Astrophysics and Space Science: Sun, Stars, Exoplanets, and Cosmology Exam questions and answers How does the Sun’s method of producing energy differ from the method used in human- made nuclear power plants? The sun produces energy by nuclear fusion (hydrogen nuclei fuse into helium) nuclear power plants produce energy through nuclear fission (splitting heavy atoms like uranium) If a newly discovered comet has a highly elongated orbit, moves retrograde, is steeply tilted relative to the ecliptic, and takes about 2,000 years to orbit the Sun, where did it most likely originate? The Oort Cloud Which of the following can occur when the suns activity increases An increase in sunspots, solar flares, and coronal mass ejections, which can cause stronger auroras and disrupt satellites, communications and power grids on Earth The transit method for detecting exoplanets is most effective for Large planets that orbit close to their stars and whose orbit are aligned edge- on so they pass in fr
