 * Does knowing how to use a scale on a map help you understand how to use scale to measure distances in the universe? Yes. How are they similar?They are similar because a scale map can show you a better understanding of how far things are. How are they different? They are different because the universe is HUGE! and a scale map is alot smaller.
 * 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?it is 99 trillion light years away
 * 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? It is not critical beacause distances in space are too big.
