Unformatted text preview: Student B : The stars in a constellation are in the same direction in the sky as seen from Earth. m=2 m=3 m=4 m=5 Legend m=1 m=6 Cubis Cylindris Part II : The diagram below crudely illustrates an observer and the stars of Cubis in space. 1) From the observer’s perspective what is the altitude (angle above the horizon plane) of α cubis? 2) From the observer’s perspective what is the altitude of β cubis? 3) Roughly estimate the angular separation in the sky between α cubis and β cubis by determining the difference in their altitudes. 4) How far away is α cubis? How far away is β cubis? Roughly estimate how far apart the two stars are. 5) Can you now do a better job of answering what the relationship is between the stars in a constellation? Restate the relationship. Earth Horizon Plane 10 pc 20 pc 15 pc 25 pc 5 pc 30 pc...
