    Do AU and \[{{\text{A}}^{\text{o}}}\] represent the same unit of length?

    Answer:

                    No, AU and \[{{\text{A}}^{\text{o}}}\] represent two different units of length. 1 AU = 1 astronomical unit = \[\text{1}.\text{496 }\times \text{1}{{0}^{\text{11}}}\text{m}\] 1 \[{{\text{A}}^{\text{o}}}\] = 1 angstrom =\[{{10}^{-10}}m\].
