This is what would happen to the planets if gravity ceased to exist but they still stayed together.
They would float off into space.
200
The type of electromagnetic radiation that travels the fastest.
They all travel at the same speed
200
This is what happens in the core of a high mass star that will cause it to go supernova
the production of heavy elements causes it to collapse and then explode
200
The shape of the orbits that the planets travel in around the sun
ellipse

300
This is how the sun rotates that is different from the planets
the equator rotates faster

The two forces that keep the planets revolving around the Sun
Gravity and Inertia
300
This how scientists use light know that the Andromeda Galaxy will eventually collide with the Milky Way Galaxy.
The blue shift
300
Compared to the Sun, the star in the HR diagram is the brightest and coldest.

According to the Big Bang Theory, how are galaxies moving in the universe?
Away from each other
400
Phase of the moon shown in the diagram
Gibbous
400
Dark areas on the sun that are cooler and indicate high solar activity.
Sunspots
400
This is what would happen to the planets if inertia suddenly ceased to exist.
They would be pulled into the Sun
400
The change in wavelength or frequency of a wave as something moves towards or away from you is known as this.
The Doppler Effect
400
A planet found in the "Goldilocks Zone" is likely to be revolving around a star in this stage of it's life.
Main Sequence
