On a planet
What are galaxies made up of?
The sun and Earth
humans
planets
Gas, dust, and billions of different shaped stars.
What do elliptical galaxies look like?
no definite shape
a nucleus of bright stars and two or more spiral arms
spherical or flattened disks
round ball shape
What do spiral galaxies look like?
a nucleus of bright stars and two or more spiral arms
spherical or flattened disks

What is a light year defined as?
the fundamental unit of length in the metric system, equal to 100 centimeters or approximately 39.37 inches.
a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km (nearly 6 trillion miles).
a unit of linear measure equal to 5,280 feet
a metric unit of measurement equal to 1,000 meters
Why do scientists use light years to measure distances?
They think it is cool
it sounds smart
miles would not work because the universe is too big
distances in space are so large, they must use as large conventional measure.
What is the universe made up of?
mass and distance
mass and energy
energy and distance
space and planets
How do astronomers decide if a galaxy is expanding?
amount of gravity
number of planted
color of light emitted
acceleration rate

The movement of moons is based on ___________ around their planets and __________ on their axis.
orbit; temperature
revolution; rotation
time; rotation
rotation; revolution
_________are rocky bodies that orbit in a region in the solar system between Mars and Jupiter. They vary in size and shape. Movement is based on their revolution around the Sun. Some ________ outside the belt have orbits that cross Earth’s orbit, which require scientists to monitor their positions.
asteroid
comet
meteor
meteorite
________have a main body or head (ice, methane and ammonia and dust) and a tail that emerges as the comet gets closer to the Sun during its orbit.
The effects of the solar winds result in the tail always points away from the Sun.
________ have long, narrow, elliptical orbits that cause them to cross paths with other objects in the solar system.
Most__________ originate from regions of the solar system that lie beyond the orbit of Neptune.
planet
comet
meteor
asteroid

Meteors
Planets
Asteroid
Comet
What is it called when a meteor strikes Earth?
comet
meteorite
meteoroid
asteroid
_______ are studied in relation to the planet they orbit. Not all planets have them. Most are rocky bodies covered with craters, but some have unique characteristics. Movement of _______ is based on revolution around their planets and rotation on their axis.
space ships
comets
moons
