EduNinjaDraw the main components of the Hertzsprung–Russell diagram (HR diagram)
This is an incomplete Hertzsprung-Russell diagram.
Which of these is in the shaded area of the diagram?
black holes
main sequence stars
neutron stars
protostars
On the diagram, draw the area to show the position of white dwarf stars. Label this area WD.
On the diagram, draw the area to show the position of red giant stars.
Label this area RG.
The Hertzsprung-Russell diagram shows stars classified into different regions.
The boxes give four points, A, B, C and D, and four star classifications.
Draw lines connecting each point to the correct star classification.

The diagram is an incomplete Hertzsprung-Russell diagram which astronomers use to compare stars.
The box contains words to identify the shaded areas P, Q and R on the Hertzsprung-Russell diagram.
Use words from the box to identify P, Q and R.
P Q R
Explain which side of the diagram contains stars with the highest surface temperature.
The Hertzsprung-Russell (HR) diagram shown can be used to classify stars.
Three regions in the HR diagram are labelled P, Q and R.
The boxes show the three regions and different astronomical objects.
Draw a straight line from each region to the type of astronomical object contained in that region.
This question is about stars.
The diagram shows an incomplete Hertzsprung-Russell (H-R) diagram.
Label the axes on the diagram.
There are three shaded areas on the diagram.
State the name of the shaded area that contains the Sun.
Which star is a white dwarf?
At a standard distance from the Earth, which star is brighter than the Sun and has a greater surface temperature than the Sun?
This question is about stars.
The evolution of stars can be shown on a Hertzsprung-Russell diagram (HR diagram).
Complete the HR diagram by
- labelling the x-axis
- completing the absolute magnitude scale
- drawing the main sequence, red giant and white dwarf regions
The Hertzsprung-Russell diagram shows the relationship between the absolute magnitude and colour of stars.
The position of the Sun is shown on the Hertzsprung-Russell diagram.
Star W is a white dwarf.
Add a W to the Hertzsprung-Russell diagram to show the position of star W.
Star X is a red giant.
Add an X to the Hertzsprung-Russell diagram to show the position of star X.
Star Y is a main sequence star that is much larger than the Sun.
Add a Y to the Hertzsprung-Russell diagram to show the position of star Y.
Star Z has the same surface temperature as the Sun, but would be dimmer than the Sun if it were the same distance away from Earth as the Sun.
Add a Z to the Hertzsprung-Russell diagram to show the position of star Z.
The Moon is the brightest object in the night sky.
Suggest why the Moon cannot be shown on the Hertzsprung-Russell diagram.
