 * [[file:Scale of solar system.ods]] 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)
 * 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?

Note- **eccentricity** means: the ratio of the distance of the center of the orbit of a heavenly body from the center of the body round which it revolves to the semi-transverse axis of the orbit.)

 * Assignment**
 * 1) Download and open the Planets Data in Open Office Calc.
 * 2) Open a new Open Office text document.
 * 3) Decide on a category to sort the data. Create a graph with correct labels based on the sorted data.
 * 4) Click on the graph to select it. Copy it and paste it into the text document.
 * 5) Explain the graph. How was the data sorted? What data is included on the graph? Provide a sentence summary of the science information on the graph.
 * 6) Repeat for 2 other graphs.
 * 7) Insert a column in the graph. From the Planetary Fact Sheet above, add a column to the spreadsheet. Sort the data. Create a graph. Copy it and put it on the text document. Provide an explanation of the graph.
