Study Notes
Neptune Overview
- Neptune is the farthest planet from the Sun in our solar system
- It is extremely cold and windy, much farther than Earth from the Sun
- Neptune is similar to Uranus
- Neptune is made of a thick gas of water, ammonia, and methane, with a solid center the size of Earth
- It takes sunlight 4 hours to travel from the Sun to Neptune at that distance
- Neptune has a blue color due to methane in its atmosphere
- Neptune has the strongest winds in our solar system
- The winds can be up to three times stronger than Jupiter's and nine times stronger than Earth's
- A large, oval-shaped storm called the "Great Dark Spot" was observed in Neptune's southern hemisphere but has since disappeared
Neptune's Orbit and Rotation
- It takes 165 Earth years for Neptune to orbit the Sun
- One day on Neptune is equivalent to 16 Earth hours (one complete rotation)
- Neptune was discovered in 1846
Neptune's Rings and Moons
- Neptune has at least 6 rings, plus 4 ring arcs that are difficult to see.
- Neptune has 14 moons
- Triton, Neptune's largest moon, orbits backward (retrograde) unlike other moons, suggesting it may have been captured
- Triton has a thin atmosphere that is getting warmer, with geysers erupting icy material above its surface that are more than 8 km high
Neptune's Exploration
- Voyager 2 visited Neptune in 1989 and gathered information about its rings, moons, and magnetic field.
- Voyager 2 found 10 new moons, 2 new rings and a stronger magnetic field than Saturn's
- Voyager 2 traveled 3 billion kilometers in nine years, which took six hours to observe Uranus and its rings and moons
- New technologies like the Hubble Space Telescope and ground-based telescopes have further enhanced our understanding of Uranus' attributes.
- New Horizons passed the orbit of Uranus in 2011
