Orbit and dynamics
The path is an ellipse reaching 0.928 AU from the Sun at perihelion and 1.624 AU at aphelion, a radial span of 0.696 AU.
Applying Kepler's third law to a = 1.276 AU gives an orbital period of 1.44 yr, or about 526 days.
An eccentricity of 0.272 makes the orbit moderately elongated.
Its inclination of 3.49° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 34.9 km/s at perihelion and falls to 19.9 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 2020 DP14, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 29 observations and has a weighted RMS residual of 0.6231 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.
