How Big is the Earth?
Earth is the third in distance from the sun and the fifth largest of the planets in diameter. The earth is not a perfect sphere but is slightly flattened at the poles. The diameter of the earth measured around the North Pole and the South Pole is about 42 km (26 mi) less than the diameter of the earth measured at the equator. The circumference of the Earth at the Equator is 24,902.4 miles or 40.076.5 km. The diameter which is the distance across the center at the equator (equatorial diameter) is 7926.42 miles or 12,756.34 km. The Polar diameter (measurement between the poles) is 7899.83 miles or 12,713.54 km. Total surface area is 510,100,000 sq. km (196,950,000 sq. miles) Volume is 1,083,230,000,000 cubic km (259,880,00,00 cubic miles) Average density is (water=1) 5.
The Size of The Earth Look at this picture of the Earth and some of its neighbors. Compared to these worlds, the Earth still looks very large. It is much larger for example than Pluto and Mercury, a few times larger than the planet Mars, and just slightly larger than the planet Venus. .menuItem { font-family: verdana; font-size: 10pt; color: #990000; text-decoration: none; } Earth’s Size Compared To Larger Planets As we compare the Earth with its larger neighbors however, we begin to see just how small it really is. The massive gas giant planets of our Solar System are many times larger than the tiny world that we inhabit. Notice the storm that is raging in the clouds on Jupiter. This storm is actually larger than our entire planet.
– Part III Earth’s Size Compared To Massive Stars Now, lets look at some objects that are so unbelievably large, that if they replaced our Sun in our Solar System, they would extend out, beyond the orbits of many of the planets. These super-sized stars are billions of times larger than our home planet, and millions of times larger than our Sun. .menuItem { font-family: verdana; font-size: 10pt; color: #990000; text-decoration: none; } As you go about your daily life, travel to school, to baseball or dance practice, ride your bike to the park, and look up at the clouds, remember that while Earth seems like a very big place, in reality it is just a tiny rock, a spec in the universe, so small that it cannot be seen unless you are very close to it. Geography and Geology are the studies of this tiny rock. Geology looks at the processes that formed the Earth, and Geography looks at the Earth’s Surface, atmosphere, hydrosphere, biosphere, and at the people who inhabit it.
