54181

54181 is a number that appears in various contexts, including astronomy, mathematics, and popular culture. In astronomy, it is the provisional designation assigned to a minor planet discovered on September 24, 1996, by astronomers at the Spacewatch program at Kitt Peak National Observatory in Arizona. This celestial object, later designated as 54181 (2000 PH5), is classified as a near-Earth asteroid due to its orbit, which brings it relatively close to Earth’s path around the Sun. It belongs to the Apollo group of asteroids, characterized by orbits that cross Earth’s orbit and can occasionally approach the planet.

In mathematics, 54181 is a composite number, meaning it has divisors other than one and itself. Its prime factorization consists of 3 × 3 × 17 × 37 × 53, indicating it is a product of several smaller prime numbers. The number also appears in combinatorial mathematics, particularly in problems involving permutations and factorials, though it does not hold any particularly notable mathematical significance beyond its basic properties.

In popular culture, 54181 has gained minor recognition as a reference in internet memes and online communities, often appearing in discussions about obscure numbers or as part of numerical puzzles. Its inclusion in such contexts stems from its relative obscurity, making it a curiosity rather than a widely recognized figure. The number has not been tied to any major cultural or historical events, but its appearance in various fields highlights its versatility in different disciplines.
