122177

122177 is a minor planet in the outer region of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 10 October 2000, by astronomers of the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico. The Minor Planet Center designated it as 2000 TQ54, and it was later numbered as 122177.

The object's orbit is characterized by a semi-major axis of about 3.1 astronomical units (AU), an eccentricity of 0.15, and an inclination of 1.8 degrees relative to the ecliptic. Its orbital period is approximately 5.6 Earth years. The asteroid's spectral type is unknown, but it is likely a C-type asteroid, which are common in the outer asteroid belt and are believed to be composed of carbonaceous chondrites.

122177 has not been observed to have any moons or companions. Its rotation period is not known, but it is estimated to be between 2.2 and 24 hours based on its light curve amplitude. The asteroid's absolute magnitude is 14.8, which corresponds to a diameter of about 10 kilometers assuming an albedo of 0.057, typical for C-type asteroids.

The asteroid's name has not been officially assigned by the International Astronomical Union. As of now, it remains a numbered asteroid without a specific name.
