2017 DK34

2017 DK34 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.217 AU it takes 1.34 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.826 AU from the Sun at perihelion and 1.609 AU at aphelion, a radial span of 0.783 AU.

Applying Kepler's third law to a = 1.217 AU gives an orbital period of 1.34 yr, or about 490 days.

An eccentricity of 0.322 makes the orbit moderately elongated.

Its inclination of 4.34° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 37.7 km/s at perihelion and falls to 19.3 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

No direct size measurement is available; from an absolute magnitude of H = 26.8 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.

Observation record and orbit quality

The current orbit solution is based on 42 observations and has a weighted RMS residual of 0.5028 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.
