Neptune is very similar to Uranus. It''s made of a thick fog of water, ammonia, and methane over an Earth-sized solid center. Its atmosphere is made of hydrogen, helium, and methane. The methane gives Neptune the same blue color as Uranus. Neptune has six rings, but they''re very hard to see.
Mercury is slate gray while Venus is pearly white, Earth a vibrant blue, and Mars a dusky red. Even the gas giants are different, Neptune and Uranus an opaque blue, while Jupiter and Saturn are
Dreaming of blue. Orbiting at a distance of roughly 2.8 billion miles from the sun, Neptune is the furthest planet yet discovered in our solar system (that is, after Pluto''s reclassification as
The planet''s rich blue color comes from methane in its atmosphere, which absorbs red wavelengths of light, but allows blue ones to be reflected back into space. Neptune was the first planet located through mathematical calculations.
Neptune, also known as the Blue Giant for its large size and vivid color, is the outermost planet in our Solar System. It joins Uranus, Saturn, and Jupiter as one of the giant planets. Giant planets are unimaginably huge, stunningly beautiful, and sometimes a little weird.
Our solar system ''s blue gas giant is far larger than Earth, at more than 17 times Earth''s mass and nearly 58 times Earth''s volume, according to NASA. Neptune''s rocky core is surrounded by a
More than 30 times as far from the Sun as Earth, Neptune is the only planet in our solar system not visible to the naked eye. In 2011 Neptune completed its first 165-year orbit since its discovery in 1846. Neptune is so far from the Sun that high noon on the big blue planet would seem like dim twilight to us.
Neptune: The Blue Planet, Level 1 | Neptune: The Blue Planet, Level 2. The site has information for students about this very cold and distant planet.
Neptune is the only planet in our solar system not visible to the naked eye. In 2011 Neptune completed its first 165-year orbit since its discovery in 1846. Neptune is so far from the Sun that high noon on the big blue planet would seem like dim twilight to us.
Neptune is the eighth planet from the Sun and the farthest known planet in the solar system. It lies on the inside edge of the Kuiper Belt, a large and rocky region of the solar system that contains the dwarf planets Pluto, Haumea, Makemake, and Eris. Compare the sizes and order of the planets.
