How hot is a nuclear bomb compared to the sun?

Temperatures of a nuclear explosion reach those in the interior of the sun, about 100,000,000° Celsius, and produce a brilliant fireball. The fireball shortly after detonation.

Are nuclear bombs as hot as the sun?

In a hydrogen bomb explosion, nuclear fission compresses an internal pellet, which then undergoes nuclear fusion in a runaway, energy-releasing reaction. For some brief moments, the temperatures in there can exceed those in the center of the Sun.

How hot are nuclear bomb?

The initial fireball.

Within a few tenths of millionths of a second after detonation, the center of the warhead would reach a temperature of roughly 200 million degrees Fahrenheit (about 100 million degrees Celsius), or about four to five times the temperature at the center of the sun.

How many nuclear bombs is the sun equivalent to?

In just 100 to 1,000 seconds, the disturbance can release an energy of 10²⁴ Joule. A single flare then creates an explosion equivalent to 2.5 million nuclear bombs on Earth, each with a destructive force of 100 Megatons of trinitrotoluene, or TNT.

How hot was the bomb on Hiroshima?

About 0.2 seconds after the detonation over Hiroshima, the fireball created reached a surface temperature of 7,700 degrees Celsius. From 0.2 to 3 seconds after detonation, the intense heat emitted from the fireball exerted powerful effects on the ground.

Sun VS. Atomic Bomb

What happens if you launch a nuke into the sun?

It's safe to say the nuclear bomb will have no effect at all. But actually it's even harder than that to perturb the sun. The nuclear bomb would be vaporised long before it reached the surface. It could be detonated in space somewhere near the sun.

Can you survive a nuclear bomb in a fridge?

Lucas said that if the refrigerator were lead-lined, and if Indy didn't break his neck when the fridge crashed to earth, and if he were able to get the door open, he could, in fact, survive. “The odds of surviving that refrigerator — from a lot of scientists — are about 50-50,” Lucas said.

Is Hiroshima still radioactive?

Is there still radiation in Hiroshima and Nagasaki? The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.

Is it possible to survive a nuke?

Technically, humans can withstand that much pressure, but most people would be killed by falling buildings. If you somehow survive all of that, there's still the radiation poisoning to deal with – and the nuclear fallout.

Is there anything hotter than sun?

And the answer: lightning. According to NASA, lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees. Meanwhile, magma can reach temperatures near 2,100 degrees.

Is lava hotter than the sun?

Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.

What is hotter than the sun's core?

However, outside the photosphere there is the Sun's corona, which can reach temperatures as high as 17,000,000 K; this is hotter than the center of the Sun, and is the hottest place in the solar system!

Can you survive a nuke in a pool?

While the radiation from the initial detonation is setting everything nearby on fire, the surface of the water will harmlessly evaporate. Since the boiling point of water isn't very high and the flash doesn't last very long, the whole body of water will stay cool, even if it's only a swimming pool.

Which animal can survive a nuclear disaster?

As it turns out, cockroaches can withstand a huge amount of radiation – which is why many survived the 1945 blasts.

How many miles away from a nuke is safe?

Those closest to the bomb would face death, while anyone up to 5 miles away could suffer third-degree burns. People up to 53 miles away could experience temporary blindness. But a longer-term threat would come in the minutes and hours after that explosion.

Is Chernobyl still burning?

Chernobyl reactor 4 is no longer burning. The reactor was originally covered after the disaster, but it resulted in a leak of nuclear waste and needed to be replaced. The systems for a new cover for the reactor were being tested in 2020 and is sometimes referred to as a "sarcophagus."

How long would it take for the Earth to recover from nuclear war?

Recovery would probably take about 3-10 years, but the Academy's study notes that long term global changes cannot be completely ruled out. The reduced ozone concentrations would have a number of consequences outside the areas in which the detonations occurred.

How long until Chernobyl is habitable?

How Long Will It Take For Ground Radiation To Break Down? On average, the response to when Chernobyl and, by extension, Pripyat, will be habitable again is about 20,000 years.

Can a submarine survive a nuclear bomb?

Most current submarines can survive at a depth of 400 m, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves. Submarines are also designed to withstand short pressure spikes from close explosions of deep charges and even nuclear explosions.

What cities are most likely to be nuked?

Redlener identified six cities that have the greatest likelihood of being attacked: New York, Chicago, Washington D.C., Los Angeles, San Francisco, and Houston. Only New York, Washington D.C., and Los Angeles' emergency management websites give ways to respond to a radioactive disaster.

How many nukes would it take to destroy the US?

The absolute doomsday scenario is a “nuclear winter.” For that to happen, the US and Russia would have to use about 2,000 nukes each and destroy major cities and targets, Toon told me.

What would happen if a nuke went off in Yellowstone?

So in conclusion, nothing would happen and Yellowstone would not erupt if for some reason a nuclear bomb was detonated near the supervolcano.

How many nukes would it take to destroy the moon?

Plenty of folks have done some thinking about how to explode the moon. Here's a piece from Gizmodo figuring that you'd need 9,000 bombs of the 15,000 kiloton "Castle Bravo" class to obliterate the entire surface of the moon.

Can you hide from a nuke?

Stay away from the outer walls and roof. Try to maintain a distance of at least six feet between yourself and people who are not part of your household. If possible, wear a mask if you're sheltering with people who are not a part of your household.
