Yes, it does help. They are similar because they both help measure pretty large distances. They are different because in the universe the distances are a lot bigger than they would be on a normal map on earth. When the light first left Altair it was 1999, two years before I was born. Altair is 96 trillion miles away. It would be impossible because they might not have the equipment to properly measure such specific distances in space. Its not critical because there might not be such a need for a specific distance, but miles might still be specific enough for distances in space.
 * Click on the link to download the OpenOffice spreadsheet. We will do one problem as a class, then you will work in pairs to complete the other problems. When you are done each of you must create a wiki page called scale value codename, then answer the following questions: (based on lessons from: Astronomical Scales)
 * 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?
 * 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?
 * 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?
 * 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?
