Orbit : Nasa Astronauts Photograph the Earth A beautiful coffee table book . Kids often ask me which is my favorite planet. My answer is always "Earth". This book shows why. Earth is the only planet whose English name does not derive from Greek/Roman mythology. The name derives from Old English and Germanic. There are, of course, hundreds of other names for the planet in other languages . In Roman Mythology, the goddess of the Earth was Tellus - the fertile soil (Greek: Gaia terra mater - Mother Earth). It was not until the time of Copernicus (the sixteenth century) that it was understood that the Earth is just another planet. Mir space station and Earth's limb Earth, of course, can be studied without the aid of spacecraft. Nevertheless it was not until the twentieth century that we had maps of the entire planet. Pictures of the planet taken from space are of considerable importance; for example, they are an enormous help in weather prediction and especially in tracking and predicting hurricanes. And they are extraordinarily beautiful. The Earth is divided into several layers which have distinct chemical and seismic properties (depths in km):

About Planet Earth The Earth, which is located three planets from the Sun , is the only planet in the universe known to support any kind of life. The Earth is estimated to be approximately 4.57 billion years old. The moon followed not long after. The Earth rotates around its own north to south axis once every 23 hours, 56 minutes and 4.091 seconds (one day), and around the Sun once every 365.2564 days (one year). The Earth formed when the initial molten lava mass cooled and formed a solid outer crust. The Earth’s approximation to the Sun and ability to absorb its solar energy allowed for photosynthesis to occur. This began the accumulation and storage of oxygen in the Earth’s atmosphere and the development of what we now know as the ozone layer. Early eukaryotic life on Earth soon followed. With the complete formation of the ozone layer, which blocked all harmful ultraviolet radiation from the Sun, multicellular life began to slowly populate the planet. Following several major catastrophic life extinctions, mankind’s first ancestors slowly began to evolve, beginning the early stages of what has lead to the world as we know it today.

From space, astronauts often get the impression that the Earth is small with a thin, fragile layer of atmosphere. For a space traveler, the distinguishing Earth features are the blue waters, brown and green land masses and white clouds set against a black background. Many dream of traveling in space and viewing the wonders of the universe. In reality all of us are space travelers. Our spaceship is the planet Earth, traveling at the speed of 108,000 kilometers (67,000 miles) an hour. Earth is the 3rd planet from the Sun at a distance of about 150 million kilometers (93.2 million miles). It takes 365.256 days for the Earth to travel around the Sun and 23.9345 hours for the Earth rotate a complete revolution. It has a diameter of 12,756 kilometers (7,973 miles), only a few hundred kilometers larger than that of Venus. Our atmosphere is composed of 78 percent nitrogen, 21 percent oxygen and 1 percent other constituents.

He compared the midsummer's noon shadow in deep wells in Syene (now Aswan on the Nile in Egypt) and Alexandria. He properly assumed that the Sun's rays are virtually parallel (since the Sun is so far away). Knowing the distance between the two locations, he calculated the circumference of the Earth to be 250,000 stadia. Exactly how long a stadia is is unknown, so his accuracy is uncertain, but he was very close. He also accurately measured the tilt of the Earth's axis and the distance to the sun and moon.
