15103

15103 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on September 1, 1997, by the Lincoln Near-Earth Asteroid Research (LINEAR) project, a collaborative effort between the Massachusetts Institute of Technology Lincoln Laboratory, the United States Air Force, and NASA. The asteroid is named after the year of its discovery, 15103.

The asteroid has an estimated diameter of approximately 2.5 kilometers. It orbits the Sun with a semi-major axis of about 2.7 astronomical units (AU), completing one orbit every 4.4 Earth years. Its orbit has an eccentricity of 0.15 and an inclination of 14.5 degrees relative to the ecliptic plane.

15103 is classified as a main-belt asteroid, a group of asteroids that orbit the Sun primarily between Mars and Jupiter. It is part of the Flora family, a large group of asteroids that share similar orbital elements and spectral properties, suggesting a common origin.

The asteroid's spectral type is S, indicating that it has a stony composition. This is typical for main-belt asteroids, which are primarily composed of silicate minerals. The surface of 15103 is relatively bright, with an albedo of about 0.25, which means it reflects about 25% of the sunlight that hits it.

15103 does not pose any significant threat to Earth, as its orbit does not bring it close to our planet. However, its study provides valuable insights into the composition and dynamics of the asteroid belt, contributing to our understanding of the solar system's formation and evolution.
