On the graph attached, plot every one of the “nearest stars” using an “∗
”
On the same graph, plot every one of the “brightest stars as seen from Earth” using a “∙
”
If the stars appear on both lists, just circle the star “ ⊗
” to represent both symbols
Compare your graph with the H-R diagram at the top of this assignment. Label each type of star on your graph. (example: label the white dwarf section, the main sequence section, etc.)
Our Sun has a temperature of 5800 K (which is 6073°Celsius) and an absolute magnitude of +4.7. Use a “⊙
” symbol to plot the location of the Sun on your diagram. Use the two tables to plot the points on the graph attached as a PDF
