The planet’s blue color comes from methane in its atmosphere, which absorbs red wavelengths of light, but allows blue ones to be reflected back into space – very much like its neighbor, Uranus. Neptune was the first planet located using math. German astronomer Johann Galle was the first to observe the planet in 1846. The planet is named after the Roman god of the sea.</p><a href="/neptune/neptune-facts/" class="link-external-false BaseButton button-primary link-external-0 display-inline-block

He used the fortune he made in the brewery business to finance his telescopes. </p><a href="/neptune/neptune-moons/" class="link-external-false BaseButton button-primary link-external-0
