Puellarus

Puellarus, also known as the "Little Girl," is a minor planet located in the asteroid belt between Mars and Jupiter. It was discovered on September 28, 1916, by astronomer Johann Palisa at the Vienna Observatory in Austria. The asteroid is classified as a main-belt asteroid, which means it orbits the Sun within the asteroid belt.

Puellarus has a relatively small diameter, estimated to be around 10 kilometers. Its orbital period is approximately 4.2 Earth years, and it has an orbital eccentricity of 0.11, indicating a relatively circular orbit. The asteroid's rotation period is not well-determined, but it is believed to be around 12 hours.

The name "Puellarus" is derived from the Latin word "puella," which means "little girl." This name was chosen by the discoverer, Johann Palisa, and it reflects the small size of the asteroid compared to other objects in the asteroid belt.

Puellarus is not a particularly notable asteroid, but it is an interesting example of a main-belt asteroid. Its discovery and naming contribute to the ongoing study and cataloging of objects in the asteroid belt, which provide valuable insights into the formation and evolution of the solar system.
