2020 RE2

2020 RE2 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.423 AU it takes 1.70 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.746 AU) and its farthest (2.1 AU), the heliocentric distance changes by 1.354 AU over every revolution.

One full revolution takes 1.70 yr (620 days), computed from the semi-major axis of 1.423 AU.

The high eccentricity (0.476) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 29.91° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 41.9 km/s at perihelion and falls to 14.9 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 = 25.65 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

Astrometry from 52 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4143 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.
