Why do astronomers use astronomical units (AU) instead of kilometers (km)?(1 point) Responses AU is used in astronomy, while km is used in physics. AU is used in astronomy, while km is used in physics. Large distances are easier to express in AU than in km. Large distances are easier to express in AU than in km. AU is used for spacing, while km is used for length. AU is used for spacing, while km is used for length. There are no km in outer space, only AU.

The correct response is: **Large distances are easier to express in AU than in km.**
Astronomical units (AU) are particularly useful in astronomy because they provide a more manageable scale for the vast distances between celestial objects, such as the distance from the Earth to the Sun, which is 1 AU. Using kilometers for these distances would result in very large numbers that can be cumbersome to work with.
