2016 EV28

2016 EV28 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.949 AU it takes 2.72 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.451 AU) and its farthest (3.447 AU), the heliocentric distance changes by 2.996 AU over every revolution.

One full revolution takes 2.72 yr (994 days), computed from the semi-major axis of 1.949 AU.

The high eccentricity (0.768) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

Its inclination of 1.99° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 59 km/s at perihelion and falls to 7.7 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

No direct size measurement is available; from an absolute magnitude of H = 28.46 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

Astrometry from 68 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3254 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.
