Neptune’s Name
Johann Gottfried Galle Urbain Le Verrier Heinrich Lois d’ Arrest John Couch Adams Uranus’s orbit Telescope Triton
The Discovery of Neptune
Order: 8th D. from Sun: approx. 4,460,000,000-
4,540,000,000 D. from Earth: approx. 430,000,000,000
Relative Location
Mass: about 17.2 times Earth’s size (102.4E24 kg)
Volume: approx. 62,525,703,987,421 km³ Density: 1,638 kg Sink: no, composition too heavy Gravity: about 1.12 times Earth’s
Measurements/data
Orbit: 165 Earth years Rotation: about 19.1 Earth hours
Orbit/Rotation
1% Methane other 80% hydrogen, 19% helium Thick
Atmosphere
Average 73 K (-328) Tilted more than Earth (30) Over 390 degrees colder than Florida Extreme seasons
Temperature
Gas giant Windy and cold Mantle of ammonia and methane ices Core iron and magnesium Size of Uranus Dark blue Dark storms can appear
Neptune’s appearance
Similar to most gas giants Dark spots can form (storms) Similar to Jupiter’s red spots Scooter Goes around the planet
Neptune’s Weather
Four rings Inferred that rings are young and short lived Disappearing rapidly Dark Found in 1989
Neptune’s Rings
14 moons Triton- largest and has ice on it, with a thick atmosphere, in
retrograde: 1846 Nereid- third largest, distance from Neptune varies from 1,353,600 to
9,623,700 km: 1949 Naiad- smallest named moon, closest to Neptune: 1989 Thalassa- second closest to Neptune irregularly shaped: 1989 Despina- small moon near Neptune: 1989 Galatea- small moon that is close to Neptune: 1989 Larissa- non-spherical moon that is heavily cratered: 1989 Proteus- second largest moon that is dark and close to Neptune
(irregular): 1989 Halimede- retrograde: rumored to be part of Nereid: 2002 Psamathe- takes 25 years to orbit, retrograde: 2003 Sao-Kozai resonance, inclination of orbit decreases, eccentricity
increases, vice versa: 2002 Laoredeia- one of the small moons of Neptune: 2002 Neso- 48,000,000 km away, farthest moon in SS, 26.67 revolution: 2002 S/2004 N1 (unnamed) unnamed, smallest satellite: 2004
The moons of Neptune
All water present is ice Mostly in gas and rings
Water
Freeze instantly Too much pressure Winds would smash you against objects Gas giant- no true ground except core/ fall to
death
A visit to Neptune
Winds can reach 2,000 km, making it fastest winds in solar system
Causes storms (dark spots) Dissipates in a few years
