1 This is the End Image from APOD Image from APOD (credit and copyright Michael Wilson) Artists conception of Xenia and the Solar System…100AU from Sun. Note the 44 degree tilt of orbit.

2 New Horizons on its out

3 What about Uranus and Neptune –Uranus doesnt show much detail.. –About 15 Earth masses –Methane Atmosphere –Too cold for storms etc.

4 Neptune Neptune is slightly More massive Radiates its own heat Great dark spot! Radiates more heat Than its gets from sun

5 Neptune Interior

6 Bulls Eye!

7 Uranian Moons….

8 Miranda and Ariel D = 500 Km D = 1500 Km

9 Neptunes System D = 500 Km D = 1500 Km Voyager flyby Neptune and Triton

10 Neptunes System Voyager flyby Neptune and Triton Triton (2800 km)

11 Small Compared with Familiar Moons and Planets…..

12 Neptunes System Voyager flyby Neptune and Triton

13 Meet some new family members

15 What would a dwarf planet KBO look like near the sun? Image from APOD Image from APOD (credit and copyright Jimmy Westlake)

16 How out does the solar system go?

17 Artists conception of Xenia and the Solar System…100AU from Sun. Note the 44 degree tilt of orbit. Moving on to other stars….

18 A rare find..inner planets

19 The doppler method of finding planets

20 What is density? density = mass/volume Where to look for life?

21 A growth industry!
