Amazing Facts About Earth You DIDN’T KNOW!
10. 1.3 Million EarthsThink you know how big Earth is? If you guessed about 3,959 miles or 6,371 kilometers in radius,you’re right; but, relative to some of our outer space neighbors, what does that mean?Of the 9 commonly recognized planets, our home planet is 5th largest, only falling behindthe massive Jupiter, Saturn, Uranus and Neptune; but let’s look at El Sol for another comparison.It would take about 1.3 million Earths mushed together to recreate the size of the sun,which is approximately 108 times larger than Earth itself.
9. A Real Earth Day You may assume you’ve been spending yourlife enjoying full 24-hour days here on Earth, but you know what they say about assuming.In actuality, your days fall short of 24-hours, with a full rotation occurring within 23 hours,56 minutes and 4.1 seconds. If you think about it, our current method of daily cycling addsabout 1,460 minutes a year. So, who’s to blame for the additional time each day? The24-hour clock can be traced back to ancient Egypt, which divided the day into 10 hoursof day, 12 hours of night, with one hour added at twilight and one at the end of the day.
8. Distance from the Sun Being only the 3rd rock from the sun, onewould think Earth is pretty close to that giant, glowing, celestial orb… right? Well,we all haven’t melted to death, so we’re not really that close. In fact, at our closest,we’re a hefty 92.95 million miles or 149.6 million kilometers away from the sun. There’salso quite a bit of a leap from Earth to the next farthest planet of Mars, at its closest,is an additional 36 million miles or 57 million kilometers away.
7. Earth’s Lonely Satellite As you’ll come to find in our last stopson the express train to knowledge-town, Earth certainly doesn’t have the fewest satellites,but that doesn’t make our moon any less lonely, accompanied only by over 12,000 near-Earthobjects. Thought to be about 4.5 billion years old – not much younger than Earth itself- the Moon is approximately 238,855 miles or 384,499 kilometers away and is directlyresponsible for the tides on Earth. Though around 27% the size of Earth, the Moon isactually the 5th largest natural satellite in the solar system, only falling behind Jupiter’sGanymede, Callisto, and Io and Saturn’s Titan.
6. The Many Quakes of Earth We’re no strangers to hearing about quakesall over the globe. From the calmer trembling of the Earth’s crust to the far more devastatingquakes, as a whole we probably knowingly experience several dozen a year. According to the NationalEarthquake Information Center, what we’re feeling is just the tip of the iceberg – andthe United States Geological Survey thinks it’s even more drastic than the NEIC states.According to the NEIC, approximately 50 earthquakes a day are recorded, or around 18,000 a year.The USGS claims that there are several million each year, with so many going undetected eitherbecause they’re in remote areas or due to their very small magnitudes.
5. What’s Visible from Space? We have done a lot to this planet-sometimes creating beauty works, but often showing the worst people can dishout – but we know you’re wondering just how much of it is actually visible from space?Technically, thinking in the general definition of what we consider “space,” you won’tbe able to distinguish anything; but cross over into low-orbit Earth, and there are afew structures you can sneak a peek at, such as The Great Pyramids of Giza and the 64,000acres in southeastern Spain known as the Greenhouses of Almeria. Really, though, outside of beingable to identify cities, larger bridges here and there and lots of smog, you won’t beable to play much of a game of “I Spy.”
4. Giant Mushrooms of EarthPrior to the introduction of intelligent humanoid life, Earth was known for its “larger thanlife” inhabitants. Among the more sizable things that once lived on the Earth’s surfacewere what scientists believed to be giant mushrooms. Even more intriguing than the thoughtof Earth being coated with fungi up to 24 feet or 8 meters high is that these sporesactually towered over what we consider “normal” plant life. Fossils of Prototaxites date backto over 350 million years ago, during a time when, quite ironically, life on Earth wasstill pretty small scale. Though popular theory pegs these fossils as once being fungus, thereare still those unsure of the organism’s true lineage.
3. How Deep Does it Go? Holes have popped up all over the Earth’ssurface and some have even been at the behest of Russian scientific experiments – butthere’s one natural point that goes far beyond any known cave, valley, or canyon.The Mariana Trench, located in the western Pacific Ocean, just east of the Mariana Islands,reaches a depth of 36,070 feet or 10,994 meters below sea level. Expeditions in 1960 and 2012were the only successful attempts at reaching the bottom of the trench and, no, neitherfound the illusive megalodon. On land, the deepest point is an artificial hole startedin the 1970’s. After 19 years of attempts and drilling, the Kola Superdeep Boreholereached a depth of 40,230 feet or 12,262 meters.
2. Is Earth Really That Unique?Quite often we hear about how different Earth is when compared to other planets in the MilkyWay, but is Earth really all that unique? In reality, there have been discoveries ofother planets many, many light-years away of planets that are quite similar to our preciousblue sphere. In September of 2010, a planet known as Planet G, or Gliese 581g, in theGliese 581 system was located. Planet G is said to be able to support life, similar tothat found on Earth. Unfortunately, current technologies limit knowledge on just how similarto Earth Planet G really is, but the potential is there.
1. An Ungodly Naming As we’ve gone through the solar system,chances are you noticed the trend when it comes to their names. They’re pretty muchall named after a Roman or Grecian god. All of them, of course, except for Earth. Ourlittle planet’s moniker is believed to stem from the Indo-European “er”, with routesin the Germanic and Anglo-Saxon “erde” and “erda”, along with the proto-Germanicroot of “erpo”. In Germanic paganism, Earth was a goddess that paralleled the RomanTerra and Grecian Gaia, so while it may not have been directly named after a god or goddess,it still can be connected to one.
