Astronomical Unit
The Voyager 1 space probe. It is currently appx. 108 AU away from the Sun and near the edge of the solar system in a region called the Heliopause. It is moving away at a rate of about 3 AU/year. For comparison, Earth is at a distance of 1 AU from the Sun and Pluto is at a distance of appx. 10 AU from the Sun.
The orbital period of the space probe can be calculated using Kepler's third law of planetary motion, which states that the square of the orbital period is proportional to the cube of the semi-major axis of the orbit. Given that 0.5 AU represents the perihelion and 5.5 AU represents the aphelion, the semi-major axis would be the average of these two distances (3 AU). Therefore, the orbital period of the space probe would be approximately 5.2 Earth years.
It is the earth that is in orbit one astronomical unit (AU) from the sun. That's where the AU came from. One AU is the mean distance from the sun to the earth. A link can be found below.
Saturn, Its mean distance is 9.53 AU, where one AU (Astronomical Unit) is the earth to sun distance.
The AU stands for African Union, which is a continental organization consisting of 55 member states in Africa. It aims to promote unity and cooperation among African countries to achieve social, economic, and political progress on the continent.
Au is the symbol for gold
to you

"J'arriverai au ..." mean "I will arrive at / to ..." in English.
Au revoir means "goodbye" in French.
Mercury: 0.39 AU Venus: 0.72 AU Earth: 1.00 AU Mars: 1.52 AU Jupiter: 5.20 AU Saturn: 9.58 AU Uranus: 19.22 AU Neptune: 30.05 AU
AU is the chemical symbol for gold on the periodic table.
Sec is the French word for 'dry'. 'Au sec' may mean 'in a dry place', for example.
It's more convenient for scientists. AU is the distance the earth is from the sun.
Le salon is the living-room or lounge in French. "au salon" in "in the living-room".
Au can refer to gold, Australia, or Austria, depending on context.
