190452364

190452364 is a minor planet located in the outer region of the main asteroid belt between Mars and Jupiter. The object belongs to the background population of main-belt asteroids and does not belong to any known dynamical family.

The asteroid was discovered on 12 December 2013 by the Pan-STARRS survey at Haleakala Observatory in Hawaii. Its provisional designation was 2013 TF105, and it was officially numbered by the Minor Planet Center in 2017. Since its discovery, no name has yet been assigned to the body.

Orbital parameters derived from observations made between 2013 and 2021 indicate that 190452364 has a semi-major axis of 3.04 astronomical units, an orbital period of 5.30 years, and an eccentricity of 0.18. The inclination relative to the ecliptic is 9.3 degrees. These parameters place it in the outer main-belt region, where many dark, carbonaceous objects are found.

Photometric observations suggest that the asteroid has a rotation period of approximately 9.7 hours with a light-curve amplitude of 0.15 magnitudes, indicating a relatively spheroidal shape. Infrared measurements from the WISE mission estimate a diameter between 8.4 and 9.3 kilometers and an albedo of around 0.06, characteristic of C-type (carbonaceous) asteroids.

No spectroscopic observations have been published to date, but the albedo and orbital characteristics make it likely that 190452364 is a carbonaceous C-type asteroid. Current surveys continue to refine its orbit and physical properties, and any future naming proposals will be considered by the International Astronomical Union.
