Orbit and dynamics
Between its closest point (0.826 AU) and its farthest (1.706 AU), the heliocentric distance changes by 0.88 AU over every revolution.
One full revolution takes 1.42 yr (520 days), computed from the semi-major axis of 1.266 AU.
An eccentricity of 0.348 makes the orbit moderately elongated.
The orbital plane is tilted 10.11° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 38 km/s at perihelion and falls to 18.4 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 2026 ES1, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 22 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4064 arcseconds.
Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
