It Takes Neptune More Than A Century To Complete One Orbit



Neptune completed its first full orbit around the sun, at least since the planet was discovered, on July 12, 2011. NASA's Hubble Space Telescope took photos of the planet to commemorate the occasion, timing the snapshots so that they captured all of Neptune's sides during its 16-hour rotation.

When Neptune was discovered in 1846, it doubled the size of the known solar system, creating a boundary at 2.8 billion miles (4.5 billion kilometers) from the sun. Its seasons last the longest of any planets in the solar system, and are a stark counterpoint to Mercury's, which shift so quickly that it's impossible to determine when one ends and another begins.
