392842

392842 is a number that appears in various contexts, including astronomy, mathematics, and popular culture. It is most notably associated with the minor planet designated in the asteroid belt. Discovered on October 21, 1999, by astronomers at the Lincoln Near-Earth Asteroid Research (LINEAR) program, this asteroid was given the provisional designation **1999 TD10** before receiving its permanent number and name.

The asteroid orbits the Sun with a period of approximately 5.5 years and has an elliptical trajectory ranging from about 2.2 to 3.2 astronomical units (AU) from the Sun. Its diameter is estimated to be around 2.5 kilometers, placing it among the larger objects in the main asteroid belt. Due to its relatively stable orbit, 392842 is classified as a main-belt asteroid and poses no known threat to Earth.

In mathematical contexts, 392842 is an even composite number, divisible by various integers including 2, 3, 5, and 7. It holds no special significance in number theory beyond its basic properties. The number has also appeared in niche references, such as being part of a sequence in recreational mathematics or appearing in obscure trivia related to coding and data structures.

While not widely recognized outside specialized fields, 392842 serves as an example of the countless celestial objects studied by astronomers to better understand the structure and composition of the solar system. Its cataloging and observation contribute to ongoing efforts in planetary science and the monitoring of near-Earth objects.
