2016 RQ17

2016 RQ17 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.161 AU it takes 1.25 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.742 AU from the Sun at perihelion and 1.581 AU at aphelion, a radial span of 0.839 AU.

Applying Kepler's third law to a = 1.161 AU gives an orbital period of 1.25 yr, or about 457 days.

An eccentricity of 0.361 makes the orbit moderately elongated.

A steep inclination of 39.88° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 40.3 km/s at perihelion and falls to 18.9 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 = 23.9 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.

Observation record and orbit quality

The current orbit solution is based on 56 observations and has a weighted RMS residual of 0.3848 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.
