2006 MY13

2006 MY13 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.263 AU it takes 1.42 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.493 AU from the Sun at perihelion and 2.033 AU at aphelion, a radial span of 1.54 AU.

Applying Kepler's third law to a = 1.263 AU gives an orbital period of 1.42 yr, or about 518 days.

The high eccentricity (0.61) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 45.05° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 53.8 km/s at perihelion and falls to 13.1 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

No direct size measurement is available; from an absolute magnitude of H = 20.29 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.31 km.

Observation record and orbit quality

The current orbit solution is based on 51 observations and has a weighted RMS residual of 0.743 arcseconds.

Condition code U = 0 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.
