A human body, or any object on the Earth, is never at rest. Even when you’re asleep in bed, you’re moving pretty fast. Our Milky Way Galaxy is rotating at 225 kilometers per second, and hurling through the cosmos at an estimated 305 kilometers per second. Add those figures together, and we’re racing through space at around 530 kilometers, or 330 miles per second. So in one minute’s time, you’ve traveled almost 20,000 kilometers, or more than 12,000 miles. And your friends always complain that you never go anywhere. |

An Asteroid Might Hit The Earth in 2029 The greatest chance so far, according to astronomers, of a large asteroid colliding with the earth and wiping life out is in 2029. Asteroids have hit the planet before, and caused mass extinctions, so there is some precedent for it happening again. The culprit this time is the Apophis Asteroid (99942 Apophis), which is headed our way in 2029. There’s a little less than a 3% chance that this bad boy will crash into terra firma. Let’s hope Apophis gives the planet a miss, otherwise you can stop paying into your retirement account right now. |

We Are Made Out of Stars Human beings are literally made out of star stuff . Almost all of the chemical elements that make up a person come from the stars. Any element heavier than hydrogen originated in the stars, and we are definitely composed of more than hydrogen. Calcium, carbon, hydrogen, nitrogen, oxygen and around 60 other basic ingredients make up a human being. Since hydrogen and helium were the only elements around before the stars “cooked” up some more, it’s a safe bet that most of the substance that constitutes the “physical” you comes from the stars. |

One Million Earths Could Fit Inside The Sun Even though there are a lot of stars out there, none is more important to us than our own sun. When compared to other stars, it’s fairly small, classified as a G2 dwarf star. But that doesn’t mean we’re complaining. Approximately one million Earths could fit inside this dwarf star. It might not be the largest star in the universe, but it gets the job done as far as sustaining life on Earth goes. |

The Biggest Mountain in Our Solar System Is on Mars Sorry Mount Everest — you’re not the king of the solar system. That honor belongs to Olympus Mons, a massive mountain on our planetary neighbor, Mars. Olympus Mons is a giant mound of red dirt and rock. This volcanic behemoth is 2,400 meters, or 80,000 feet tall, which makes it almost 15 miles high. Everest is a mere dwarf in comparison. This giant Martian volcano is either a mountain climber’s wildest dream, or worst nightmare.
