100
Groups of stars named after animals, mythological characters, or everyday objects.
What are constellations?
100
A change in wave frequency as the observer and source move relative to each other.
What is the Doppler Shift?
(aka Doppler Effect)
100
This property determines most of the other star properties.
What is mass?
In fact, all of the other aspects of a star such as its luminosity, temperature, size, density, etc., can be explained using its mass.
100
O, B, A, F, G, K, and M
What are spectral types?
100
What is the Doppler Effect?
200
These star groups appear to rotate around the pole
What are Circumpolar Constellations?
200
This phenomenon indicates that the observer & the source are moving away from each other.
What is a Red Shift?
200
This property describes a star's brightness.
What is Magnitude?
200
Temperature determines these two properties
What are luminosity and spectral type?
200
What is Parallax?
300
Ancient peoples used these star groups to know when to plant, harvest, and perform rituals.
What are Seasonal Constellations?
300
This phenomenon indicates that the observer & the source are moving towards each other.
What is a Blue Shift?
300
This property describes how bright a star appears to an observer on Earth.
What is Apparent Magnitude?
300
Nearly all stars are composed of
What are H (73%) and He (25%)?
300
What are binary stars?
400
A group of stars that are gravitationally bound to each other

400
Two distance units used in astronomy
What are light year and parsec?
Bonus: do you know a third?
400
This property accounts for a star's distance from Earth.
What is Absolute Magnitude?
400
What is an H-R Diagram?
400
What are Globular and Open Clusters?
500
Pleiades and M13 are two different types of star clusters.
What are Open Cluster and Globular Cluster?
500
The apparent shift in the position of an object caused by the change in position of the observer.
What is Parallax?
500
This property describes a star's energy output per second.
What is Luminosity?
Bonus: Do you know the units?
500
Who developed the H-R Diagram?

500
What is a star Color vs Temperature chart?
600
Two stars that are gravitationally bound together & orbit a common center of mass.
What are Binary Stars?
600
The closer the object is to the observer, the ___________________ the parallax shift.
What is larger?
600
How does mass affect a star's temperature?
What is the more massive a star is, the greater the gravity pressing inward, and the hotter and denser the star must be inside to balance its own gravity?
