# What is at the center of the sun?

## What is at the center of the sun?

The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur. Moving outward, next comes the radiative (or radiation) zone. Its name is derived from the way energy is carried outward through this layer, carried by photons as thermal radiation.

## What is the heat of the sun’s core?

Core: the temperature at the very center of the Sun is about 27 million degrees Farenheit (F).

How hot is the Earth 1 mile down?

The temp gradient is about 1.6 deg per 100 ft. Thus at 1 mile deep it is about 84 deg plus 60 deg or about 144 deg.

### How deep can humans go underground?

Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.

### What is the deepest a person has been underground?

This is the Kola Superdeep Borehole, the deepest manmade hole on Earth and deepest artificial point on Earth. The 40,230ft-deep (12.2km) construction is so deep that locals swear you can hear the screams of souls tortured in hell.

Which country has the deepest man made hole?

Russia

## What happens if you dig too deep in the earth?

To make things more difficult, as they drill deeper into the Earth, they’ll encounter extreme temperatures, possibly in excess of 1,000 degrees Fahrenheit (538 degrees Celsius), and fantastic amounts of pressure — as much as 4 million pounds per square foot in the vicinity of the mantle.

## How deep can you dig with a shovel?

10-15 feet

Why can’t we drill to the center of the Earth?

It’s the thinnest of three main layers, yet humans have never drilled all the way through it. Then, the mantle makes up a whopping 84% of the planet’s volume. At the inner core, you’d have to drill through solid iron. This would be especially difficult because there’s near-zero gravity at the core.

### Is it possible to dig a hole through the earth?

The furthest humans have ever gotten is the tip of the Kola Superdeep Borehole in northwestern Russia, which reaches a mere 7.5 miles beneath the ground. Even so, it took almost 25 years and ended when temperatures of over 350 degrees Fahrenheit made drilling impossible.

### Can you really dig a hole to China?

Take a closer look at a globe: China is actually not antipodal to the United States. That would be impossible, since they’re both in the Northern Hemisphere. If you dug a hole from anywhere in the lower 48 states straight through the center of the Earth, you’d actually come out… in the middle of the Indian Ocean.

What would happen if you drilled through the earth all the way to the other side and then jumped into the hole?

A tunnel, dug from one side of the Earth to the other would be, on average, 12,742 km. So it’s a shorter trip, sure, but that’s not the best part. If you jumped into the tunnel, you’d fall down towards the center of the Earth, accelerating constantly, thanks to gravity.

## How long would it take to dig to the earth’s core?

about 42 minutes and 12 seconds

## How do we know the earth has a core?

There are no samples of Earth’s core available for direct measurement, as there are for Earth’s mantle. Information about Earth’s core mostly comes from analysis of seismic waves and Earth’s magnetic field. The inner core is believed to be composed of an iron–nickel alloy with some other elements.
