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.

And again, observe ye the days of summer how the sun is above the earth over against it. And you seek shade and shelter by reason of the heat of the sun, and the earth also burns with growing heat, and so you cannot tread on the earth, or on a rock by reason of its heat.

Book of Enoch, Chapter 4, translated by Robert Charles, 1917.
