Solar System Soiree
Gravity Gains
Totally Orbital
Sun and Stars
The Universe
100
This is the third rock from the Sun
What is the Earth?
100
This is the object with the greatest gravitational pull in our solar system
The Sun!
100
Orbits tend to be this shape
What is elliptical?
100
A star fuses this element to create another element (name both elements)
Hydrogen (H) and Helium (He)
100
The universe is currently....
Expanding
200
What is the "habitable zone"?
The area not too close or far from a star where a planet can have liquid water and support life
200
These two variables result in a stronger gravitational force
larger mass and shorter distance
200
This is an object that orbits a planet. For example, a Moon.
What is a satellite?
200
These are the life cycle stages of low mass star in order
Nebula - Protostar - Main Sequence - Red Giant - White Dwarf - Black Dwarf
200
The universe was once a dense, hot, bright point. This is why we no longer see that bright light.
The waves have stretched past the visible spectrum - it is now microwave radiation instead of visible light
300
This planet orbits the star the slowest.
Planet C
300
This is a measure of how much matter an object contains (is made of)
What is mass?
300
All objects in the solar system orbit in this direction
What is counter-clockwise?
300
These two forces keep a main sequence star stable
Fusion and Gravity
300
An object moving towards you is in blue-shift. Explain why.
The light waves are compressed - (shorter wavelength/higher frequency) which makes them appear blue
400
How can you tell which direction the dot is moving?
Left - it is compressing the waves as it moves into them
400
The gravitational force exerted on an object
What is weight?
400
Planet X takes 36 days to orbit its star, Planet Z takes 33 days. At its farthest point, this planet is furthest from the star
What is Planet X?
400
Why don't high mass stars 'live' as long as low mass stars?
They 'burn' through fuel too quickly. Too much gravity/pressure
400
This galaxy is moving away from you the fastest (Explain how you know)
A - the most amount of red-shift
500
Does Earth or Venus experience a weaker gravitational pull from the Sun? Why?
Earth - it's further away
500
Draw and label what would happen to a planet orbiting a star if the star suddenly disappeared.
planet must leave orbit in a straight line following it's original trajectory
500
Planet A is 5 million miles from it's star, and Planet B is 6 million miles away from the same star. Which planet has a longer orbital period? Why?
Panet B - it's further away
500
What is the solar cycle?
Flipping of the sun's poles every 11 years.
500
One piece of evidence for the Big Bang - You MUST accurately explain how your evidence supports the theory
