189155

189155 is a minor planet that belongs to the asteroid belt between the orbits of Mars and Jupiter. It was discovered on September 22, 1973, by Czech astronomer Luboš Kohoutek at the Bergedorf Observatory in Lüneburg, Germany.

The orbital characteristics of 189155 indicate that it is a relatively small asteroid with a diameter of approximately 2.5 kilometers. Its orbital eccentricity is low, suggesting that it is a stable asteroid with a nearly circular path around the Sun. The asteroid takes approximately 4.5 years to complete one orbit around the Sun, which is relatively close to the average orbital period of the asteroid belt.

As of the last observational update, 189155's orbital elements are highly uncertain, and its actual shape and size are not precisely known. Further observational data or other multi-spectral measurements are needed to improve our understanding of this minor planet.

Asteroids like 189155 provide valuable insights into the early formation and evolution of the solar system. By studying their composition and orbital behavior, scientists can gain a better understanding of the planet formation process and the history of our cosmic neighborhood. The classification of 189155 as a member of the asteroid belt is but one aspect of a much larger and more complex picture, which is still being studied and refined by astronomers and planetary scientists today.
