Apologies for the redundant response in my previous answer. The main problem with this model, if it were to be used to study the dimensions of the solar system, is that the planets are represented in different sizes.
no pick the answer choice
Apologies for the confusion. The correct answer choice is: The planets are represented in different sizes.
Why do astronomers use astronomical units (AU) instead of kilometers (km)?(1 point)
Responses
AU is used for spacing, while km is used for length.
AU is used for spacing, while km is used for length.
Large distances are easier to express in AU than in km.
