100AU

100AU is a distance unit in the astronomy community, often used to express the distance between a celestial object and the Sun. AU stands for astronomical unit, which is the average distance between the Earth and the Sun, approximately 149.6 million kilometers (92.96 million miles). The prefix 100 is appended to denote a multiple of this base unit.

In this context, 100AU represents a distance of approximately 14.96 billion kilometers (9.31 billion miles), equivalent to about 93.4 times the distance between the Earth and the Sun. The term is not an officially recognized unit of measurement by any governing body, such as the International System of Units (SI). However, it is widely used in scientific and academic contexts to simplify the expression of vast distances in space.

Experts use 100AU to describe the positions and orbits of objects in the solar system, especially those within the vicinity of other stars or at the far reaches of the heliosphere. Social and natural sciences often require 100AU for �mileage calculations involving Solar System phenomena, exoplanet detection, and estimates for interstellar distances.

Due to its absence in official metric units, 100AU is considered an informal unit. It provides a tangible notion of astronomical distances, joining a set of other informal units in wide use amongst astronomers, such as light-years (ly) or parsecs (pc). Nonetheless, 100AU's syntax has gained utility among scientists, massively reducing complexities with other far-off scales that have become gigantic.
