Characteristics
of Stars
10 Point
This is a device that makes
distant objects appear
closer.
What is a telescope?
This includes the entire range
of radio waves, infrared
radiation, visible light,
ultraviolet radiation, X-rays
and gamma rays.
What is the electromagnetic
spectrum?
This is the distance between
the crest of one wave and the
crest of the next wave.
What is a wavelength?
This is a building that contains
one or more telescopes.
What is an observatory?
This is the part of the EM
spectrum you can see.
What is visible light?
These are imaginary patterns of
stars
What are constellations?
This is color, temperature,
size, composition and
brightness.
What are the star’s
characterstics or how are stars
classified?
Astronomers use this unit to
measure distances between the
stars.
What is a light year?
This is a star’s brightness as
seen from Earth.
What is apparent brightness?
This is brightness the star would
have if it were at a standard
distance from Earth.
What is absolute brightness?
This is what H-R stands for in
H-R diagram.
What is Hertzsprung-Russell?
The Hertzprung-Russell
Diagram has these two
categories on its X axis and y
axis.
What are absolute brightness
and surface temperature?
The sun is in this section of the
H-R Diagram.
What is the Main Sequence?
This is the color cooler stars are,
like Betelgeuse.
What is the color red?
The brightest stars are located
here on the H-R Diagram.
What is the top?
This is a cloud of gas and dust
spread out in an immense
volume.
What is a nebula?
This is what a star’s life
depends on.
What is its mass?
These are the three things a
star becomes when it runs out
of fuel.
What is a white dwarf, a
neutron star or a black hole?
This is the brilliant explosion of a
supergiant star.
What is a supernova?
This is an object with gravity so
strong that nothing, not even
light, can escape.
What is a black hole?
These are the three parts of the
sun’s atmosphere.
What are the photosphere,
chromosphere and corona?
These are two forces that keep a
planet in its orbit.
What are gravity and inertia?
This is what the gas giants are
mainly composed of.
What is mainly hydrogen and
helium, much of which is in
liquid form?
This is the satellite the Soviets
launched in 1957 to start the
Space Race.
What is Sputnik 1?
The Greeks believed in this
system wherein the earth was
the center of the revolving
planets and stars.
What is a geocentric system?
Make your wager
These four groups of stars are
labeled on the HertzsprungRussell Diagram.
What are main sequence,
supergiants, giants and white
dwarfs?
