 * 1) Does knowing how to use a scale on a map help you understand how to use scale to measure distances in the universe? How are they similar? How are they different?
 * 2) Vast distances in space are often measured in light-years. A light-year is the distance that light travels in one year, or about 6 trillion miles. Altair, a star in the constellation Aquila, is 16.6 light-years away, which means that the light we see now from that star left its surface 16 years and 219 days ago. Describe what was happening in the world when the light we are seeing from Altair first left that star. How far away is Altair in miles?
 * 3) Explain why it would be impossible for scientists to measure stellar distances that are accurate to within a few feet. Why is it not critical to attain such accuracy when dealing with astronomical distances?

1. Yes it does, because you have a clear understanding on how to use the scale to measure the distance in the universe. They are similar in a way that you use them both to measure the distances from one object to another. They are different by the distance. Here on Earth you can measure the distance from one place to another by using miles, but in the Unirverse, to get to the farthest planet you would have to measure the distance in light years.
 * Answers of Questions:**

2.16 years ago I wasn't born yet, but my parents were together but not married.Altar is 99.6 trillion miles.

3. It would be impossible for scientist to measure stellar distances because they are a big distance far away from eachother. It is not critical to attain accuracy because the distances are too far away to get an accurate measurment.
