Stars and HR Diagram Review S.C.8.E.5.5

The graph shows the relative sizes and surface temperatures of four groups of stars. The surface temperature of the stars is measured in Kelvin (K). The Sun is part of the main sequence group.

According to the graph, the Sun is best described as…

• Massive sized, with a surface temperature of approximately 20,000 K.

• Massive sized, with a surface temperature of approximately 10,000 K.

• Average sized, with a surface temperature of approximately 8,000 K.

• Average sized, with a surface temperature of approximately 6,000 K.
