3. The Solar System is the system of the Sun and the objects that orbit it bound together by gravity
Galaxy is a massive group of stars, gas and dust, solar systems, and dark matter bound together by gravity
A universe is a large and unimaginable space of dust, gas, stars, clouds, galaxies, and life
Interesting facts….
There are other solar systems out there large distances btwn planets -----distance between Earth to Jupiter 640 days
We are in the milky way galaxy, hundreds of billions of stars in a galaxy
Universe is made of 100 billion galaxies
Dark matter --- something that has a mass or takes up space that is undetectable using astronomical equiptment ?

6. CHECK FOR UNDERSTANDING63
CHECK FOR UNDERSTANDING
Did you know? Jupiter, the largest planet in our SS, has the most moons! Guess how many?
What will happen to the force of gravity if:
Increase Red mass
Increase Blue mass
Increase distance of Red mass
Increase distance of Blue mass
Decrease Red mass & Blue mass

8. Mass
Force

9. Measuring objects in Space
Objects in space look close but they are REALLY, REALLY, REALLYYYYYYY far away
Distance from the Earth to the Moon is meters and travel would take 3 days!
Travel from the Earth to the Sun = 156 days

10. Astronomical Units (AU)
Light Year (LY)
Measures the distance between planets
Used when other measurements get to large (distance between planets)
Based off distance from the Sun to the Earth
Measures distances farther than planets in our solar system (to distant stars)
Based off distance Light travels in a year
Nothing is faster than the speed of light
63241 AU = 1 LY

11. Parsec
Measures extremely distant bodies in space distances (like between galaxies)
about 3 light years = 1 parsec
