In terms of the solar system planetary ordering, Earth is the third planet closest to the Sun. As far as we know, Earth is the only place in the observable universe that hosts life as we know it. Earth's age is 4.5 billion years old....
"To obtain an idea of the size of a light-year, take the circumference of the Earth (24,900 miles), lay it out in a straight line, multiply the length of the line by 7.5 (the corresponding distance is one light-second), then place 31.6 million similar lines end to end," NASA's ...
NASA researchers have found that at 1 astronomical unit (AU), which is the distance from the sun to Earth, equal to 93 million miles (150 million km), sunlight can produce about 1.4 kilowatts (kw) of power. If you take 1.4 kw and divide it by the speed of light, you would find ...

Related: How old is Earth? What is Earth's radius, diameter, circumference and shape? Earth's widest point is the equator, which runs across the planet's center at zero degrees latitude. This is because Earth is not a perfect sphere; it has a prominence across its center called the equa...
Just 90 feet upslope from Mill Creek, a crack split open across the top of the pipeline, stretching nearly one-quarter of its circumference. The pressure in the pipeline at the time was well below what the Keystone is designed to handle, and we...
The earth is rotation relatively regular around the polaxis. During one day any point on the earth's surface runs on a circular orbit around the polaxis. So if you cut the earth along the equator through the center the cut's surface will be a circle. That means that the shape of the...
This incredibly accurate science experiment was centuries ahead of its timeAlex Kuzoian
If it was still functioning properly when that was completed, it would be boosted by Saturn’s gravity to visit Uranus and Neptune before also leaving the ecliptic and exiting the solar system. This was considered a long shot, but amazingly, everything worked as planned. Next, what kind of...
