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?
 * Yes, by using a scale on the map helps me understand how to use a scale to measure distance in the universe. They are similar because it helps you picture what the distance may look like. They are different because the scales are different between the universe compare the scale on the map.

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?
 * 16 Years ago my brother was in my mother's womb and I was not born yet. Also, the star's light was coming to the Earth. To find the distance of the Altair, you times 16.6 miles to 6 trillion 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?
 * It is difficult to measure in AU (stellar distances) within a few feet because AU is for measuring long distances such as space. It is important to have accuracy when dealing astronomical distances because if you are an astronaut and you need to know the distance between the earth and where you are in space, you want a accurate answer in AU.
