120145

120145 is a number that appears in various contexts across mathematics, astronomy, and popular culture, often due to its unique properties and associations. In mathematics, it is notable for being a **Harshad number** (also known as a Niven number) in base 10, as it is divisible by the sum of its digits (1 + 2 + 0 + 1 + 4 + 5 = 13, and 120145 ÷ 13 = 9242). It is also a **practical number**, meaning all smaller positive integers can be represented as sums of distinct divisors of 120145.

In astronomy, 120145 is the provisional designation of a main-belt asteroid discovered on October 15, 1996, by astronomers at the Spacewatch program at Kitt Peak Observatory. It has since been cataloged as **120145 Bennu**, named after the ancient Egyptian deity Bennu. This asteroid gained significant attention in 2016 when NASA’s OSIRIS-REx mission was launched to study it, collect a sample, and return it to Earth. The mission provided valuable insights into the early solar system and the composition of near-Earth objects.

In popular culture, 120145 is sometimes referenced in puzzles, trivia, and internet memes due to its obscure yet mathematically interesting nature. Its appearance in both scientific and cultural contexts has contributed to its recognition among enthusiasts of numbers, space exploration, and problem-solving. While not widely known outside these fields, its significance in specific areas makes it a point of interest for those studying number theory or planetary science.
