Problem 1
Assume NASA is sending a space probe to each of the following locations: a. Polaris (the North Star) b. A comet near the outer edge of our solar system c. Jupiter d. The far edge of the Milky Way Galaxy e. The near side of the Andromeda Galaxy f. The Sun List the locations in order, from nearest to farthest.
Problem 2
Use the information provided below about three main-sequence stars \((\mathrm{A}, \mathrm{B},\) and \(\mathrm{C})\) to complete the following and explain your reasoning. \- Star A has a main-sequence life span of 5 billion years. \- Star \(\mathrm{B}\) has the same luminosity (absolute magnitude) as the Sun. \- Star C has a surface temperature of \(5,000 \mathrm{~K}\). a. Rank the mass of these stars from greatest to least. b. Rank the energy output of these stars from greatest to least. c. Rank the main-sequence life span of these stars from longest to shortest.
Problem 3
The mass of three clouds of gas and dust (nebulae) are provided below. Imagine that each cloud will collapse to form a single star. Use this information to complete the following and explain your reasoning. \- Cloud A is 60 times the mass of the Sun. Cloud \(\mathrm{B}\) is 7 times the mass of the Sun. Cloud \(\mathrm{C}\) is 2 times the mass of the Sun. a. Which cloud or clouds, if any, will evolve into a red main-sequence star? b. Which of the stars that will form from these clouds, if any, will reach the giant stage? c. Which of the stars that will form from these clouds, if any, will go through the supernova stage?
