26919

26919 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on September 13, 1991, by astronomers Eric Walter Elst and Henri Debehogne at the European Southern Observatory in Chile. The asteroid is part of the Hungaria family, a group of asteroids that share similar orbital characteristics, including a semi-major axis of approximately 1.9 astronomical units (AU) and an orbital period of about 2.1 years.

The Hungaria family is named after the asteroid 434 Hungaria, which was discovered in 1898. These asteroids are believed to have originated from a larger parent body that was disrupted by a collision or other event. The Hungaria family is one of the oldest known asteroid families, with an estimated age of around 200 million years.

26919 has a diameter of approximately 3 kilometers and an absolute magnitude of 15.1. Its orbit is inclined at an angle of about 22 degrees to the ecliptic plane, and it has an eccentricity of 0.12. The asteroid's spectral type is S, indicating that it has a silicate-rich surface composition.

The study of minor planets like 26919 provides valuable insights into the formation and evolution of the solar system. By analyzing the orbits, compositions, and other properties of asteroids, scientists can better understand the processes that shaped our planetary system billions of years ago.
