Is the Sky Falling?

Quck answer

The sky is not falling. This phrase is often used metaphorically to express a sense of panic or fear about a potential disaster. In reality, the sky is not actually falling and there is no imminent danger. It is important to approach alarming situations with a rational mindset and rely on factual information. While there may be challenges and problems in the world, it is crucial to stay calm, assess the situation objectively, and work towards finding solutions. Panicking or assuming the worst will not lead to productive outcomes.

If you regularly watch the news, you are aware that occasionally objects, such as meteors and satellites, descend from the sky towards Earth. Some individuals may be concerned and believe that the sky itself is falling. But is there anything to be alarmed about?

Surprisingly, space is filled with an almost infinite amount of things that could potentially fall to Earth one day. Some of these objects are extremely small, while others are quite large. Some are natural, while others are man-made.

For instance, orbital debris, also known as space junk, refers to man-made objects that orbit the Earth but are no longer operational. Space junk may include items such as old spacecraft, weather balloons, and broken satellites.

Scientists estimate that there are over 20,000 pieces of space junk that are at least four inches long. These pieces orbit the Earth at speeds of up to five miles per second. Space is also populated with rocks and stones known as meteoroids.

Occasionally, these objects will fall from orbit and enter Earth’s atmosphere. Fortunately, Earth’s atmosphere provides protection against the majority of these objects.

As the objects descend, they encounter air resistance from the atmosphere. This resistance generates friction, which in turn produces a significant amount of heat. In fact, most objects completely burn up before reaching the Earth’s surface.

For example, numerous meteoroids fall towards Earth every day. However, most of them burn up in the atmosphere. If a meteoroid is large enough to survive entry into Earth’s atmosphere, its hot and glowing surface may create a moving point of light in the sky as it falls. These are commonly referred to as meteors, “falling stars,” or “shooting stars.”

If a meteor successfully makes it through the Earth’s atmosphere and actually strikes the ground, it is then called a meteorite. Although many meteorites reach Earth each year, the probability of being hit by one is nearly zero. In recent history, only four individuals have been struck by a meteorite, and none of them were seriously injured.

The odds of being hit by space junk are about the same. Experts believe there is only one confirmed case of someone being hit by a piece of space junk.

In 1997, Lottie Williams from Tulsa, Oklahoma, was struck on the shoulder while walking in the park. Scientists believe she was hit by a fragment of the Delta II rocket. The piece of space junk weighed approximately the same as an empty soda can and felt like a tap on the shoulder.

So, the next time you hear about a meteoroid or old satellite falling towards Earth, there is no need to worry. Just remember that the sky is vast, the Earth’s surface is immense, and human beings are minuscule in comparison. Additionally, the majority of Earth’s surface is covered by the world’s oceans.

When an old satellite fell to Earth in late-September 2011, the chances of being hit by debris from the falling satellite were approximately 1 in 100 trillion. By comparison, the odds of being struck by lightning are about 1 in 60,000.

But what about catastrophic meteorite collisions? For instance, scientists believe that approximately 65 million years ago, a meteorite several miles wide struck Earth. This impact created the Chicxulub crater in the Gulf of Mexico and led to the extinction of the dinosaurs.

Catastrophic events like these are extremely uncommon. Experts estimate that they occur only once every 100 million years or so. So there is no need to worry, as there is a global community of scientists who diligently monitor the skies for any potential objects that may fall to Earth.

Give It a Try

Would you like to delve deeper into the world of meteoroids, meteors, and meteorites? Enlist the help of an adventurous friend or family member and try out one or more of the following activities:

  • Have you ever wondered what would happen if a meteorite were to strike Earth? Visit the Impact Earth! website to explore various disaster scenarios. You can select the size of the hypothetical meteorite or even choose from options like a school bus or the continent of Asia. You can also adjust other variables such as impact angle and velocity. Do any of these scenarios seem frightening? How do you think life would be affected if a meteorite as large as a school bus hit the continent you reside on?
  • Did you know that meteorites have collided with Earth numerous times in the past? Learn about famous craters from historical events. Gaining knowledge about these past occurrences can help you make predictions about future events. Have you ever had the chance to observe a real crater up close? Conduct an online search to see if there are any craters near your location that you could visit.
  • If you find yourself genuinely concerned about the possibility of the sky falling, take a moment to revisit the story of Chicken Little (also known as Henny Penny or Chicken Licken). You can read “The Remarkable Story of Chicken Little” online. And remember, when you encounter a “Chicken Little” who claims that the sky is falling, you can rely on your understanding of probabilities. If you’re up for a challenge, try creating your own story inspired by Chicken Little, incorporating real-life events and the knowledge you gained from today’s Wonder of the Day. Let your imagination run wild!
