Earth
Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.
Earth
We travel together, passengers on a little space ship, dependent on its vulnerable reserves of air and soil; all committed for our safety to its security and peace; preserved from annihilation only by the care, the work, and, I will say, the love we give our fragile craft. We cannot maintain it half fortunate, half miserable, half confident, half despairing, half slave—to the ancient enemies of man—half free in a liberation of resources undreamed of until this day. No craft, no crew can travel safely with such vast contradictions. On their resolution depends the survival of us all.
Adlai Stevenson, U.S. ambassador to the United Nations, last major speech, to the Economic and Social Council of the United Nations, Geneva, Switzerland (July 9, 1965); in Albert Roland, Richard Wilson, and Michael Rahill, eds., Adlai Stevenson of the United Nations (1965), p. 224.

Simonson, in rubber jacket and similar galoshes, bound with whip-cord over woolen socks (he was a vegetarian and did not use the skin of animals), was also awaiting the departure of the party. He stood near the entrance of the house, writing down in a note-book a thought that occurred to him. “If,” he wrote, “a bacterium were to observe and analyze the nail of a man, it would declare him an inorganic being. Similarly, from an observation of the earth’s surface, we declare it to be inorganic. That is wrong.”
Leo Tolstoy, Resurrection (1899), translated by William E. Smith, ch. 83.

Earth below us
drifting, falling.
Floating weightless
calling, calling home...
Peter Schilling, song Major Tom (Coming Home) (1983).
Combustion of fossil fuels for the heating, cooling and electricity needs of a large factory produces substantial emissions and detrimental impact on the environment. Harnessing thermal energy from the Sun may soon be a cost-effective alternative.
