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 is close to zero, the center of the orbit is relatively close to the center of the Sun (relative to the size of the orbit).
If you’re looking forward to spring, you’re not alone. But it’s not just Easter and Mother’s Day that you might want to pencil in on your calendar—Earth Day falls on April 22 this year ...
Exaggerated illustration of Earth's elliptical orbit around the Sun, marking that the orbital extreme points (apoapsis and periapsis) are not the same as the four seasonal extreme points, the equinox and solstice. Earth orbits the Sun, making Earth the third-closest planet to the Sun and part of the inner Solar System.
Average altitude of 384,403 kilometres (238,857 mi), elliptical-inclined orbit. Beyond-low Earth orbit (BLEO) and beyond Earth orbit (BEO) are a broad class of orbits that are energetically farther out than low Earth orbit or require an insertion into a heliocentric orbit as part of a journey that may require multiple orbital insertions ...
YouTube has also presented advocacy campaigns through special playlists featured on YouTube Kids, including "#ReadAlong" (a series of videos, primarily featuring kinetic typography) to promote literacy, [12] "#TodayILearned" (which featured a playlist of STEM-oriented programs and videos), [13] and "Make it Healthy, Make it Fun" (a ...
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
The Voyager Golden Records are two identical phonograph records one of each which were included aboard the two Voyager spacecraft launched in 1977. [1] The records contain sounds and data to reconstruct raster scan images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form who may find them.
