Venus has a very thick atmosphere, made up mostly of carbon dioxide. Carbon dioxide, just like on Earth, is a greenhouse gas, meaning it traps the sun's heat. Venus can't release all the heat energy it absorbs from the sun back into space, causing the atmosphere and planet surface to heat up.
Mercury, on the other hand, has no atmosphere, and the side farthest from the sun is always exposed to the deep cold of space. This allows the planet surface to bleed off the heat it absorbs.

∙ 13y agoVenus has an extremely thick layer of clouds that traps the suns heat. Mercury on the other hand, does not. Mercury looses the energy it gained from the sun during the day soon after the sun sets, since there is nothing on Mercury to retain that energy. Venus has clouds that are able to retain heat like a blanket.

∙ 13y agoWhile Mercury is closer to the Sun, the atmosphere of Venus traps the heat under the highly toxic levels of CO2, which could be something to say that Global Warming is caused by CO2, but is completely irrelavant, since there has been no unnatural change in the Earth's natural cycle of Global Coolings and Global Warmings since the invention of mass production, the greatest manufacturer of CO2 in the modern world. Finishing up your question, the reason why Venus' surface is hotter than Mercury's is due to an atmosphere of Carbon Dioxide, which allows heat into the planet's atmosphere, but doesn't allow it to escape.

What planet has high temperatures due to the runway greenhouse affect?
It’s actually Venus.
What is the warmest planet out of Jupiter Venus Mercury Mars or Earth?
Mercury. When the Sun is at it's peak, surface temperatures can reach 700 F. (370 C.). Improvement: Venus has the highest temperatures.
Why do you think that scientists discuss manned missions to mars but not to venus?
Scientists discuss manned missions to Mars because it would be much easier to send humans to Mars because the conditions on Mars are much less extreme than those on Venus. For example, surface temperatures on Mars range between -125ºC to 35ºC while those on Venus range between 450ºC to 475ºC.
Venus mars and mercury in order of size?
The order of Mercury ,Venus and Mars by size is: Mercury ,Mars and Venus
Venus is located between the planets Earth and?
Earth's orbit is intermediate between the orbits of Venus and Mars. Earth is an average distance of 149.6 million kilometres from the Sun, while Venus is (on average) 108 million kilometres from the Sun and Mars (on average) is 227 million kilometres from the Sun.
What are the temperatures of the five planets closest to the sun?
For the planets Mercury and Mars, their maximum and minimum temperatures are listed:* Mercury (minimum = -184 °C; maximum = 465 °C) * Venus (average = 449 °C)* Earth (average = 7.2 °C)* Mars (minimum = -123 °C; maximum = 36 °C)* Jupiter (average = -153 °C)
Which planet has the highest temperatures?
Venus has the highest surface temperature, even hotter than Mercury.
What planet has high temperatures due to the runway greenhouse affect?
It’s actually Venus.
What is the warmest planet out of Jupiter Venus Mercury Mars or Earth?
Mercury. When the Sun is at it's peak, surface temperatures can reach 700 F. (370 C.). Improvement: Venus has the highest temperatures.
Could you jump higher on Venus or on Mars?
Mars. Because if you weigh 105 pounds here on earth then you would weigh 39.5 pounds on Mars while on Venus you would weigh 95.2. The whole jump height is all about the amount of force in Newtons you put into it and how much you weigh. So net time you think "Could you jump higher on Venus or on Mars?" Just think about the weight you have and the amount of force you put into it.
What is Mars average temperatures?
Mar's average temperature is -80 degrees Fahrenheit
Which planet is like earth but has no water?
Neither Venus nor Mars have appreciable amounts of water. Venus is shrouded in dense, poisonous clouds at very high temperatures; Mars has very little atmosphere.
Why do you think that scientists discuss manned missions to mars but not to venus?
Scientists discuss manned missions to Mars because it would be much easier to send humans to Mars because the conditions on Mars are much less extreme than those on Venus. For example, surface temperatures on Mars range between -125ºC to 35ºC while those on Venus range between 450ºC to 475ºC.
The Mars the planet is the hottest?
No, Mars is very cold. Venus would be the "hottest" planet. --Constant hottest temperatures: Venus (Due to sulfuric acid causing greenhouse effect AKA intense global warming) --Hottest Temperatures: Mercury (due to proximity to sun)
What is Mars average low and high temperatures?
no clue & i asked first
Does Mars have lava?
Mars does not have lava, but probably has magma due to radioactive decay.
Venus mars and mercury in order of size?
The order of Mercury ,Venus and Mars by size is: Mercury ,Mars and Venus
