Earth Was Created in a Wonderful Location
Our Sun Is Perfectly Located Within Our Galaxy
The spiral-shaped galaxy in which the earth is located is called the Milky Way. The spiraling arms and center of this galaxy contain many stars set close together, giving off its characteristic brightness.
Some stars explode into supernovas, causing deadly radiation to flow through nearby stars and planets.
The center and arms of galaxies are flooded with high amounts of radiation. Most stars are located in places with too much harmful energy for life.
Our solar system is located about two-thirds of the way out toward the edge of the Milky Way, where we are least likely to suffer collisions with other stars. Most of the stars in our galaxy are in the larger spiral arms or in the center. Because there are few stars near us, there is a low amount of radiation surrounding our solar system and we can observe the rest of the universe and our own galaxy much better.
Our Planet is Perfectly Located Within Our Solar System
Our solar system also contains thousands of asteroids and meteoroids. These sometime collide with planets. Jupiter keeps large rocks from hitting earth by attracting them with its strong gravity.
The earth's huge moon also protects us from many of rocks that cross our planet's path. The craters across the moon's surface demonstrate the frequency something has collided with the moon instead of earth. The moon's South Pole—Aitken basin—is the largest known crater in our solar system. It is eight miles deep and 1500 miles across. The earth's moon is unusually large.
In addition, our huge moon is a stabilizing anchor for our planet. Our moon prevents our planet from tilting too far from the attraction of the sun or Jupiter.
We are protected because of the way our solar system was created.
