First, think about you, one out of about 7.3 billion people on the planet. If you take America as an example, it has about 323 million people (and that number is growing, by a net gain of one person every 13 seconds). If that seems huge, look at humans' relative size in relation to this planet, the "Blue Marble" that we call Earth. According to The National Center for Health Statistics, the average U.S. man's height is 69.2 inches, or 5 feet 9.2 inches. The Earth's height is about 29,035 feet. Therefore, the approximate height of a U.S. man (about 6 feet) is only 1/5000, or one five thousandth, of the Earth's height of almost 30,000 feet.
Moving on, while the Earth may seem big now, it isn't as much so when you look at the size of our sun. Over 1 million Earth's could fit into it! The Sun dominates out solar system, the "neighborhood" in which we live. Ninety nine percent of our neighborhood is made up of our sun. So what is the other one percent, you ask? Well, it consists of all 8 planets, including Earth, as well as empty space, man-made space junk, dwarf planets, including Pluto and its moons, Charon, Nix, and Hydra, asteroids, the Oort Cloud, which contains premature comets and is at the edge of our solar system, our moon, and all other matter in our stellar "neighborhood." And our sun, a medium sized star, is one of at least 2 billion stars in our galaxy.
