  3. The Discovery of Neptune • Neptune was discovered on September 23, 1846. • It was discovered by German astronomer Johann Gottfried Galle, and astronomer student Louis d’Arrest.

  4. Neptune’s Interior Neptune’s interior make-up is primarily methane ice, just as Uranus’ is. Heat generated within Neptune helps form the unusual winds of the atmosphere.

  5. Neptune’s Atmosphere • Neptune’s composition consists of hydrogen, helium, water and minerals known as silicates. • Neptune also has 3 basic storms known as the Great Dark Spot, the Small Dark Spot, and Scooter.

  6. Neptune’s year is 165 Earth years. Its day is 16 hours and 7 minutes.

  7. DATA Diameter: 30,500 miles Distance from the Sun: 2,798,800,000 miles Mass: 5% of Jupiter’s mass [102,000,000,000,000,000,000,000,000 kg] Surface Gravity: 1.14 times the gravity on Earth Average Temperature: -218 degrees Celsius Length of Sidereal Day: 16 hours and 7 minutes Length of a year: 165 Earth years Observed Moons: Triton, Thalassa, Despina, Galatea, Larissa, Proteus, Nereid, Naiad, Halimede, Sao, Lasmedeia, Pasamathe and Neso

  8. Facts about Neptune • Neptune does have rings. • It has 13 moons that have been named. • Neptune has the strongest wind speeds in our solar system, they can be up to 2,000 km/hour. • One of Neptune’s moons Triton has a retrograde orbit.

  9. More Facts About Neptune • Neptune is the eighth planet from the sun. • Neptune is more that 2 billion miles from Earth. • Neptune orbits the sun every 165 years. • The largest storm on Neptune is known as the Great Dark Spot and would nearly cover the Earth if on our planet.
