The asteroid's orbit is relatively stable, with an eccentricity of 0.12 and an inclination of 11.5 degrees relative to the ecliptic plane. 20477 has not been observed to have any moons or companions. Its spectral type is S, indicating a stony composition. The asteroid's absolute magnitude is 14.1, which is a measure of its brightness. 20477 is not considered a potentially hazardous object, as its orbit does not bring it close to Earth. The asteroid's name is not yet assigned, as it has not been officially named by the International Astronomical Union.
