Planet Earth - about 80%.
The Earth has an atmosphere of 78% nitrogen (and 21% oxygen).
Earth's atmosphere is mostly made up of nitrogen and oxygen; but the planet itself is more than just its atmosphere - overall Earth, like other terrestrial planets, is mostly made from rock (silicates) with a nickel-iron core. (By comparison, overall the outer gas planets are mostly made from hydrogen and helium.) By relative abundance, oxygen is also the most common element in the Earth's crust.
This one...the earth. The other planets are made up of critical gases,like methane, with frozen planets like Pluto made up of layers of frozen gases, such as a suspected layer of oxygen underneath layers of nitrogen and methane, and sulfuric gases which tend to snow out on the cold side of the planet.
Mercury has virtually no atmosphere. Planet with thinnest Venus has a extremely dense atmosphere of mostly sulphur compared to Earth. Planet with densest. Earth has a moderately dense atmosphere of nearly 3 quarters nitrogen and oxygen. Planet with 2nd from densest. Mars has a thin atmosphere of mostly carbon and some oxygen. Planet with 2nd thinnest.
Venus is believed to have its original atmosphere, composed mostly of carbon dioxide and traces of nitrogen and sulfuric compounds. This thick atmosphere has contributed to Venus having a runaway greenhouse effect, making it the hottest planet in our solar system.
Mercury
Neptune (NovaNet) There's something wrong here. Neptune is mainly a hydrogen atmosphere. Earth is the planet with a mainly nitrogen atmosphere, but the coldest is Neptune.
Titan, one of Saturn's moons, has a dense atmosphere composed mostly of nitrogen.
The Earth has an atmosphere of 78% nitrogen (and 21% oxygen).
Mostly carbon dioxide (96.5%). Most of the rest is nitrogen.
Earth is the planet that fits this description. It contains approximately 70% water on its surface and its atmosphere is primarily composed of nitrogen, with oxygen being the second most abundant gas.

It is none other than our own planet Earth, which has nitrogen and oxygen in its atmosphere.

Titan's atmosphere is 98.4% nitrogen; its parent planet is Saturn.
Mercury has virtually no atmosphere. Planet with thinnest Venus has a extremely dense atmosphere of mostly sulphur compared to Earth. Planet with densest. Earth has a moderately dense atmosphere of nearly 3 quarters nitrogen and oxygen. Planet with 2nd from densest. Mars has a thin atmosphere of mostly carbon and some oxygen. Planet with 2nd thinnest.
The atmosphere is mostly nitrogen. The atmosphere is above most of the water on Earth.
