Minor Planets 14001–15000: Diameter Data and Cataloging
The study of minor planets—small solar system bodies that orbit the Sun but are too small to be classified as planets—provides critical insights into the early formation of our solar system. Among these, the group numbered 14001 through 15000 represents a significant sample of celestial objects whose physical dimensions have been estimated by leading astronomical organizations.
Data for these objects is primarily sourced from the Minor Planet Center (MPC), the official body of the International Astronomical Union (IAU) responsible for collecting and disseminating data on minor planets, and the Jet Propulsion Laboratory (JPL), which provides high-precision orbital and physical characteristics.

Key Facts
- Range: This dataset covers minor planets numbered from 14001 to 15000.
- Data Sources: Physical measurements are verified through MPC and JPL records.
- Size Variance: Diameters in this group range from as small as 1.4 km to as large as 58 km.
- Common Scale: A significant majority of these bodies fall within the 2 km to 12 km diameter range.
Analysis of Physical Dimensions
The diameter of a minor planet is a fundamental metric used to determine its mass, volume, and potential impact risk. For the objects in the 14001–15000 sequence, the distribution of sizes is highly varied, reflecting the diverse nature of asteroid families and fragmented remnants.
Size Distribution and Extremes
While most objects in this catalog are relatively small, there are notable outliers. The largest object recorded in this specific range reaches a diameter of 58 km, while the smallest is measured at 1.4 km. These extremes highlight the difference between larger, more stable protoplanetary remnants and smaller fragments resulting from cosmic collisions.
Data Consistency
The consistent referencing of both MPC and JPL indicates a cross-verification process. By combining observational data (MPC) with refined orbital and thermal modeling (JPL), astronomers can arrive at more accurate diameter estimates.

Frequently Asked Questions
What is a minor planet?
A minor planet is a celestial body that orbits the Sun but is neither a planet nor a comet. This category primarily includes asteroids and dwarf planets.
What do MPC and JPL stand for in this context?
MPC refers to the Minor Planet Center, the global clearinghouse for asteroid data, and JPL refers to the Jet Propulsion Laboratory, which provides advanced trajectory and physical data.
Why do the diameters vary so significantly?
The variation is due to the history of the solar system; some are original building blocks (planetesimals), while others are fragments created by collisions between larger bodies.
How is the diameter of these objects measured?
Diameters are typically estimated using a combination of optical observations, thermal infrared radiation measurements, and radar imaging to determine the physical size of the object.
What is the largest object in the 14001–15000 range?
The largest object in this specific dataset has a diameter of 58 km, found within the 14201–14300 numbering block.
