Orbit and dynamics

The path is an ellipse reaching 0.834 AU from the Sun at perihelion and 1.036 AU at aphelion, a radial span of 0.202 AU.

Applying Kepler's third law to a = 0.935 AU gives an orbital period of 0.90 yr, or about 330 days.

An eccentricity of 0.108 makes the orbit moderately elongated.

Its inclination of 2.48° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 34.3 km/s at perihelion and falls to 27.6 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

Neither a measured diameter nor a reliable absolute magnitude is available for 2015 VU64, so its physical size remains unconstrained.

Observation record and orbit quality

The current orbit solution is based on 34 observations and has a weighted RMS residual of 0.4483 arcseconds.

Condition code U = 5 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.
