Neptune

Addison Davis 5/6/19

Untitled Slide

  • "When the icy planet is closest to the sun, it lies "only" 2.77 billion miles (4.46 billion km). At its farthest, it passes 2.82 billion miles (4.54 billion km) from the star. Although Neptune is the eighth most distant planet, it was not always. The dwarf planet Pluto occasionally dips inside of Neptune's orbit." .

  • "Neptune has 17 times as much mass compared to the Earth. ... The surface gravity on Neptune (if it actually had a surface that you could stand on) is only 14% stronger than the pull of gravity on Earth. You would have a difficult time noticing if you were standing on the surface of Neptune compared to the surface of Earth."

  • "Neptune has an incredibly thick atmosphere comprised of 74% hydrogen, 25% helium and approximately 1% methane. Its atmosphere also contains icy clouds and the fastest winds recorded in the solar system. Particles of icy methane and minor gases in the extremities of the atmosphere give Neptune its deep blue color."

  • "With an average orbital speed of 5.43 km/s, it takes Neptune 164.8 Earth years (60,182 Earth days) to complete a single orbital period. This means, in effect, that a year on Neptune lasts as long as about 165 years here on Earth."

  • "Neptune's atmosphere is made from about 80% hydrogen and 19% helium. It also contains a small amount water and methane, which give rise to the green-bluish color. The dark blue and bright white features of the atmosphere help distinguish Neptune from Uranus. The thin cirrus-like white clouds contain methane ice."

  • "The satellite discovered Neptune's rings and six of the planet's moons — Despina, Galatea, Larissa, Naiad, Proteus and Thalassa. An international team of astronomers relying on ground telescopes announced the discovery of five new moons orbiting Neptune in 2003."
