This is the closest planet to the sun
Mercury
Name one of the seven spectral classes (think colors)
Blue, blue-white, white, yellow-white, yellow, orange, or red
All stars, both low-mass and high-mass, start as this interstellar cloud made of gas and dust
(Stellar) Nebula
At the end of a high-mass star's life, it will undergo an explosion called this:
Supernova
Where does pressure come from to push against the star's gravity?
Nuclear Fusion
What are the first four planets known as?
Inner Planets or Rocky Planets
This is the hottest kind of star
Blue Supergiant
Low-mass stars will only fuse up to this element throughout their whole life
Carbon
After a star explodes, it becomes one of two things. Name either of the two possibilities.
Neutron Star or Black Hole
Which fusion track is used in low mass stars
Proton-Proton Chain
A "belt" composed of this object is found between Mars and Jupiter
Asteroid (belt)
The Sun is this kind of star
Yellow Dwarf
Once a white dwarf burns out, it will become this type of star, which does not yet exist in the universe
black dwarf
High-mass stars fuse up to what element?
Iron
Which fusion track is used in high mass stars
CNO Cycle
Name on place
Kuiper Belt or Oort Cloud
This is the diagram which graphs all stars based on their magnitudes, luminosities, and temperatures
Hertzsprung-Russell Diagram (HR Diagram)
When fusion from hydrogen to helium stops, the main sequence star expands into this type of star
Red Giant
Both low-mass and high-mass stars undergo this phase, in which they are a "baby star", where there core is not yet hot enough for fusion to occur
Protostar
What is the phenomena where gas pressure counteracts gravitational pressure
Hydrostatic Equilibrium
Who composed the laws of Planetary Motion?
Johannes Kepler
What exactly is an O V Star? Think Morgan-Keenan System.
When helium fusion stops, the star begins to eject a bunch of gas and dust into the interstellar medium. What is this cloud of gas and dust called? (two word answer required)
Planetary Nebula
While the core of a high-mass star collapses, what forms? (hint: it's pushing outwards while gravity pushes in)
a (shock)wave/Remnant
Name 2 Elements of a Black Hole
Answers may include:Accretion Disk, Relativistic Jets, Event Horizon, Singularity
