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.

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.

This poor world, the object of so much insane attachment, we are about to leave; it is but misery, vanity, and folly; a phantom, — the very fashion of which "passeth away."
François Fénelon, reported in Josiah Hotchkiss Gilbert, Dictionary of Burning Words of Brilliant Writers (1895), p. 206.
Thanks to a recent EU-funded study, geological chemists now understand how tectonic plates and convection in the mantle are connected.
