Comparing Distance & Size in Universe

A light-year is a measure of (a)   .

• time
• speed
• distance
• brightness

The distance light can travel in one year is (a)   .

• 15,000 kilometers
• 1 light-year
• 15 Astronomical Units
• 6,000 miles

Light-Years are used to measure great distances in space. Which of the following is NOT an example of when you would use light years as a measurement?

• Distance between two galaxies.

• Distance from the Sun to the next closest star.

• Distance from the Sun to Earth.

• Distance across the Milky Way galaxy.

It takes 8.9 years for light produced on Carinae V602 to reach the sun.  If Star X is 30 times farther away from the Sun than Carinae V602 is, how far is Star X from the Sun to the nearest light year? You may use a calculator to find your answer.

• 5358
• 632

If two stars are 100 light-years apart, what does that mean?

• It would take 100 years for a spaceship to travel between these two stars.

• It takes 100 years for light to travel from one star to the other.

• One of the stars formed 100 years before the other.

• The stars are 100 million kilometers from each other.
