We know that Mercury has very minute quantities of hydrogen, helium, etc. But the solar wind on Mercury is strong that it does not allow the Atmosphere to get thicker there. Thus there isn't any atmosphere on the sun-facing side, but there is an Atmosphere on the non-sun facing side.

What does dense atmosphere mean?
Thick air. Planets like Venus, Jupiter, Saturn, Neptune and Uranus have a very dense atmosphere.
Why are the Jovian planets so much larger than the terrestrial planets?
No, they are less dense as the majority of their volume is composed of very light hydrogen gas. A jovian planet may have a core that is denser than that of a terrestrial planet but, as this is dense, it is not all that large. The hydrogen atmosphere is very large and therefore anti-dense (if you know what I mean). The lightness therefore dominates.
How dense is gold?
very very dense :)
What are the properties for the solar system's planets?
the inner planets (Mercury, Venus, Earth, Mars) all have rocky solid surfaces. The outer planets (Jupiter, Saturn, Uranus, Neptune) all have gaseous atmospheres and liquid surfaces. Pluto is very dense and has a rocky surface.
What part of the rain forest is very dense?
Most of the rainforest is very dense, but the understory and canopy are both pretty dense. The canopy and the understory are both very dense but the undersrory is the most dense.
Does a planet's distance from the sun affect it's density?
Very generally, the outer four planets are less dense than the four inner rocky planets, but it's more to do with planet type rather than their distance from the sun.
Are the outer planets are much less dense than the inner planets why?
The outer planets. The four inner planets (Mercury, Venus, Earth, Mars) are similar to Earth - relatively small, and with a rocky surface. The four outer planets (Jupiter, Saturn, Uranos, Neptune) are gas giants - between 5 and 11 times the diameter of Earth, and made up mainly of gas. They don't have a solid surface you can step on - just gas that gets denser as you go deeper inside.
What is the difference between Jovian and Terrestrial planets?
Jovian planets (gas giants, ice giants) are composed of gas, mainly hydrogen and helium. They have a solid core of rocks and ice about Earth's size, around which is a dense atmosphere of gas, including liquid gases, or even solid hydrogen in the case of Jupiter. Jupiter, Saturn, Uranus and Neptune are Jovian planets. Although their slushy outer cores are very hot and dense, Uranus and Neptune are referred to as "ice giants."Terrestrial planets are much smaller, with dense metal cores, a solid crust as a surface, and comparatively thin atmospheres. In the case of Mercury, the atmosphere is blown away by the solar wind, but for Venus is it much more dense than on Earth. The terrestrial planets are Mercury, Venus, Earth and Mars.jovian planets are rocky and terrestrial planets are gasy
Why are the densities of terrestrial planets greater than Jovian planets?
Yes. The Terrestrial Planets (Mercury, Venus, Earth and Mars) are primarily composed of rock, whereas the Jovian Planets (or Gas Giants) (Jupiter, Saturn, Uranus and Neptune) are composed of gases, and thus their densities are significantly less. For example The Earth has a mean density of approximately 5.5g cm3 whereas Saturn has a mean density of 0.687g cm3 which is less than water. If you could find a bath large enough and enough water, Saturn would actually float.
Is the inner core not very dense?
The inner core is very dense. It is the densest part of the planet.
Is very salty water more or less dense than more dense?
More Dense.
If you can see Venus from earth can you see earth from Venus?
Not if you were on the surface of Venus. Venus has a very dense atmosphere which would mean you wouldn't see any planets or stars. You might just be able to make out the shape of the Sun but not very well.
