Orbit and dynamics
The path is an ellipse reaching 1.015 AU from the Sun at perihelion and 2.887 AU at aphelion, a radial span of 1.872 AU.
Applying Kepler's third law to a = 1.951 AU gives an orbital period of 2.73 yr, or about 995 days.
The high eccentricity (0.48) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 2.78° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 36 km/s at perihelion and falls to 12.6 km/s at aphelion.
Size and surface
Neither a measured diameter nor a reliable absolute magnitude is available for 2019 EF3, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 84 observations and has a weighted RMS residual of 1.535 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.
