10389

10389 is a number that appears in various contexts across mathematics, astronomy, and popular culture, often due to its unique properties or associations. In mathematics, 10389 is notable as a composite number, meaning it is not a prime and can be factored into smaller integers. Its prime factorization is 7 × 7 × 21 = 7² × 21, which simplifies to 7² × 3 × 7 = 3 × 7³. This number is also a Harshad number, or Niven number, as it is divisible by the sum of its digits (1 + 0 + 3 + 8 + 9 = 21, and 10389 ÷ 21 = 495).

In astronomy, 10389 is the designation of an asteroid discovered on October 16, 1996, by the Spacewatch program at Kitt Peak Observatory in Arizona. This minor planet is part of the main asteroid belt located between Mars and Jupiter. Its provisional designation was initially 1996 UH1, and it has since been cataloged as 10389 in the Minor Planet Center’s database. Little is known about its physical properties, such as size or composition, though it follows a typical orbit within the asteroid belt.

The number 10389 also appears in popular culture, particularly in the 2001 film *A Beautiful Mind*, where it is referenced as a key sequence in the mathematical puzzles solved by the protagonist, John Nash. While not a significant mathematical discovery, its inclusion in the film highlights how numbers and sequences can symbolize complex ideas in storytelling.

Overall, 10389 serves as an example of how a seemingly arbitrary number can hold meaning in different fields, from pure mathematics to celestial observation and creative expression.
