These are areas of low temperature on the sun.
Sunspots
100
What type of galaxy is this? Why?
Irregular galaxy because it has no definite shape.
100
Name all the minor bodies of our solar system!
Meteor, meteorites, asteroids, and comets.
100
Name the inner planets of the solar system. What are they also called?
Mercury, Venus, Earth, Mars. Rocky or Terrestrial planets

This theory stated that the universe was always in its current state and was not expanding.
The Steady State Theory or Static State Theory
200
What is the name of the scale that we chart stars on?
The Hertzsprung Russell Diagram
200
Name the different types of galaxies.
Spiral, Irregular, Elliptical
200
Define the term natural satellite. Give an example.
A natural satellite is any non man made object that orbits another object. Earth and moon.
200
Name the outer planets of the solar system. What are they also called?
Jupiter, Saturn, Uranus, Neptune. Gas giants or Jovian planets.
200
What does the Big Bang Theory state?
That the universe began as a very hot, small, and dense singularity and rapidly expanded, creating the universe we know today.
300
How do we classify stars on the scale?
We classify stars based on luminosity and temperature.
300
Explain the difference between redshift and blueshift.
Redshift is when an object moving away from you, light waves lengthen. Blueshift is when light waves are seen from objects moving toward Earth.
300
Why might a telescope benefit from being outside of Earth's atmosphere compared to being on Earth?
The Earth's atmosphere can distort a telescopes reading and some wavelengths are also absorbed by the Earth's atmosphere.
300
What separates the inner and outer planets?
Asteroid Belt.
300
What two elements were created first? Why?
Hydrogen and helium because they are the simplest.

What arm of the Milky Way galaxy are we located in?
Orion

Explain the difference between meteors and meteorites. OR explain the difference between asteroids and comets.
Meteors are also known as shooting stars, they burn up as they enter the atmosphere. Meteorites are meteors that reach the Earth. Asteroids are made up of mostly rock and metal materials. Comets are made up of icy rock materials.
400
What belt is located outside of Neptune's orbit? What significant object(s) are located inside the belt?
Kuiper Belt. It contains the dwarf planet Pluto and short period comets!
400
If you have a distance of 4.5 in parsecs, what is this unit in arc seconds? Round to the nearest hundredth.
d = 4.5 = 1/p
p=.22
500
Give one detail about high mass stars and low mass stars.
Low mass stars:
Planetary nebula
white dwarf
black dwarf
High mass stars:
supernova
neutron star
black hole
500
What unit of astronomical measurement is used to measure the distance between galaxies?
Parsecs
500
Name the difference between long period and short period comets.
Long period comets have an irregular orbit that can take up to 200 years to complete its orbit. Short period comets have an elliptical orbit that take less than 200 years.
500
What is the Oort Cloud?
A hypothetical sphere that surrounds the solar system that contains millions of long period comets.
500
There are four pieces of evidence that support the Big Bang theory. Please name two of the four.
Cosmic background radiation/cosmic microwave background
the measurable expansion of the universe
the relative abundances of the different elements in the universe
the known laws of physics
