429664

429664 is a minor planet designation used for an asteroid orbiting the Sun. It is one of the many thousands of small bodies that populate the Solar System, with the majority located in the main asteroid belt between Mars and Jupiter. As a numbered minor planet, 429664 represents an object whose orbit has been sufficiently well determined to receive a permanent catalog entry.

The number 429664 indicates its sequential order in the formal process managed by the Minor Planet Center, which assigns numbers after observations confirm the object's orbit. Many such objects also have provisional designations from their discovery, and they may later receive a formal name if an appropriate designation is proposed and approved by the International Astronomical Union. If no name has been assigned, the object is typically referred to by its number.

In terms of orbit, 429664 is classified within the broader population of main-belt asteroids. Objects in this region generally orbit the Sun at distances of about 2.1 to 3.3 astronomical units (AU) with orbital periods ranging roughly from three to six years and modest inclinations relative to the ecliptic. The exact orbital elements for 429664 are maintained in the databases of the Minor Planet Center and NASA's Jet Propulsion Laboratory, where updated ephemerides and physical properties, when available, are published.

Physical characteristics such as diameter, albedo, and spectral type, if known, are compiled from dedicated observations and surveys. When data are incomplete, estimates are described as such. The article remains neutral about any naming beyond the numerical designation until an official name is assigned.
