what is the hottest planet?

Answer 1

The hottest planet in our solar system is Venus. It reaches 860 degrees (F), while Mercury only reaches 700 degrees (F).
http://en.wikipedia.org/wiki/Venus#Atmosphere
http://en.wikipedia.org/wiki/Mercury_%28planet%29

This is due to the "greenhouse" effect, which occurs on Venus, but not on Mercury.

The hottest planet in the universe, as far as we know, is called HD 189733b, and is known as a "hot Jupiter." It reaches 1700 degrees (F).

Jupiter and gas giant planets like Jupiter can become extraordinarily hot. Our Jupiter doesn't, it's much further from the sun than the "hot Jupiters." For more, see the following link or read the excerpt below:

The observations reveal that temperatures on this balmy world are fairly even, ranging from 650 degrees Celsius (1,200 Fahrenheit) on the dark side to 930 degrees Celsius (1,700 Fahrenheit) on the sunlit side. HD 189733b, and all other hot Jupiters, are believed to be tidally locked like our moon, so one side of the planet always faces the star. Since the planet's overall temperature variation is mild, scientists believe winds must be spreading the heat from its permanently sunlit side around to its dark side. Such winds might rage across the surface at up to 9600 kilometers per hour (6,000 miles per hour). The jet streams on Earth travel at 322 kilometers per hour (200 miles per hour).

"These hot Jupiter exoplanets are blasted by 20,000 times more energy per second than Jupiter," said co-author David Charbonneau, also of the Harvard-Smithsonian Center for Astrophysics. "Now we can see how these planets deal with all that energy."

Answer 2

What Is The Hottest Planet

Answer 3

As everyone who answered correctly knows, the hottest planet is Venus. Venus is basically a pressure cooker. Its atmosphere causes a runaway greenhouse affect letting lots of solar energy in, but not letting much back out again. Mercury might be closer to the sun, but since it lacks any atmosphere it has no way to trap the heat it picks up. Because of this, the night side of Mercury is pretty darn cold.

Answer 4

The hottest planet is Venus.

Mercury is the closest planet to the sun and reaches temperatures hotter than Venus, but only the 'daylight' side of Mercury is hot, the 'night' side of Mercury is actually very cold because there is no atmosphere on Mercury to hold any of the heat.

Venus does not reach the high temperatures that Mercury reaches, but the entire planet is extremely hot due to a dense Carbon Dioxide and Methane atmosphere that traps heat and keeps the entire planet hot enough to lead.

Answer 5

Venus is the hottest planet

Answer 6

the main well liked planet interior the image voltaic equipment is Venus. One ought to think of that Mercury being the closest to the solar may be the main well liked, yet lamentably it is not. regardless of if Mercury ought to get carry of the main image voltaic capacity, maximum of that's radiated lower back into area. Venus on the different hand, does not radiate any of the capacity it gets lower back into area by way of it is greenhouse gases. because of this the exterior temperature of Venus is approximately 460 stages C while Mercury's optimum is a chilling 427 stages C. $ be conscious: Mercury's temperature varies finding on it is rotation, while Venus does not. It continues to be warm sufficient to soften lead all twelve months long, no count the place you're. Fancy a trip?

Answer 7

In our solar system Venus is the planet with the hottest surface temperature, because it has a very thick atmosphere that traps heat in. Mercury is closer to the sun, but has virtually no atmosphere so it doesn't get as hot as Venus in daytime, and at nighttime its actually freezing cold.

Answer 8

You would think Mercury because it is the closest to the Sun, but you would be mistaken the hottest planet is Venus because of its atmosphere causes an extreme greenhouse effect.

F.Y.I. Scientists on this planet studied Venus atmosphere originally to see how the greenhouse effect would affect our planet.

Answer 9

With all its white-hot stars - Jessica Alba, Jeremy Piven, and Angelina Jolie, Alyssa Milano, Vin Diesel, and many many more - there is none hotter than Earth.

Ohh... temp-hot?

Temperature-wise, Venus ranks highest. Despite being second to Mercury in proximity to the Sun, its surface temperature is second to none. Its massive atmosphere creates a massive greenhouse effect, trapping enough heat to make it the hottest planet known to Man.

(Hotter than Earth)

Answer 10

The Sun is not a planet, it is a star. the others are correct, Mercury is the most hot, followed by Venus and then the Earth. In the course of the Suns lifetime, billions of years, all three will eventually be melted by the Sun as it grows in size over time.

Some might agree that the average, overall temp on the entire planet will go to Venus, but the absolute hottest planet, as far as highest possible surface temperature, is still Mercury.

OK people, enough. Venus IS the overall hottest planet, but the maximum high, on the equator of Mercury after long exposure to solar radiation is more hot than any point on Venus.
