_____: Pieces of rock that revolve around the sun in an ellipse.
What is an Asteroid?????
True
What is the second step of a formation of a star?
A Protostar is the second step, a flattened disc if shrinking and spinning gas that has a large concentration of matter.
What is the second hottest interior?

How long is the lifespan of for a star generally?
Billions of years.
_____-Celestial bodies that are small and composed of ice, rock, and dust.
What is a comet?
True or False- Luminescence is how much energy is released per second.
False. Luminosity.
Temperature of the Protostar raises and Fission/Fusion occurs. Which one is correct?
Nuclear Fusion.
Sphere of light, 5th hottest form of energy released from it: Visible light; what we see on Earth.
Photosphere
After all helium has became _______ no more fusion will take place.
Carbon/Oxygen
Small bodies make of rock of metal: usually have a diameter of <1 mm
True or False- A red giant is the coldest.
True
When Fission/Fusion occurs we officially have a what?
____ Causes more energy and heat to be released causing the star to expand, which counteracts/cancels out the gravity pulling it inward.
Fusion occurs and we officially have a star. The blank answer is Fusion too.
