Neptune is a giant gas planetwhich is most likely made up of various "ices" and rock.
Depending on how far along Pluto is in its orbit (path around the Sun), Neptune can be either the eighth or ninth planet. Pluto's orbit is kind of wacky, and it sometimes crosses in front of Neptune. When Pluto does this, Neptune is behind Pluto - hence, it is the ninth planet for a short time
Neptune has 8 known moons; 7 small ones and a large moon called "Triton
Neptune's blue color is the result of a gas called "methane" in its atmosphere. Like the other gas planets, Neptune has rapid winds trapped in "bands" of latitude and large storms. Neptune's winds are the fastest in the solar system, reaching 2000km/hour!
Neptune is the eighth planet from the Sunand the fourth largest (by size) of the nine planets. Neptune is smaller in size but it's heavier than Uranus
Look for Neptune! Neptune can be seen with binoculars (if you know exactly where to look) but a large telescope is needed to see anything other than a tiny disk.
