Orbit and dynamics
Between its closest point (0.964 AU) and its farthest (1.467 AU), the heliocentric distance changes by 0.503 AU over every revolution.
One full revolution takes 1.34 yr (489 days), computed from the semi-major axis of 1.215 AU.
An eccentricity of 0.207 makes the orbit moderately elongated.
The orbital plane is tilted 6.33° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 33.3 km/s at perihelion and falls to 21.9 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
Neither a measured diameter nor a reliable absolute magnitude is available for 2018 TT6, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 9 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3693 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.
