## What is the original temperature of the Sun?

The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius).

## What is the atmospheric temperature of the Sun?

How can the temperature of the Sun’s atmosphere be as high as 1 million degrees Celsius when its surface temperature is only around 6000°C? By simulating the evolution of part of the Sun’s interior and exterior, researchers have identified the mechanisms that provide sufficient energy to heat the solar atmosphere.

How do you calculate the surface temperature of the Sun?

Temperature on the surface of the sun calculated with the Stefan-Boltzmann-rule

1. σ=5.67∗10−8Wm2K4 (Stefan-Boltzmann constant)
2. D=1.496∗1011m (Earth-Sun average distance)
3. R=6.963∗108m (radius of the Sun)
4. (Wikipedia gives 5777K because the radius was rounded to 6.96∗108m)

How hot is Betelgeuse?

3,500 K
Betelgeuse/Surface temperature

### Is lightning hotter than the Sun?

Air is a very poor conductor of electricity and gets extremely hot when lightning passes through it. In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).

### How do you calculate surface temperature?

2) surface heat flux equation: H = r. c (Ts – T) / r, where r is the density of air, c its specific heat, and r is the diffusion resistance between the surface and the air.

Is Betelgeuse hotter than Sun?

Betelgeuse is actually cooler than our sun. The sun’s surface temperature is about 5,800° Kelvin (about 10,000° Fahrenheit), and Betelgeuse is roughly half that, about 3,000° Kelvin (about 5,000° Fahrenheit). That is why it is red — red stars are cooler than the sun, blue-white stars are hotter.

What star is hotter than Polaris?

Polaris has a hotter surface temperature than Antares with more than twice the temperature. Antares, a red supergiant, has a surface temperature of…

#### What’s the hottest thing in the universe?

The hottest thing in the Universe: Supernova The temperatures at the core during the explosion soar up to 100 billion degrees Celsius, 6000 times the temperature of the Sun’s core.

#### Can you touch a person struck by lightning?

Lightning victims are NOT electrified and you will NOT be electrocuted by touching someone who has been struck in a lightning storm. It is safe to touch a lightning victim and administer first aid immediately.

Is the Sun’s corona hotter than core?

Estimating the photosphere’s heat has always been relatively straightforward. Edlén and Grotrian’s finding that the sun’s corona is so much hotter than the photosphere – despite being further from the sun’s core, its ultimate source of energy – has led to much head-scratching in the scientific community.
