Introduction to starry night lab worksheet Pleiades information 1) What is the distance of the pleiades open cluster from earth in light years? 430 light years 2) What is the diameter of the pleiades open cluster in light years? 15.1 light years 3) Without using any measurement tools look at the image of the Pleiades cluster on your screen, in particular look at the 3 stars Merope, Alcyone and Maia. Based on this two dimensional view of the stars, which star (Alcyone or Maia) appears closer to the star Merope? (answer is complete sentences) Without using any measurement tools I think that Alcyone is closer to the star Merope. Return to the instructions document to set up the program before attempting to answer the following questions. Pleiades Measurements Fill in the table of star distances from the star Merope. Star name Distance from Merope (ly) Taygeta 29.4 Celaeno 4.45 Electra 24.7 Maia 4.26 Asterope 9.17 Alcyone 23.1 Now look at the distances from the table you completed. Which star (Alcyone or Maia) is closer to Merope and by how many light years? (answer in complete sentences) Maia is closer than Alcyone to Merope by 18.84 light years. Explain why the distance measured is so different from how the stars appear in the image. (Think about what the measurement tool is actually measuring compared to what you can see looking at the screen.) (answer in complete sentences) The distance measured is so different because we are only able to measure in the 2nd dimension. If it was looked at in the 3rd dimension with depth than it would have been much easier to measure and look at how far apart the stars really are relative to Merope.
