15147

15147 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on February 24, 1990, by astronomers Eleanor F. Helin and Kenneth J. Lawrence at the Palomar Observatory in California, USA. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 2.7 astronomical units (AU) and an orbital period of about 4.5 Earth years.

The size of 15147 is estimated to be around 5.5 kilometers in diameter, based on its absolute magnitude and assumed albedo. Its rotation period is approximately 6.4 hours. The asteroid's spectral type is classified as S-type, indicating a stony composition.

15147 has not been named as of my knowledge cutoff in 2023. The process of naming minor planets typically involves a proposal to the International Astronomical Union (IAU), which then votes on the name. Once a name is approved, it is permanently assigned to the asteroid.

The study of minor planets like 15147 contributes to our understanding of the formation and evolution of the solar system. By analyzing their orbits, compositions, and other characteristics, scientists can gain insights into the processes that shaped our planetary neighborhood.
