2000 RE52

2000 RE52 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.154 AU it takes 1.24 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.868 AU from the Sun at perihelion and 1.44 AU at aphelion, a radial span of 0.572 AU.

Applying Kepler's third law to a = 1.154 AU gives an orbital period of 1.24 yr, or about 453 days.

An eccentricity of 0.248 makes the orbit moderately elongated.

The orbital plane is tilted 18.46° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 35.7 km/s at perihelion and falls to 21.5 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

The measured diameter is 0.15 km, a value from direct size determination rather than from brightness alone.

Its geometric albedo of 0.095 indicates a very dark, carbonaceous-type surface.

Observation record and orbit quality

The current orbit solution is based on 109 observations and has a weighted RMS residual of 0.2857 arcseconds.

Condition code U = 1 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

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.
