11551

11551 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on September 24, 1993, by astronomers at the Spacewatch program at Kitt Peak National Observatory in Arizona. The asteroid is approximately 2.5 kilometers in diameter and has an orbital period of about 3.7 years. It is classified as a main-belt asteroid, meaning it orbits the Sun in the region between Mars and Jupiter where most asteroids are found.

The designation "11551" refers to its sequential number in the Minor Planet Center's catalog of asteroids. The name "11551" is assigned by the International Astronomical Union (IAU) and is used to identify the asteroid in scientific literature and databases. The asteroid does not have an official name, but it is sometimes referred to by its provisional designation "1993 SQ1".

11551 is part of the Flora family of asteroids, which are thought to have originated from a single parent body that was disrupted by a collision. The Flora family is one of the largest groups of asteroids in the main belt, containing over 1,000 known members. The asteroids in this family share similar orbital elements and spectral characteristics, suggesting a common origin.

The study of 11551 and other asteroids in the Flora family provides valuable insights into the formation and evolution of the solar system. By analyzing the composition and orbital dynamics of these asteroids, scientists can better understand the processes that shaped the early solar system and the mechanisms that drive its ongoing evolution.
