1RQ 2RQ 3RQ What is the difference between the Moon and a moon?5RQ Why are light-years more convenient than miles, kilometers, or AU for measuring the distances to stars and galaxies?7RQ 8RQ 9RQ 10RQ What are the largest known structures in the Universe?12RQ 13RQ 14RQ 15RQ 16RQ 1P The equatorial diameter of the Moon is 3476 kilometers. If a kilometer equals 0.6214 miles, what is the Moons diameter in miles?3P A typical galaxy is shown on the first page of the Universe Bowl on the inside cover of the printed book. Express the number of stars in this typical galaxy in scientific notation.5P 6P 7P 8P If the speed of light is 3.0 105 km/s, how many kilometers are in a light-year? How many meters? (Hint: First look up or calculate how many seconds are in a year.)10P How long does it take light to cross the diameter of the Milky Way Galaxy?12P 13P 1SP 2SP 3SP 4SP 1LL 2LL 3LL 4LL 5LL 6LL 1RQ 2RQ 3RQ 4RQ 5RQ 6RQ 7RQ 8RQ 9RQ 10RQ 11RQ 12RQ 13RQ 14RQ 15RQ 16RQ 17RQ 18RQ 19RQ 20RQ 21RQ 22RQ 23RQ 24RQ 25RQ 26RQ 27RQ 28RQ 1P 2P 3P 4P 5P 6P 7P 8P 9P 10P What is the angular distance from the north celestial pole to the point on the sky called the vernal equinox? To the summer solstice?12P 13P 14P Arrange the following in order of increasing apparent brightness: Sirius; a full moon: Polaris; Venus; the Sun; the faintest star you can see without a telescope Arrange the following in order of increasing length of time: one precession cycle; one rotation of Earth; one revolution of Earth around the Sun; one revolution of the Moon around Earth; any one of Earths four seasons Find the Big Dipper in the star trails photograph on the left side of The Sky Around You.Look at The Sky Around You, item 1a. In the looking south illustration, is Canis Major a circumpolar constellation? Why or why not?3LL 4LL 1RQ 2RQ 3RQ 4RQ 5RQ 6RQ 7RQ 8RQ 9RQ 10RQ 11RQ 12RQ 13RQ Why do solar eclipses happen only at new moon? Why not every new moon?15RQ 16RQ What is the angular diameter of the Moon in the third-quarter phase? What is the shortest/longest angular distance from the horizon to the Moon in the third-quarter phase when the time is midnight or noon?Why cant the Moon be eclipsed when it is halfway between the nodes of its orbit?19RQ 20RQ 21RQ 22RQ Pretend the Moons orbit around Earth is a perfect circle. How long does it take in units of days for the Moon to move 90 degrees relative to the stars? Is this number dependent on the synodic period or the sidereal period?2P 3P 4P 5P 6P 7P 8P 9P 10P 11P Examine the list of upcoming lunar eclipses in Table 3-1. What fraction of years have two eclipses?13P 14P 15P When will the eclipse described in Problem 15 next be total as seen from Canada?17P 18P 1SP 2SP 1LL 2LL 3LL 4LL 5LL 6LL 7LL 8LL 9LL 10LL 11LL 1RQ 2RQ 3RQ 4RQ 5RQ 6RQ Which two-dimensional (2D) and three-dimensional (3D) shapes did Plato and Aristotle consider perfect? Give an example of a 2D and 3D nonperfect geometrical shape.8RQ 9RQ 10RQ 11RQ 12RQ 13RQ 14RQ Assume the night is clear and the Moons phase is full so you can see it all night long. Why would you expect the Moon to show parallax during the night? How would you measure it?16RQ 17RQ 18RQ 19RQ 20RQ 21RQ 22RQ How did the Alfonsine Tables, the Prutenic Tables, and the Rudolphine Tables differ?24RQ 25RQ 26RQ 27RQ Draw and label a diagram of the western horizon from northwest to southwest and label the setting points of the Sun at the solstices and equinoxes for a person in the Northern Hemisphere. (Hint: See Figure 3 in the Chapter 2 Concept Art: The Sky Around You and Figure 4-1.)2P 3P 4P 5P 6P 7P One planet is three times farther from the Sun than another. Will the farther planet take more, less, or the same amount of time to orbit the Sun? Will the closer planet orbit slower, faster, or the same speed? How much longer will the farther planet take to orbit than the closer planet? If the closer planet is located at 10 AU, how far is the farther planet, and what are the two planet's names?9P 10P 11P 1SP 2SP 1LL 2LL What three astronomical objects are represented here? What are the two rings?4LL 1RQ 2RQ 3RQ 4RQ 5RQ 6RQ 7RQ 8RQ 9RQ 10RQ 11RQ 12RQ 13RQ 14RQ 15RQ 16RQ 17RQ 18RQ 19RQ 20RQ 21RQ 22RQ 23RQ 24RQ 25RQ 26RQ 27RQ 28RQ 29RQ 30RQ 31RQ 32RQ 33RQ Why is the period of an open orbit undefined? 35RQ 36RQ 37RQ 38RQ 39RQ 40RQ 41RQ 42RQ An astronomy textbook is to be dropped from a tall building on Earth. One second after dropped, what are the textbook’s speed, velocity, and acceleration? After 2 seconds? After 3 seconds? The book hits the ground; what are the book’s speed, velocity, and acceleration? 2P 3P 4P 5P 6P 7P 8P 9P Describe the shape of the orbit followed by the slowest cannonball in Figure 3 of the Concept Art, pretending that the cannonball could pass freely through Earth. (Newton got this problem wrong the first time he tried to solve it.) 11P 12P 13P 14P A moon of Jupiter takes 1.8 days to orbit at a distance of 4.2 105 km from the center of the planet. What is the total mass of Jupiter plus this moon? (Note: One day is 86,400 seconds.)1SP 2SP 1LL 2LL 3LL 1RQ 2RQ 3RQ 4RQ 5RQ 6RQ 7RQ 8RQ 9RQ 10RQ 11RQ 12RQ 13RQ 14RQ 15RQ 16RQ 17RQ 18RQ 19RQ What is the role of prisms and gratings in spectrographs?21RQ 22RQ 23RQ 24RQ 1P 2P 3P 4P 5P 6P 7P 8P 9P 10P 11P 12P 13P 14P 15P 1SP 2SP 2LL 3LL 4LL 5LL 6LL 7LL 8LL 1RQ 2RQ 3RQ 4RQ 5RQ 6RQ
