1. Our Solar System Reviewing from yesterday

2. What is a Planet? definition for a planet is now officially known as a celestial body that (as of 2006) (a)is in orbit around the Sun (b)has enough mass for its self-gravity to overcome rigid body forces so that it assumes a nearly round shape (c)has cleared the neighborhood around its orbit

3. Dwarf Planet is a celestial body that (a)is in orbit around the Sun (b)has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a nearly round shape (c)has not cleared the neighborhood around its orbit (d)is not a satellite.

4. Plutoid Same as a dwarf planet but… must orbit farther away than Neptune Named after Pluto –2005 demoted to a dwarf planet –2008 renamed as a plutoid –Because its orbit crosses that of Neptune’s Pluto's story... in a nutshell!

7. Space Tech Cont’… CoRot French Telescope –Launched December 2006 Kepler Space Telescope/Mission –March 2009 NASA-Exoplanet Timeline

8. True or False All Planets orbit around the Sun Planets do not need to have self-gravity Dwarf planets are outside of our solar system Scientists have not discovered any exoplanets
