Stars Rule
100
A star in its last stage that collapses in on its own gravity
What is black hole
100
The Hubble Space Telescope is powerful enough to see a star with magnitude of +6
The Hubble Space Telescope is powerful enough to see a star with magnitude of +30.
100
The distance that light travels in one year.
What is light-year
100
A group of stars that form a pattern in the sky
What is a constellation
100
Given the situation, state a rule to justify it. - When I look at a star at 8 pm it looks like it has moved when I look at it at 3 am the same night.
Rule: The sky seems to move but really the Earth is rotating.
200
A less massive star goes from white to black of these
What is dwarf (first a white dwarf, then a black dwarf in last stage).
200
A star's volume determines its path through its life cycle.
A star's mass determines its path through its life cycle.
200
A word that means giving off light .
What is luminous
200
An enormous system of gases, dust, and stars held together by gravity
What is a galaxy
200
Given the situation, state a rule to justify it. - I live in the United States and I can see the constellations Ursa Major and Ursa Minor all year long but when I went to Australia on vacation I couldn't find either constellation in the sky.
Rule: Ursa Major/Minor are circumpolar constellations in the Northern hemisphere which means you can see it all year round in that hemisphere.
300
A rapidly spinning star in its last stage.
What is a neutron star
300
The Milky Way is an irregular shaped galaxy.
The Milky Way is a spiral shaped galaxy.
300
The brightness of a star.
What is magnitude
300
A large sphere of glowing gases.
What is a star
300
Given the situation, state a rule to justify it. - Star A has a magnitude of 6 and Star B has a magnitude of 1. Star A will be dimmer (less bright) than Star B.
Rule: The higher the magnitude the dimmer the star (the lower the magnitude the brighter the star).
400
Before a star is born its starts out as a rotating cloud of gas and dust
What is nebula
400
Stars in a constellation are close together that’s why they appear to make shapes.
Stars in a constellation are NOT close together but they appear to make shapes when viewed from Earth.
400
A measure of how much light-energy is given off by something, such as a star.
What is luminosity
400
When a star can be seen all year round it is known as this
What is circumpolar
400
Given the situation, state a rule to justify it. - Star F is 400 Ly from Earth while Star G is 59 Ly from Earth. Star G will appear to be the brightest.
Rule: The greater the distance from Earth the dimmer the star (The closer the distance from Earth the brighter the star).
500
As stars grow old they expand and grow cooler and less bright to form this.
What is red giant
500
The location of a constellation depends on the magnitude.
The location of a constellation depends on the season.
500
Apparent magnitude is the same as this because one is a measure of the other
What is apparent brightness
500
The first stage in a stars life cycle
What is a protostar
500
Star P is a blue super giant star and Star Q is a red super giant star. Star P is hotter.
Rule: The cooler looking the color (blue/white) the hotter the star. Blue/White are hotter on the stellar spectrum than a yellow/red star.
