4. Background Information…  Atmospheric components : 74% hydrogen, 25% helium, 1% methane (at depth)  Diameter (km): 49,528  Average distance from Sun: 4,498,252,900 km  Mean temperature (K): 48

5. Background Information Contd.  Fourth largest planet in the Solar System  Winds on Neptune can get up to 1,200 MPH  One Neptune day is equal to 16 hours in Earth time  One Neptune year is equal to 164.83 Earth Years

6. Whoaaa, Optical Illusion!

7. Where’s Santa Claus on Neptune?  Well, Neptune has two North Poles and two South Poles because of its magnetic field.  So, if we lived on Neptune, we would get double the presents on Christmas!

8. Climate and Living Conditions…  One of the two ice giants, the other one is Uranus.  Avg. temperature, 72° Kelvin OR, -201° Celcius

9. Does Neptune Have Water?  No, it doesn’t. But, it is 74% hydrogen so if oxygen ever came along….  That’s not the only similarity that Neptune has to Earth…  Neptune also has an internal heat source!  It radiates more than twice as much energy as it receives from the Sun!

10. Moons  Neptune has 8 moons.  But, the most well known and the biggest one is Triton.  Triton has geysers that shoot ice 5 miles high into it’s thin atmosphere.  Could possibly be water under the ice  The interior of Triton is probably geologically active!!

11. Neptune Got Da Bling!  5 Rings: Galle Ring: closest to Neptune, 2,000 kilometers wide. Composed mainly of dust particles Le Verrier Ring: 113 Kilometers wide, is 53,2000 Kilometers away from Neptune. Composed mainly of dust. Lassell Ring: widest of the 5 rings width 2x that of the Galle ring. 20-40% made of dust

12. Neptune Got Da Bling!  Arago Ring: width of only 100 kilometers  Adams Ring: outermost ring, 35 kilometers wide
