20181154

20181154 is a minor planet in the outer region of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 11 November 2018, by astronomers using the Pan-STARRS telescope at Haleakala Observatory in Hawaii. The object has a semi-major axis of about 3.1 astronomical units (AU), with an orbital period of approximately 5.6 Earth years. Its orbit has an eccentricity of 0.15 and an inclination of about 11 degrees relative to the ecliptic plane. The absolute magnitude of 20181154 is 16.2, indicating a relatively small size for a main-belt asteroid. The object's spectral classification is not yet determined, but it is likely to be a common S-type asteroid, similar to many other objects in the asteroid belt. As of now, no moons or other companions have been detected around 20181154. The asteroid's orbit is stable and does not pose any threat to Earth. Further observations and studies are needed to better understand the physical properties and composition of this minor planet.
