which planet is hotter?

Answer 1

Most people think it's Mercury since it is closest to the sun. That is incorrect.

Venus is actually the hottest since it has an extremely thick atmosphere, which consists mainly of carbon dioxide and a small amount of nitrogen. The pressure at the planet's surface about 90 times that at Earth's surface—a pressure equivalent to that at a depth of 1 kilometer under Earth's oceans. The enormously CO2-rich atmosphere generates a strong greenhouse effect that raises the surface temperature to over 400 °C. This makes Venus' surface hotter than Mercury's, even though Venus is nearly twice as distant from the Sun and receives only 25% of the solar irradiance.

Answer 2

Venus is the hottest planet.

Venus' atmosphere is made up mostly of CO2. This creates an out-of-control greenhouse effect. The heat the planet absorbs from the sun is kept by the planet, making it hotter than a home oven cooking a turkey.

Mercury, though closer to the Sun, does not have an atmosphere. The planet then absorbs only a little energy from what it receives from the sun. So the day side of Mercury may be very hot (still not as hot as Venus), but the night side is very cold.

Answer 3

Venus

According to both ground-based and space-borne observations, the average surface temperatures of Venus are around 750 K. It does not seem likely, either at the poles or on the tops of the highest Venus mountains, that the surface temperature will be below 400 K, and noontime temperatures are probably significantly hotter than 700 K. Thus, quite apart from the other surface conditions, the temperatures on Venus seem too hot for terrestrial life. It is still not possible to exclude a Venus surface life with a rather different chemistry, although hydrogen bonding would be much less suitable for the geometrical configuration of polymers on Venus than it is on Earth.

Answer 4

While many people think it is Mercury because it is so close to the Sun, it is actually Venus. Thanks to its thick atmosphere and the "greenhouse" effect, the average surface temperature on Venus is over 400 C.

Interestingly, and to further solidify Venus's position, it maintains this surface temperature everywhere on the planet. Day vs night makes virtually no difference. In contrast, the surface temperature on the 'dark" side of Mercury is well below -200 C while the "sunny' side is over 200 C. Things must get pretty interesting at sunrise and sunset.

Answer 5

Mecury is the hottest planet followed by Venus then Earth, then Mars, then Jupiter ,then comes Saturn , then Uranus then follows Neptune and last but not the least Pluto which is the coldest planet and has the farthest distance from the sun.

Answer 6

Mercury

Answer 7

Mercury

Answer 8

hotter than what? are you asking which planet is hottest?
(in English the ending "-er" refers to the comparison between two objects; the ending "-est" refers to the comparison of more than two objects)

I will assume you mean hottest planet: that is Venus where the atmosphere traps the heat

Answer 9

Venus has the hottest surface temeratures. Its thick atmosphere has created a runaway greenhouse effect that has made it even hotter than Mercury, even though it is farther from the sun.

Answer 10
