What is the exact, fixed value of the Astronomical Unit ($ ext{AU}$) established by the IAU in 2012?
Answer
Exactly $149,597,870.7$ kilometers
The International Astronomical Union fixed the value of the AU in 2012 to exactly $149,597,870.7$ kilometers, which is equivalent to $1.495978707 imes 10^{11}$ meters, anchoring it to the SI system rather than observational measurement.
