which is the hottest planet and why?

Answer 1

Venus.

It is the second nearest planet to the sun and due to its atmosphere full of carbon dioxide and sulfuric acid, it has the ability to trap heat. So, basically, major global warming is taking place on Venus.

Although Mercury is nearer to the sun, its atmosphere is weak and contains sodium, potassium and oxygen. These, when exposed to the sun's rays, are lost/decomposed. Therefore, there is not much atmosphere left to trap the heat, leaving it cooler than Venus.

Answer 2

Tau Boötis Ab (τ Boo Ab / τ Boötis Ab) is an extrasolar planet orbiting Tau Boötis A. The designation is often written as Tau Boo b, but since Tau Boo B is a red dwarf companion of Tau Boo A, it is better to use the first mentioned designation. In 1999 the planet was dubbed the Millennium Planet.
Because τ Boo is hotter and larger than the Sun and the planet's orbit is so low, it is one of the hottest known planets, with a temperature about 1500 K. Although it has not been detected directly, it is certain that the planet is a gas giant.

As Tau Boötis Ab is more massive than most known "hot Jupiters", it was speculated that it was originally a brown dwarf, a failed star, which had lost most of its atmosphere in the heat of the star. However, this seems very unlikely. Still, such a process has actually been detected on the famous transiting planet HD 209458 b.

Answer 3

Venus. Mercury may be the CLOSEST to the sun, but it is NOT the hottest. Venus has vapors and clouds that trap heat and humidity thus making it by far the hottest planet. Mercury obviously comes in second, but venus is the hottest planet (even though it is second-closest to the sun).

Answer 4

hmm here venus is the hottest since i read all the commets i thouht mercury was the hottest so i made an mistake venus is surely the hottest cause of its atmosphere keeping in the heat from the sun....


Avg. Surface temp.: Day 623 K for mercury
Surface* temp. min* mean max
228 K 737 K 773 K

Answer 5

The hottest planet in our solar system is Venus. It's atmospheric conditions keep most of the radiation from the sun in.

Answer 6

the favorite planet interior the photograph voltaic device is Venus. One could desire to think of that Mercury being the closest to the sunlight could be the favorite, yet unfortunately it is no longer. besides the undeniable fact that Mercury could desire to get carry of the main photograph voltaic potential, maximum of it is radiated decrease back into area. Venus on the different hand, would not radiate any of the potential it gets decrease back into area by using it is greenhouse gases. by using this the outdoors temperature of Venus is approximately 460 ranges C while Mercury's optimum is a chilling 427 ranges C. $ observe: Mercury's temperature varies counting on it is rotation, while Venus would not. It continues to be warm sufficient to soften lead all 12 months long, no be counted the place you're. Fancy a trip?

Answer 7

Venus. The entire planet is covered by dense cloud layers that allow heat from the sun to reach the surface but not to radiate back into space. Typical surface temperatures are in the 900-degree range.

Answer 8

many of u have said its mercury and some venus
well the correct answer is Venus.

venus is the second planet from the sun but it is hotter than mercury.this is becoz the atmosphere around venus is mainly composed of carbon dioxide.the carbon dioxide produces Green House effect on the Venusian surface.thus the temperature on the Venusian surface remains very high.the earth's atmosphere contains a very small quantity of carbon dioxide.

Answer 9

mercury because it is the closest planet to the sun so the heat and light rays from the sun takes a shorter time to reach it thus it will receive the full heat from the sun unlike earth it is far away from the sun the heat rays cool don a bit before they reach the earth that is why we do not burn to death.

Answer 10

In our solar system, Venus. Noxious gases trapped by a cloudy atmosphere and just being close to the sun.

Surprisingly, not Mercury. No atmosphere to trap in heat.
