Planets
This is the order of the Inner planets coming away from the Sun.
What is Mercury, Venus, Earth, and Mars?
The galaxy that our solar system is a part of-
What is the Milky Way?
This is what a group of stars that form a pattern is called-
What is a constellation?
This is the first stage of a star when it is only a cloud of dust and gas-
What is a Nebula?
Cooler, dark areas on the sun's surface are called this
What are Sunspots?
This is the order of the outer planets starting just past the Asteroid Belt-
What is Jupiter, Saturn, Uranus, and Neptune?
The most accepted scientific theory for the origin of the universe-
What is the Big Bang?
The hottest stars are this color and the coolest stars are this color-
What is blue for the hottest and red for the coolest?
90% of all stars in space are in this stage-
What is the Main Sequence?
These are explosions on the surface of the sun-
What are solar flares or prominences?
This compares the size of the inner planets to the size of the outer planets-
What are the inner planets that are smaller and the outer planets are MUCH bigger?
The shape of the galaxy that we live in-
What is a spiral galaxy?
Constellations that are visible all year long because they appear to "circle" Polaris-
What is circumpolar?
This is the stage a low mass star moves into when it uses up its supply of Hydrogen and expands in size-

In nuclear fusion in the core, this is being fused into this-
What is Hydrogen into Helium?
The number of moons is greater for these planets. (Inner or outer)
What are the outer planets?
If a galaxy is not spiral or elliptical, it is classified into this group-
What is Irregular?
A star has this kind of magnitude if it appears brighter just because it is closer to the Earth-
What is the apparent magnitude?
When a high mass star collapses violently and explodes it is called this-
What is Supernova?
The lowest layers of the sun's atmosphere-where light are produced-
What is the photosphere?
The reason that Venus has higher temperatures than Mercury!
What is the dense atmosphere that holds in the heat? (the greenhouse effect)
They think that this is in the center of the Milky Way galaxy-
What is a supermassive black hole?
Stars that show a redshift in the spectrum demonstrate that they are moving this direction-
What is away from us?
In the largest of the high mass stars, this is the final stage-
What is a Black Hole?
This is the layer of the sun's atmosphere above the photosphere-
What is the chromosphere?
