21068

21068 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on September 24, 1960, by the Indiana Asteroid Program at Goethe Link Observatory in Brooklyn, Indiana. The asteroid is named after the year of its discovery, 21068.

The orbital period of 21068 is approximately 3.61 years, and its semi-major axis is about 2.37 astronomical units (AU). The eccentricity of its orbit is 0.16, and its inclination to the ecliptic is 1.8 degrees. These orbital parameters place 21068 in the inner region of the asteroid belt.

The absolute magnitude of 21068 is 14.5, which corresponds to a diameter of about 3.8 kilometers, assuming an albedo of 0.2. The albedo is a measure of the reflectivity of the asteroid's surface, and a value of 0.2 is typical for asteroids in the inner belt.

21068 is a member of the Flora family, a large group of asteroids that share similar orbital elements. The Flora family is thought to have formed from a single parent body that was disrupted by a collision. The members of the family have a low albedo and a spectral type that is indicative of a stony composition.

In summary, 21068 is a small asteroid in the inner region of the asteroid belt, with an orbital period of approximately 3.61 years. It is a member of the Flora family and has a stony composition. The asteroid was discovered in 1960 and is named after the year of its discovery.
