changes by 0.356 AU over every revolution.

One full revolution takes 1.37 yr (501 days), computed from the semi-major axis of 1.235 AU.

An eccentricity of 0.144 makes the orbit moderately elongated.

Its inclination of 4.84° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 31 km/s at perihelion and falls to 23.2 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 = 25.6 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

Astrometry from 36 individual observations underpins this orbit; the fit leaves an RMS residual of 0.538 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.
