Orbit and dynamics
The path is an ellipse reaching 0.619 AU from the Sun at perihelion and 2.313 AU at aphelion, a radial span of 1.694 AU.
Applying Kepler's third law to a = 1.466 AU gives an orbital period of 1.78 yr, or about 648 days.
The high eccentricity (0.578) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 2.25° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 47.6 km/s at perihelion and falls to 12.7 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 2017 FN1, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 18 observations and has a weighted RMS residual of 0.4006 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.
