  3. Why it was found Neptune was found when astronomers realised that Uranus wasn’t following its orbit and decided that there must be a larger planet pulling it of course with its gravity. Two scientists, one called John Couch Adams (1819-1892) another named Urbain Le Verrier (1811-1877) managed to track down exactly where it was. In the end only Le Verrier managed to get a astronomer to find it.

  4. Moons • Neptune has thirteen known moons. • The largest moon Triton is the only known moon in our solar system that orbits its planet the opposite way the planet rotates. • Some scientists believe Triton isn't one of Neptune's original moons but was once in orbit of the sun but was pulled into orbit by Neptune’s gravitational pull unlike Nereid which scientists say is probably a original moon of Neptune. • Triton is what's known as a regular satellite. • Triton has active geysers.
