Orbit and dynamics
Between its closest point (0.628 AU) and its farthest (1.127 AU), the heliocentric distance changes by 0.499 AU over every revolution.
One full revolution takes 0.82 yr (300 days), computed from the semi-major axis of 0.878 AU.
An eccentricity of 0.284 makes the orbit moderately elongated.
Its inclination of 0.34° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 42.6 km/s at perihelion and falls to 23.7 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 DN5, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 21 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4324 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.
