2016 NU90

2016 NU90 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 2.512 AU it takes 3.98 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.949 AU from the Sun at perihelion and 4.075 AU at aphelion, a radial span of 3.126 AU.

Applying Kepler's third law to a = 2.512 AU gives an orbital period of 3.98 yr, or about 1,454 days.

The high eccentricity (0.622) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 11.01° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 38.9 km/s at perihelion and falls to 9.1 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 NU90, so its physical size remains unconstrained.

Observation record and orbit quality

The current orbit solution is based on 15 observations and has a weighted RMS residual of 0.92 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.
