Quizplus · Accepted Answer

The HR diagram shown in the figure suggests that the object is an open cluster. This is because open clusters are groups of young stars that are still on the main sequence, which is the band seen in the center of the HR diagram. The spread of stars in the diagram also indicates that the object is an open cluster, as they tend to have a range of masses and ages. Elliptical and spiral galaxies tend to have less distinct HR diagrams, while globular clusters tend to have a more concentrated HR diagram with a well-defined turnoff point.
