The distance between the center of the Earth and the surface of the planet is 6,371 kilometers (3,958 miles), the crust is 35 kilometers (21 miles) thick, the mantle is 2855 kilometers (1774 miles) thick — and the deepest hole we have ever drilled is the Kola Superdeep Borehole, which is only 12 kilometers deep.

In general, the planet Earth is a large and complex globe. But, if one were to measure it from one end to the other, how big would it be? How many kilometers (and/or miles) would someone have to go if they just started walking and wanted to get back to where they started? The quick answer is that it is little more than 40,075 kilometers (or just over 24,901 miles ).
How close to the Earth’s core have we been?
Even now, the deepest hole we’ve ever dug into the Earth is around 12 kilometers deep, although the distance to the center of the Earth is more than 500 times greater, at 6,370 kilometers.
How long is 1 hour in space?
Answer: The product of that number multiplied by one hour is 0.0026 seconds. In this case, a person in that deep space location would have a clock that would operate for one hour, while that individual computed that our clock ran for 59 minutes and 59.9974 seconds.
How hot is the center of the Earth?
According to new research, scientists investigating what the conditions in the Earth’s core should be like discovered that the heart of the planet is far hotter than previously thought—approximately 1,800 degrees hotter, putting the temperature at an incredible 10,800 degrees Fahrenheit.
How hot is it 1 mile underground?
It would be quite hot below earth. The geothermal gradient shows that on Earth, 1 mile underground would be around 40-45 degrees Celsius (75-80 degrees Fahrenheit), precisely as you mentioned, hotter than the surface. Unless your subterranean metropolis is buried behind a layer of permafrost, that would be a significant obstacle to human existence.
Why can’t we drill to the center of the Earth?
Despite the fact that it is the thinnest of the three primary layers, mankind have never managed to drill all the way through it. Finally, the mantle accounts for an astounding 84 percent of the planet’s total volume. It would be necessary to drill through solid iron to reach the inner core. This would be particularly challenging due to the fact that there is almost little gravity at the core.
What would happen if you drilled a hole to the center of the Earth?
The gravitational attraction in the center of the earth is zero because there is an equal quantity of stuff in all directions, each exerting an equal gravitational pull on the rest of the planet. With such dense air surrounding you, you finally lose velocity and come to a complete halt in your yo-yo motion around the center of the earth. You wind up stranded at the core of the planet, unable to move.
How much do astronauts get paid?
Civilian astronauts are paid in pay grades ranging from GS-11 to GS-14, which are determined by their academic achievements and work experience. Currently, a GS-11 astronaut earns a starting pay of $64,724 per year, while a GS-14 astronaut can earn a salary of up to $141,715 per year [source: NASA].
Do you age slower in space?
We all have a distinct way of measuring our experiences in terms of space and time. Due to the fact that space-time is not flat, but instead is curved, and it can be twisted by matter and energy, this is true. And for astronauts aboard the International Space Station, this implies that they will age only a smidgeon slower than folks on the ground. Because of the consequences of time dilation, this is the case.
How cold is space?
The distance between gas and dust particles increases as we travel beyond our solar system and beyond the far reaches of our galaxy, into the immense nothingness of space. As a result, the capacity of gas and dust particles to transmit heat decreases. Temperatures in these arid regions can drop to as low as -455 degrees Fahrenheit in certain cases (2.7 kelvin).
How long can Earth last?
They predict that the overall habitable lifetime of the Earth – before it loses all of its surface water – is around 7.2 billion years, but they also estimate that an oxygen-rich atmosphere may only be available for approximately 20 percent to 30 percent of that period.
How hot is the moon?
The temperature of the moon’s surface may reach 260 degrees Fahrenheit when sunlight strikes it directly (127 degrees Celsius). When the sun sets, temperatures can drop to minus 280 degrees Fahrenheit (minus 173 C).
What’s hotter the sun or the center of Earth?
The Earth’s core is far hotter than the Sun’s outermost layer. Located in the Sun’s apparent outer atmosphere, known as the photosphere, are massive boiling convection cells that reach temperatures of 5,500°C. The temperature of the Earth’s core is around 6100 degrees Celsius. The inner core, which is under enormous pressure, is solid and may consist of a single massive iron crystal.
