  1. Neptune Cole Nachman

  2. Symbol

  3. Why the name Neptune? • Urbain Le Verrier discovered planet. • Claimed right to name discovery

  4. Who? When? How? • Urbain Le Verrier • September 23, 1846 • Using Mathematics -1846, John G. Galle and Heinrich d’Arrest looked for predicted planet and saw it

  5. Planet Measurements • Mass: 1.0243x10^26 kg • Volume: 6.254x10^13 kg • Density: 1.64 g/cm3 Neptune would not float in water because of its denseness. Gravity: 11.15 m/s2 acceleration

  6. Atmosphere • Thick -74% hydrogen -25% helium -1% methane

  7. Distances • Eighth from the sun (farthest) • 4,503,000,000 km from sun • 4,301,000,000 km from earth

  8. Orbit and Rotation • 164.79 years to orbit the sun -165 times longer than Earth • 19.1 hours to rotate on its on axis

  9. Temperature • Temp. range of -151.1 through -201.1 degrees celsius on Neptune • Temp. range of 10 through 20 degrees celsius on Earth • Temp. range of 18.3 through 21.1 degrees celsius in Florida

  10. Neptune’s Composition • Gas Giant Surface is not solid • Internal composition consist of: Mantle: A water, ice and rock mixture (May contain Methane). Core: 45% of mass is silicate rock

  11. Appearance Neptune is a cold, blue-colored planet. Neptune has many gas clouds, some of which are visible from outside the planet. Neptune also has many storms and powerful wind speeds (most powerful winds of all planets in solar system). A cool feature about Neptune is it’s “Great Dark Spot”. The “Great Dark Spot” is a depression in it’s atmosphere. There are also 3 faint rings.

  12. Rings • 3 main rings -Adam (outermost) -Unnamed ring (middle) -Galle(inner) • Reddish in color • 20% dust and small rocks • Discovered by “Voyager 2 Probe.”

  13. Water • Steam • Liquid water • Ice

  14. Weather • Large storms, High Winds • Rapidly Changing clouds No one knows how it gets its strong weather, being its so far away from the sun.

  15. Moons • 14 moons in total (so far) • Discovered from 1846-2013 (July 15, 2013 was the latest discovery) • Moons are extremely icy and cold!

  16. What would happen if a human visited Neptune? • Humans would freeze, because of the fact that Neptune has freezing temperatures. • Humans would choke because of the lack of oxygen on Neptune.

  17. What makes Neptune so special? • Farthest planet from sun • Smallest of Gas giants • Gravity is Earth-like • Coldest planet • No definite plans to revisit Neptune again • Windiest planet
