2015 VE66

2015 VE66 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 2.011 AU it takes 2.85 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 1.006 AU from the Sun at perihelion and 3.017 AU at aphelion, a radial span of 2.011 AU.

Applying Kepler's third law to a = 2.011 AU gives an orbital period of 2.85 yr, or about 1,042 days.

The high eccentricity (0.5) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 6.12° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 36.4 km/s at perihelion and falls to 12.1 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 24.1 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.05 km.

Observation record and orbit quality

The current orbit solution is based on 259 observations and has a weighted RMS residual of 0.3528 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.
