  1. Now that Pluto has lost its planet status, Neptune is the most distant planet in the solar system.
  2. It’s also the smallest gas giant in our galactic neighbourhood.
  3. The strength of Neptune’s gravity is a little stronger than here on Earth.  Earth’s gravity is 9.807 m/s², and Neptune’s gravity is 11.15 m/s².
  4. The weather is nothing to write home about — it has the strongest winds in the solar system at over 2,100 km/hour!
  5. If that wasn’t bad enough it’s also the coldest with a typical temperature of -221 Celsius.

  2. Triton is Neptune’s largest moon and it’s thought that the strength of its gravity pulled it away from the Kuiper Belt and held it in orbit around Neptune.
  3. It’s predicted that in several billion years Triton will be smashed to bits by Neptune’s gravity leaving a highly visible ring.
  4. NASA‘s Voyager 2 got within 3,000 km of Neptune’s North Pole in 1989.
  5. The Great Dark Spot on Neptune was thought to be a storm or giant cloud, and can no longer be seen by the Hubble Space Telescope.
  6. Whilst Neptune’s gravity is only 17% stronger than on Earth, you wouldn’t be able to stand on the surface because it’s just a big pool of fluid.
