Pluto, the Sun, and Asterisms In this exercise, we will use Starry Night Enthusiast™ to locate the Sun as seen from Pluto. First, turn off labels for Sun and planets by selecting Options
 Solar System and unclick labels to the right of planets moons. Now select Favourites
 Guides
 Atlas, opening the Options pane and clicking on Constellations
 Boundaries and Constellations
 Labels. Next, open the Find pane and type “Pluto” in the search box. Click the menu button at the extreme left of the listing for Pluto and select Go There. This will place you about 5000 km above the dwarf planet’s surface. Click once on the Up Elevation button to display this altitude in the Viewing Location. You can use the Location Scroller (hold down the Shift key as well as the mouse button while moving the mouse) to move over the surface of a sphere surrounding Pluto at this elevation. Do this until an object that you believe is the Sun lies just to one side of Pluto. (Hint: Think about what Pluto’s phase will be when you are in this position, and move the Location Scroller accordingly.) Place the cursor over that object and use the Heads-up display to see if you are correct. If not, move around with the Location Scroller until you find the Sun. With the Sun next to Pluto, make a simple drawing of Pluto, the Sun, and a few constellations showing the Sun’s location in Pluto’s sky. Is the Sun in the same constellation as seen from Earth? Explain. Next, locate the constellation of Orion. Does it look the same from Pluto as it does from Earth? Explain why or why not.
