Quizplus · Accepted Answer

A typical galaxy like our Milky Way galaxy contains stars (some with planets), gas, and dust. Planets are only a small fraction of the overall content of a galaxy. Gas and dust are also present, but stars are the most abundant component. Superclusters, on the other hand, are an even larger scale structure than galaxies, and typically contain many galaxies. Therefore, E is not the correct answer either.
