Sun
- The solar system = the Suns system
- Sun is more than 99% of all the matter in the solar system
- Suns gravity holds the solar system together
- Suns radiation warms the objects in the solar system
How large
Chapter 10 Other Planetary Systems
Are there other Solar System?
- If the Nebula Theory is correct, them planets form when stars form
- called extrasolar planets or exoplanets because they are exterior to our solar
system
Can we detect Exoplanets?
- Chall
Chapter 8 Jovian Planet System
Properties of Jovian planets properties
- The Jovian planets share these physical properties
- Large mass 14.5 to 318 x Mearth
- large diameters 3.88 to 11.2 x Dearth
- large volumes ( D3) 58 to 1400 x Volearth
- small avera
Chapter 9 Asteroid, Meteoroids, Comets, Dwarf Planets
Solar systems smaller objects
- Solar system has many objects smaller than the major planets
- Asteroids also called minor planets
- meteoroids
- comets
- dwarf planets (since 2006)
What are Asteroids?

Constellation are patterns of stars we see in the sky
- stars in a constellation may not be associates with each other in space they must
just appear grouped together as seen from Earth

How do we describe motion?
- Speed = change in position or location in some amount of time = m/s
- Example:
-Walking speed 1m/s
- running speed -10m/s
- driving 27.8m/s = 100km/h
- Earths orbit speed 30k
