Solar System Part 1
The Central point of our Solar System
What are small, irregular bodies in orbit around the Sun between Mars and Jupiter in the asteroid belt.
Asteroids
Name the four inner planets in order
1. Mercury
2. Venus
3. Earth
4. Mars
Name the four out planets in order.
Jupiter, Saturn, Uranus, Neptune
What is an invisible force that pulls objects toward each other?
Gravity OR Gravitational Pull
What has enough mass to form a spherical shape that orbits the sun?
Planets
What is made of ice mixed with dust, come from cold outer regions of the solar system and orbit the Sun in long narrow trails.
Comets
What is the core of these planets made of?
Iron (metallic core)
When forces pull objects together, we call those forces what? (Think Valentines Day)
Attractive Forces
What are objects that naturally orbit around planets?
Moons
Commonly called shooting stars and usually will burn in the atmosphere.
Meteors
Describe the surface of the inner planets.
Rocky, solid, land
What type of atmosphere do the out planets have?
Thick atmosphere
What is the measurement of the amount of MATTER in an object called?
Mass
Dawarf Planets
Small space rocks that have not entered the earth's atmosphere
Meteoroids
Out of the four inner planets, which one has the most moons and how many?
Mars has 2 moons.
How do the outer planets get their banded/striped pattern?
Rotate faster than rocky planets.
If distance increases, then what happens to the force of gravity?
decreases
What has a strong gravitational pull that keeps all the other objects together in an organized system?
Sun
What gets passed the earth's atmosphere and eventually hits the ground causing damage?
Meteorites
Why are Mercury and Venus the only planets with no moons?
Because they are the closest to the sun.
What do the outer planets have that the inner planets don't have?
Rings of asteroids
A person that weighs 150 pounds on the earth might only weigh 95 pounds on the moon. Explain why gravity is stronger on earth than it is on the moon.
Because earth has more mass than the moon.
Because the moon has less mass than the earth.
