Which planet is the hottest?

Answer 1

Venus is correct. Venus is what will happen to Earth when the greenhouse effect (a byproduct of global warming) really kicks in.

Answer 2

Most people tend to think that Mercury is the hottest, but in reality, it's Venus. Mercury is the closest planet to the Sun, but Venus is completely covered with carbon dioxide clouds which causes the "greenhouse effect," keeping the planet the hottest in our solar system.

MERCURY: The temperature on the Sun-facing side is as high as 430°C. The planet rotates once every 58·6 Earth days, so its entire surface sees the Sun as a result.

VENUS: This dense atmosphere produces a run-away greenhouse effect that raises Venus' surface temperature by about 400 degrees Farenheit to over 740 K (hot enough to melt lead). Venus' surface is actually hotter than Mercury's despite being nearly twice as far from the Sun.

Answer 3

While Mercury is closest to the sun, Venus has the hottest surface temperature in the solar system. Why? Venus has a thick atmosphere composed mostly of carbon dioxide, which is a greenhouse gas, and this keeps the sun's rays that hit the surface from radiating back into space. Venus' thick planet wide cloud cover also contributes to this.
Mercury's rotational period (day) is about as long as it's year (amount of time it takes to revolve around the sun). This, along with the lack of a thick atmosphere, keeps one side of the planet scorchingly hot, while the nighttime side is extremely cold!

Answer 4

Venus has a carbon dioxide atmosphere 90 times thicker than that of the Earth, causing an efficient greenhouse effect by which the Venusian atmosphere is heated. The resulting surface temperature is the hottest of any planet—about 477° C (890° F).

Venus
Venus is the brightest object in our sky, after the sun and moon. Swirling clouds of sulphuric acid obscure Venus’s surface and inhibited study of the planet from earth until technology permitted space vehicles, outfitted with probes, to visit it. The probes determined that Venus is the hottest of the planets, with a surface temperature of about 462° C (864° F). Scientists believe a greenhouse effect causes the extreme temperature, the planet’s thick clouds and dense atmosphere trapping energy from the sun.,

Answer 5

VENUS is the HOTTEST planet of our solar system!! Here's WHY?

Mercury is closest to the sun, this is true. However, because of its proximity to the sun it lacks an atmosphere. Mercury's gaseous molecules reached escape velocity long ago and the atmosphere was 'burned off' leaving a vacant wasteland of rock with a similar surface to the earth's moon. There is nothing to hold in solar radiation, thus is flies out into space.

Venus Venus is a different story. Its atmosphere is primarily composed of carbon dioxide - the primary green house gas -, which acts like a one-way door. The solar heat enters, but it cannot leave. Thus, an oven is created. This is why Venus has no water. Pictures suggest that Venus once had an aqueous environment, but because of climatic changes and intense heat.... it evaporated.

Also, because of an overactive core, Venus seems to recreate its continents every X years. So, we do not expect to find fossils or many bacteria.

Answer 6

Venus is much drier than Earth and its atmosphere is 90 times as dense. It is the hottest planet, with surface temperatures over 400 °C, most likely due to the amount of greenhouse gases in the atmosphere.Although no definitive evidence of current geological activity has yet been detected on Venus, its substantial atmosphere and lack of a magnetic field to protect it from depletion by the solar wind suggest that it must be regularly replenished by volcanic eruptions.

Answer 7

The planet Mercury is the hottest as it is the nearest to the sun.
Venus is next.Pluto was the coldest but now it is not a planet anymore.Scientists used to think that Mars was hot and that Venus was cold.They discovered that this was wrong when spaceships landed on these planets.Well, if you're planning to
land there, I'll tell you just one thing.You'll be melting before you know it!!!!!!!

Answer 8

I think the hottest planet is mercury because it's the closest planet from the sun.

Answer 9

Mercury being the closest planet in our solar system to the sun would be the hottest

Answer 10

it is not mercury. Even though it is closest to the sun it is dead - no atmospere etc. Venus is hotter at the surface as is has a thick atmosphere which keeps the heat in and allows it to reach a higher temperature than that of mercury. Venus has an average temperature of around 500*C, mercury only around 100*C.

Answer 11

In our solar system, mercury is the hottest planet as it is closest to the sun.
