Special Attractions and the Great Dark Spot
Other Interesting Features
Because Pluto's orbit is so eccentric, it sometimes crosses the orbit of Neptune making it the furthest planet from the sun. Neptune has an eternal heat source - it radiates more than twice as much energy as it receives from the sun. One of the rings on Neptune appears to have a twisted structure. Neptune also has 13 known moons close to the planet.
Rings...yes, rings!!!
The Great Dark Spot
However, in 1994, to scientists dismay, the Hubble Space Telescope showed Neptune clearly... with no spot! The scientists' believed that the spot had dissipated, or had possibly been masked by other elements of the blue planet's surface. But within the next few months, the Hubble Space Telescope showed another spot that had appeared in the northern hemisphere. That interestIng situation proved that Neptune's atmosphere changes rapidly, perhaps because of the temperature, or the special clouds.
