26661

26661 is a minor planet in the outer region of the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on October 10, 1999, by astronomers of the Lincoln Near-Earth Asteroid Research (LINEAR) project at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico. The asteroid is designated as 26661 and has a provisional designation of 1999 TQ271. It is classified as a main-belt asteroid, with a semi-major axis of approximately 3.1 astronomical units (AU), an orbital period of about 5.6 Earth years, and an orbital eccentricity of around 0.15. The asteroid has a diameter estimated to be between 5 and 10 kilometers, based on its absolute magnitude of 14.5. Its rotation period is not yet determined, but it is expected to be in the range of a few hours to a few days. The spectral type of 26661 is not yet determined, but it is likely to be a C-type asteroid, which are common in the outer asteroid belt and are characterized by their dark, carbonaceous surfaces. The asteroid's orbit is stable and does not pose any threat to Earth. It is named after the famous novel "2666" by Roberto Bolaño, but the naming citation is not yet available in the Minor Planet Center's database.
