This Is Why Objects Burn When They Re-Enter The Atmosphere – Forbes
17 nov. 2016Objects that enter Earth’s atmosphere burn not because they are falling from great height, but because they are traveling through the atmosphere at great speed. A returning spacecraft enters…

Why do things burn up on entering Earth’s atmosphere? Answer Dave – The main reason why things heat up when they hit the Earth’s atmosphere is they’ve got huge amounts of kinetic energy – they’re going incredibly fast.

Why Do Things Burn Up In The Atmosphere? [All You Need To Know]
As a gas compresses, its temperature rises. The collision with the gas molecules also converts some of the object’s energy of motion, also known as kinetic energy, into heat. This causes objects to heat up to temperatures as high as 3000 degrees Fahrenheit (1650 degrees Celsius)! Crazy, right!

Why do objects burn when they enter earth’s atmosphere?
For larger objects it’s more likely the pressure they create. In both cases the reason is the enormous speed, often tens of kilometers per second. When a larger object enters the atmosphere at these speed the air in front of it gets compressed so much that it becomes extremely hot. (Think of pumping up a tire; you’re also compressing air and …

Ask an Explainer Q: Why do things burn up when they enter Earth’s atmosphere? A: Rub your hands together. Do you feel them heating up? This is called friction, which is caused when two things rub together. Now imagine what would happen if your hands could move 25,700 kilometers per hour (16,000 mph). That’s how fast re-entry speeds are.

Atmospheric entry – Wikipedia
These forces can cause loss of mass ( ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Reentry has been achieved with speeds ranging from 7.8 km/s for low Earth orbit to around 12.5 km/s for the Stardust probe. [1]

Facts on Reentry into the Earth’s Atmosphere | Sciencing
Uncontrolled Re-entries. In 2012, roughly 3,000 objects weighing 500 kilograms (1,100 pounds) were in orbit around the Earth, and all will eventually re-enter the atmosphere. Because they aren’t designed for re-entry, they break up at an altitude of 70 to 80 kilometers (45 to 50 miles), and all but 10 percent to 40 percent of the pieces .

Layers of Earth’s Atmosphere | Center for Science Education
Earth’s atmosphere is composed of a series of layers, each with its own specific traits. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The exosphere gradually fades away into the realm of interplanetary space. The layers of the : troposphere … lesoutrali bot
