Orbit and dynamics
Between its closest point (0.807 AU) and its farthest (1.457 AU), the heliocentric distance changes by 0.65 AU over every revolution.
One full revolution takes 1.20 yr (440 days), computed from the semi-major axis of 1.132 AU.
An eccentricity of 0.287 makes the orbit moderately elongated.
Its inclination of 4.3° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 37.6 km/s at perihelion and falls to 20.8 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 HZ2, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 54 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3406 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.
