I Had No 'Earthly' Idea

1. Along with orbiting around the Sun at 66,600 mph, the Earth is also rotating at its axis at about 1,070 miles per hour.  So you are simultaneously hurtling around the Sun at 66,600 mph while sitting on a rock that is spinning at 1,070 mph. On top of that, our whole solar system is rocketing through space around the center of the Milky Way at around 559,234 mph.  On top of that, our galaxy is hurtling through space at around 671,080 mph, with respect to our local group of galaxies.  On top of that, for all we know, our entire Universe is hurtling through some unknown medium at some other ridiculous speed.

2. The energy required to stop the Earth orbiting the Sun is about 2.6478 × 1033 joules or 7.3551 × 1029 watt hours or 6.3285*1017 megatons of TNT.  For reference, the largest nuclear explosion ever detonated (the Tsar Bomba by the Soviet Union) "only" produced 50 megatons of TNT worth of energy.  So it would take about 12,657,000,000,000,000 of those nuclear bombs detonated at the correct location to stop the Earth from orbiting the Sun.

3. The Earth isn't perfectly spherical in shape.  The combination of gravitational and centrifugal forces, along with the tilted axis of the Earth have resulted in a bulge of mass around the equator. Therefore the Earth's shape is classified as an oblate spheroid or ellipsoid. The polar diameter of the Earth is about 26.7 miles (43 km) shorter than its equatorial diameter causing a difference of about 0.3%. This very slightly oblate shape affects the weight of an object according to its position on the Earth's surface. For example: A 20-lb bag of sand would weigh less at the equator than at the North Pole. This is because the further an object gets from the center of the Earth, the less it weighs. If the Earth were a perfect sphere, then objects would weigh exactly the same  anywhere on Earth.

4. The Earth is hottest when it is furthest from the Sun on its orbit, not when it is closest. During the period when the Earth is furthest from the Sun (aphelion- in July when the Earth is at around 94.8 million miles/ 152.6 million kilometers away from the Sun), the average temperature of the entire planet is about 4°F (2.3°C) higher than when it is closest to the Sun (perihelion- in January when we are at about 91.1 million miles /146.6 million kilometers away  from the Sun). On average, the intensity of sunlight falling on Earth during aphelion is about 7% less than during perihelion. Despite this, the Earth ends up being warmer during the period in which it is furthest away from the Sun. As you might have guessed then or already known, the seasons are not caused by the distance the Earth is from the Sun, but rather are caused completely by the fact that the Earth is tilted on its axis 23.5°. This is why when it's summer in the Northern Hemisphere, it's winter in the Southern Hemisphere, and vice-verse.

5. The average temperature of the Earth year round is around 61°F (16.1°C). The average coldest temperature on the Earth, in Antarctica, is around -60°F or -51.1°C and the average of the hottest part of the Earth, in the Sahara Desert, is around 130°F (54.4°C). That said, the hottest temperature ever recorded on Earth was 136°F (57.77 °C) in El Azizia, Libya on the edge of the Sahara Desert. The second hottest, 134°F (56.6°C), was recorded in Death Valley, California in the Mojave Desert way back in 1913. Whereas, the coldest temperature on the Earth was recorded at Vostok, Antarctica on July 31, 1983 at -128.6°F (-89.22°C).

6. Light travels from the Sun to the Earth in about 8 minutes and 19 seconds. While it only takes 8 minutes and 19 seconds for the light from the surface of the Sun to reach us, it actually takes about 10,000-170,000 years for a photon to travel from the core of the Sun to the surface.

7. The Earth's solid iron core, is surrounded by a fluid ocean of hot, liquid metal, that creates electric currents and consequently generates a magnetic field.  The magnetic North Pole,  first located in the early 19th century, has moved more than 600 miles (1,100 kilometers) northward since then. In the early 20th century it was estimated to have been migrating at about 10 miles (16 km) per year and is said to be moving even faster now at about 40 miles (64 km) per year in a northward direction.

8. About 800,000 years ago if you were to have stood facing what we call North now (by compass), you would actually have been facing South. The widely believed hypothesis states that there was once a pattern of 200,000 to 300,000 years when the polarity of the Earth's magnetic field reversed. During this long process, the magnetic poles slowly start migrating away from the axis around which our planet spins, and eventually get flipped around reversing the poles. Although this reversal is speculated to have occurred a number of times in the history of the Earth (about every 300,000 years), it has been over twice that long since the last one, leading many to speculate we're due for one sometime within the next couple thousand years or so.  A reversal today may have dire consequences for life on the surface of the planet as some theorize that the magnetic field will decrease to almost nothing for a time during the interim of the switch.  If this happens, ionizing radiation from the Sun will become a major problem for humans and many other life forms.  That being said, other scientists think this isn't likely and that the magnetic field will simply become "more complicated" during a switch with "magnetic lines of force near Earth's surface [becoming] twisted and tangled, and magnetic poles [popping] up in unaccustomed places. A south magnetic pole might emerge over Africa, for instance, or a north pole over Tahiti. Weird. But it's still a planetary magnetic field, and it still protects us from space radiation and solar storms."  This idea is backed by the fact that the magnetic switches throughout Earth's history don't seem to have every correlated with mass extinction of animal life on the surface of the planet.

9.   As alluded to, gravity on the Earth is not uniform. In March 2002, the GRACE (Gravity Recovery and Climate Experiment) mission was launched by NASA to accurately map variations in the Earth's gravity field. The mission involved two identical spacecrafts that flew about 220 kilometers apart in a polar orbit 500 kilometers above the Earth. According to NASA, the studies of this mission showed gravitational differences "due to surface and deep currents in the ocean; runoff and ground water storage on land masses; exchanges between ice sheets or glaciers and the oceans; and variations of mass within the Earth. "

10. According to a paper published in the journal 'Nature', scientists theorized that at one point the Earth may have had two close orbiting Moons. Outlined in the research paper, they explain just as the Moon was created some 4.5 billion years ago most likely from debris accreted, when a Mar's-sized object collided into Earth, a smaller sister moon made of the same rocky debris was also formed. This smaller moon was believed to have eventually had a slow-moving collision with the bigger Moon. The slow speed collision could have been forceful enough to plaster debris from the companion moon to the larger moon, rather than a fast collision that would have caused a crater or displayed signs of melting rock from the impact.

Famous Person Who Never Existed

Aunt Jemima



Currently owned by the Quaker Oats Company of Chicago, Aunt Jemima's trademark dates back to 1893, but was first registered in April 1937. She originated from the "Minstrel Show" as one of their stereotypical African-American characters. She was later adopted by commercial interests to represent the Aunt Jemima brand. The Aunt Jemima character received the Key to the City of Albion, Michigan on January 25, 1964. An actress portraying Jemima visited Albion many times for fundraisers. Soon after Quaker Oats introduced Aunt Jemima syrup in 1966. This was followed by Aunt Jemima Butter Lite syrup in 1985, and Butter Rich syrup in 1991. She has simply become just a logo for a brand name over the years. I always see her while I walk down the breakfast section of my local grocery store. She has an unforgettable smile and friendly look, it's perfect if you wanted to sell something!
