2010 DL

2010 DL belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.353 AU it takes 1.57 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.928 AU) and its farthest (1.778 AU), the heliocentric distance changes by 0.85 AU over every revolution.

One full revolution takes 1.57 yr (575 days), computed from the semi-major axis of 1.353 AU.

An eccentricity of 0.314 makes the orbit moderately elongated.

Its inclination of 2.57° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 35.4 km/s at perihelion and falls to 18.5 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

The measured diameter is 0.02 km, a value from direct size determination rather than from brightness alone.

Its geometric albedo of 0.08 indicates a very dark, carbonaceous-type surface.

Observation record and orbit quality

Astrometry from 14 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5279 arcseconds.

Condition code U = 8 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.
