Query: Earth's orbit path around the sun
Useful Output:

Doc 1: When Earth is closest to the Sun in its orbit, it is at "perihelion." That distance is 147,166,462 kilometers, and Earth gets there each January
Doc 2: The seasonal changes on Earth are because of the 23.44° axial tilt of its rotation and slightly elliptical path around the Sun. The orbit varies over long
Doc 3: Earth orbits the sun once a year and rotates on its axis once a day. The Earth's orbit makes a circle around the sun. At the same time the Earth
Doc 4: We saw that the Earth satisfies Kepler's law for objects orbiting the Sun; meanwhile the Sun does not satisfy the similar law for objects
Doc 5: Earth, however, like the tetherball, is traveling forward at a high rate of speed, which balances the gravitational effect. This means that the planet neither
