154998

154998 is a minor planet in the outer region of the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on 14 October 1999, by astronomers at the Lowell Observatory Near-Earth-Object Search (LONEOS) in Flagstaff, Arizona. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 3.1 astronomical units (AU), and an orbital period of about 5.5 Earth years.

The size of 154998 is estimated to be around 10 kilometers in diameter, based on its absolute magnitude and assumed albedo. Its rotation period is approximately 5.6 hours. The asteroid's spectral type is classified as X, indicating a primitive composition, possibly carbonaceous. This suggests that 154998 may contain organic compounds and water, making it of interest to scientists studying the early solar system and the origins of life on Earth.

154998 has not been named as of my knowledge cutoff in 2023. Naming an asteroid typically involves a proposal process by the discoverer or a collaborating astronomer, followed by approval from the International Astronomical Union's Working Group for Small Bodies Nomenclature. The naming process often involves themes related to mythology, literature, or other cultural references.
