A light year is the 

• distance that light travels in one year
• Speed at which light travels 
• Distance between the sun and the earth. 
• Distance at which light no longer exists. 

What is an astronomical unit (A.U.)?

• the time it takes light to travel one year

• the distance between the Earth and the Moon

How bright a star APPEARS FROM EARTH is called what?

• apparent magnitude
• absolute magnitude
• size
• position in the sky

Why do we use light years and astronomical units to measure distances in space?

• Scientists want to sound smart.

• Hubble discovered these units and wanted to use them.

• Space is too small to use km, it wouldn't make sense.

• Space is too big, vast, enormous to use traditional units, like miles.

Which of the following scenarios would be appropriate to use light years?

• From the sun to Earth

• from Earth to Neptune

• from the Milky Way to its closest galaxy

• Asteroid Belt to the Kuiper Belt

Which of the following scenarios would we use Light Years to determine, not Astronomical Units (AU)?

• distance from Mercury to Saturn

• distance from Sun to Neptune

• distance from Earth to Sun

• distance from Asteroid Belt to the Betelgeuse Star

This geometrically derived unit equals about 3.26 light years

• Astronomical Unit

• Light year

• Parsec

• Light second
