Which planet is hottest and why?

Which planet is hottest and why?

Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system’s hottest planet. The mean temperatures of planets in our solar system are: Mercury – 333°F (167°C) Venus – 867°F (464°C)

Why is Venus hotter than Mercury Class 8?

Hint: Venus is hotter than Mercury because it has a much thicker atmosphere. Mercury is closer to the Sun but it has a very thin atmosphere and all the heat trapped goes out in space, while Venus with its much thicker atmosphere holds all the heat it gets.

Is there any planet hotter than Venus?

Venus is not the hottest planet in the universe. The hottest known planet is KELT-9b, which has a surface temperature of 7,800 degrees Fahrenheit, or 4,300 degrees Celsius, according to NASA’s Jet Propulsion Laboratory at the California Institute of Technology. It is 670 light-years from Earth.

Why is Venus hotter than Mercury planet?

The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.

What are the 3 coldest planets?

Name of Planets (Hottest to Coldest)	Mean Temperature (Degree Celsius)
1. Venus	471°C
2. Mercury	(430°C) during the day, (-180°C) at night
3. Earth	16°C
4. Mars	-28°C

What is the 2nd coldest planet?

Neptune is the second coldest planet, Uranus’s atmosphere makes it the coldest planet with temperature of minus 224 deg. celcius.

Why is Venus the hottest planet short answer?

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

Why is Venus the hottest planet of Class 6?

The greenhouse effect increases the temperature of Venus making it the hottest planet in the solar system.

What is hottest place on Earth?

But with its “consistently hot footprint over a large area,” says Mildrexler, who was not involved in the present study, “the Lut Desert has really emerged as the hottest place on Earth.”

What is the hottest planet of all time?

It has a strong greenhouse effect, similar to the one we experience on Earth. Because of this, Venus is the hottest planet in the solar system. The surface of Venus is approximately 465°C!

Which planet is known as the Earth’s twin?

Thanks to Venus Express, Taylor now describes Venus as “Earth’s twin, but separated at birth.”

Which planet is coldest?

Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that.

Why is Venus the hottest planet for kids?

Even though Venus isn’t the closest planet to the Sun, it is still the hottest. It has a thick atmosphere full of the greenhouse gas carbon dioxide and clouds made of sulfuric acid. The gas traps heat and keeps Venus toasty warm.

What is the second hottest planet?

2. Mercury: The average temperature of Mercury is 167 degree Celsius. It is the first nearest planet from the Sun and the second hottest planet in the solar system.

What is the hottest thing in the universe?

A supernova is the hottest thing in the universe. The temperatures at the core during an explosion skyrocket up to 6000X the temperature of the sun’s core.

Who is the oldest planet?

Jupiter formed less than 3 million years after the birth of the solar system, making it the eldest planet. Saturn formed shortly after, amassing less material since Jupiter gobbled such a large portion of the outer disk.

When did Mars dry up?

Mars once ran red with rivers. The telltale tracks of past rivers, streams and lakes are visible today all over the planet. But about three billion years ago, they all dried up—and no one knows why.

Which is the brightest planet?

Venus, which can be seen with the unaided eye fromEarth, is the brightest planet in our Solar System. Venus was given the nickname evening star and morning star because of its bright, consistent presence.

Which is the hottest and coldest planet and why?

1. Venus: The average temperature of Venus is 464 degree Celsius. It is the hottest planet in the solar system and the second nearest from the Sun.

Why is Neptune hotter than Uranus?

Neptune wasn’t hit by a huge asteroid like Uranus was, so it has been able to hold on to more of its heat. You might also be surprised to learn that the closest planet to the Sun, Mercury, can also be extremely cold.

Why is Mars hotter than Mercury?

Mars is reddish color and some people might have guessed that Mars is the hottest planet in the solar system. But just because it’s red, doesn’t make it the hottest. Mercury is the planet that is closest to the sun and therefore gets more direct heat, but even it isn’t the hottest.

Which planet is the coldest and why?

The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and ‘only’ about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
