Copy of Astronomical Measurements and Solar System Modeling

Multiple Choice

Which of the following is a key reason why standard measurements aren't sufficient for astronomical distances?

• Standard units are too small for cosmic scales

• Astronomers prefer to use ancient units

• Standard units are not accurate enough

• Standard units are only used on Earth

Open Ended

Why do astronomers use special units of measurement instead of standard units like meters or kilometers when studying the universe?

Multiple Choice

Which unit is most appropriate for measuring the distance between the Earth and the Sun?

• Astronomical Unit (AU)

• Light Year

• Kilometer

• Parsec

Multiple Choice

What is the main difference between an astronomical unit (AU) and a light year?

• AU measures distances within the solar system, while a light year measures interstellar distances.

• AU is used for time measurement, while a light year is used for distance.

• AU is a larger unit than a light year.

• AU measures the distance light travels in one year.

Multiple Choice

Why are standard units of measurement not sufficient for astronomical distances?

• Because astronomical distances are extremely large compared to everyday measurements

• Because standard units are not accurate enough

• Because astronomers prefer to use their own units

• Because standard units change over time
