A light year is defined as which of the following?

The distance that light travels in one year

The time it takes for light to travel around the Earth

The distance between the Earth and the Sun

The time it takes for the Earth to orbit the Sun

An astronomical unit is defined as which of the following, and how was its distance determined?

The average distance between the Earth and the Sun, determined by observing the positions of planets and using Kepler's laws.

The distance from the Earth to the Moon, determined by radar measurements.

The distance light travels in one year, determined by measuring the speed of light.

The average distance between Mars and the Sun, determined by spacecraft telemetry.

There should be units bigger than light years to measure distances greater than 100 light years. Do you agree?

Yes, because larger units make it easier to express and understand vast distances.

No, because light years are sufficient for all astronomical distances.

Yes, because smaller units are always better for precision.

No, because distances greater than 100 light years are not commonly measured.

If we are 12 light years away from a star, light from which year would we be seeing when looking at it?

We would be seeing light from 12 years ago.

We would be seeing light from the present year.

We would be seeing light from 24 years ago.

We would be seeing light from 6 years ago.

Which of the following scenarios should be using astronomical units?

distance from Mercury to Saturn

Astronomical Unit (AU)

distance from Earth to Sun-used to measure distances within our solar system (ex. distance between Mars and Jupiter)

distance light travels in one year-used to measure distances outside our solar system (ex. measuring distances between stars/galaxies)

Theory of early astronomers. Earth is at the center of the universe. The sun and planets would revolve around the Earth.

Sun is at the center of the solar system.

Which statement is true regarding measuring distances in space?

The Earth is one astronomical unit (AU) from the Sun.

An astronomical unit (AU) is larger than a light year.

The time taken for light to travel through our Solar System is longer than that for light to travel through the Milky Way.

All of the terrestrial planets are more than one astronomical unit (AU) from the Sun.
