Kepler's Laws
The location on its orbit where a planet's velocity is the greatest.
What is the perihelion?
The type of star the Sun will be when it is finished fusing all of the hydrogen into helium in its core and begins to fuse hydrogen outside its core.
What is a red giant?
The color of the stars with the highest temperature.
What is blue?
It is the force that would increase by inreasing the mass of a satellite or decreasing the distance between the satellite and the Earth.
What is gravity?
The location on its orbit where a planet's velocity is the lowest.
What is aphelion?
The type of star the sun will be at the end of its life when all fusion has stopped.
What is a white dwarf?
The color of the stars with the lowest temperature.
What is red?
It would happen if the mass of a satellite were increased.
What is the gravitational force would increase?
Planets orbit the Sun in this type of shape, not quite a circle and not a straight line.
What is an ellipse?
An explosion-like event that occurs just before the formation of a neutron star from a massive star.
What is a supernova?
The location of the Sun on a Hertzsprung-Russell diagram.
What is the main sequence?
It would happen if the mass of a satellite were decreased.
What is the gravitational force would decrease?
The time it takes a planet to travel around the Sun, measured in a year.
What is the orbital period?
The final form of a very massive star that consists of a very small, very dense mass.
What is a black hole?
The two most abundant gases found in main sequence stars.
What are hydrogen and helium?
It is what happens when the distance between the satellite and planet is increased.
What is the gravitational force decreases?
The characteristic that determines the length of a planet's orbital period.
What is distance from the Sun?
The beginning of a star, often consists of a matter left over after the death of another star.
What is a nebula?
The types of stars, found in the lower right of a Hertzsprung-Russell diagram, that are dim and cool.
What are red dwarfs?
It is what happens if the distance between a satellite and planet is decreased.
What is gravitational force increases?
In Kepler's equation P2 = a3, it is the value of P.
What is orbital period?
The two forces that keep a star stable and on the main sequence.
What are gravity and fusion?
The types of stars, found on the upper right of the Hertzsprung-Russell diagram that are bright and cool.
What are red giants?
The two ways that the gravitational force between a satellite and the Earth could be decreased.
What are increase the distance and decrease the mass?
