Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution. Earth rotates around its own axis in slightly less than a day (in about 23 hours and 56 minutes). Earth's axis of rotation is tilted with respect to the perpendicular to its orbital plane around the Sun, producing ...
[35] [n 4] Multiplying by (180°/π radians) × (86,400 seconds/day) yields 360.985 6 °/day, indicating that Earth rotates more than 360 degrees relative to the fixed stars in one solar day. Earth's movement along its nearly circular orbit while it is rotating once around its axis requires that Earth rotate slightly more than once relative to ...
One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). [2] Ignoring the influence of other Solar System bodies, Earth's orbit, also called Earth's revolution, is an ellipse with the Earth–Sun barycenter as one focus with a current eccentricity of 0.0167. Since this value ...
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of over 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.

By: Troy Frisby/Patrick Jones, Buzz60 NASA's new pictures of Earth are reigniting conspiracy theories straight out of "Journey to the Center of the Earth."
The Images of Change project provides side-by-side photos of the same place over time to document the environment changes caused by nature and man. NASA's before and after images show Earth's ...
Earth - Apollo 17 Full Earth showing Africa and Antarctica Apollo 17 hand-held Hasselblad picture of the full Earth. This picture was taken on 7 December 1972, as the spacecraft traveled to the moon as the last of the Apollo missions. A remarkably cloud-free Africa is at upper left, stretching down to the center of the image.
