2016 RN41

2016 RN41 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.014 AU it takes 1.02 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.693 AU) and its farthest (1.335 AU), the heliocentric distance changes by 0.642 AU over every revolution.

One full revolution takes 1.02 yr (373 days), computed from the semi-major axis of 1.014 AU.

An eccentricity of 0.316 makes the orbit moderately elongated.

The orbital plane is tilted 9.58° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 41.1 km/s at perihelion and falls to 21.3 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

Neither a measured diameter nor a reliable absolute magnitude is available for 2016 RN41, so its physical size remains unconstrained.

Observation record and orbit quality

Astrometry from 10 individual observations underpins this orbit; the fit leaves an RMS residual of 0.392 arcseconds.

Condition code U = 9 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.
