Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
Name 2-3 moon phases
the kind of galaxy that the Milky Way is
what is a spiral galaxy?
the two factors that determine the strength of gravitational attraction between two objects
mass and distance
list the four main forces affecting flight
Lift: pushes the airplane up
Gravity: pulls the airplane down
Thrust: pushes it forward (from your throw)
Drag: air resistance that slows it down
The main differences between the inner and outer planets
Inner= terrestrial, warmer
Outer= gas giants, cold
describe the difference between rotation and revolution
Rotation= object spins on axis
Revolution= object spins around something else
lenticular, elliptical, irregular, seyfert
the term that explains how a massive object, like a galaxy or black hole, bends the path of light from distant stars or galaxies behind it
gravitational lensing
name and say the purpose of two or more parts of a plane
Wings: help the plane stay up
Tail: keeps the plane steady
Rudder: helps turn left and right
Elevators: help the nose go up or down
Ailerons: help the plane tilt its wings
Engines: push the plane forward
The name if the solar system model with the sun in the middle
what is heliocentric?

Newtons 3rd law
every action has an equal and opposite reaction
the model of the solar system used long ago and says that the earth is in the centre
what is geocentric?
the traits stars are measured by
what is mass, luminosity, and temperature?
how many stars are in the milky way?
100-400 billion
describe a spectroscope or how it works
Star spectroscopy is like reading a star's "fingerprint" by splitting its light into a spectrum to see dark lines.
It uses a prism to analyze a star's light. Unique patterns of missing colors (absorption lines) tell astronomers what elements are present.
Can tell us temperature, elements present, motion, size, and age,
the force a rocket has to overcome in order to actually fly, uses propulsion to do this
what is gravity?
name two layers of the sun
Core
Radiative Zone
Convection Zone
Exterior
Photosphere
Chromosphere
Corona
the name of the graph that stars are plotted on
what is the Hertzsprung Russell Diagram?
what is a nebula?
A nebula is a huge cloud of gas and dust floating in space
They’re where stars are born
describe the anatomy of a comet
The Core: This is the solid, frozen center of the comet, typically ranging (made of frozen gases)
The Atmosphere: when the comet comes closer to the sun, the gases melt and form an atmosphere around the nucleus
The Dust Tail: Made of heavier, solid dust particles released from the sublimating ice.
The Ion Tail: Formed when ultraviolet sunlight ionizes the escaping gases
name the two types of telescopes and give an example of each
what is reflector and refractor?
