∙ 12y agoMercury has a surface pressure that is near enough zero or a vacuum. This planet holds no real atmosphere at all due to its small size.
Nest would be Mars, with its very thin atmosphere of Carbon Dioxide.

∙ 11y agoMars... but not by much compared to Mercury.
If Pluto had not been demoted, it would be the clear winner.

Why does neptune have the slowest orbital velocity?

What is the lightest planet in solar system?
The least massive of the 8 major planets is Mercury. However, Saturn, with its large, deep atmosphere, is the least dense of the planets, and would actually float in water (given a really big container of water).
Why is mercury the nearest to the sun?
it is the smallest planet and therefore the lightest and easiest for the sun to bring closest into its gravity well.
Is there any special things on Saturn?
Well their is water, i think! By the way this is a random fact: Saturn is the largest and lightest planet in the universe.
