The only outer planet without a thick atmosphere is Uranus. It has a thin atmosphere composed mostly of hydrogen and helium with traces of methane.
The atmosphere of Venus is made up of primarily of carbon dioxide. Thick clouds of sulphuric oxide and carbon dioxide completely cover the planet.
Venus has a thick atmosphere consisting mainly of carbon dioxide with traces of sulfuric acid.
well there are no planets like that
Venus has an atmosphere that is so thick and dense that it is always cloudy. The clouds are composed of sulfuric acid droplets that completely obscure the planet's surface from view.
Jupiter
Venus.

Venus and the four outer planets all have a very thick and massive atmosphere.
I'm guessing you meant the planet with the only moon with a THICK atmosphere, since many moons have an atmosphere, although in very small amounts. If that's the case, then the answer is Saturn, with Titan as its moon, which is the only moon that have a thick atmosphere.
Venus has a very dense atmosphere composed mostly of carbon dioxide. This thick atmosphere traps heat, making Venus the hottest planet in our solar system.

Earth
The only outer planet without a thick atmosphere is Uranus. It has a thin atmosphere composed mostly of hydrogen and helium with traces of methane.
Mercury, while being the closest planet to the sun, has a very thin atmosphere, not allowing it to capture the heat. Venus has a very thick atmosphere, and therefore captures more of the heat from the sun.
Venus has a very thick atmosphere. Even though it is similar size to Earth, no one could survive on Venus' surface as the atmosphere has a much higher pressure meaning that we would be crushed and burned!
