Earth orbits(环绕) the sun in 365 days. T his makes one Earth year 365 days long.Earth has big oceans and a lot of watervapor(水蒸气) in the air. Earth has clouds made of water vapor. Earth has an atmospherewith a lot of oxygen (氧气) in it for us to breathe. T he rest of...
As long ago as 1978, Donald Kessler, a scientist at NASA, proposed a scenario (设想) in which, when enough satellites were packed into low-Earth orbits, any collision could cause a chain reaction which would eventually destroy all spacecraft in its orbital plane. Solutions exist. One ...
The earth revolves about the sun once in a period of a little more than 3651-4 days (a year). The path of this revolution, the earth's orbit, is an ellipse rather than a circle, and the earth is consequently nearer to the sun in January than it is in July; the difference between...

While Earth orbits the sun, the planet is simultaneously spinning around an imaginary line called an axis that runs through the core, from the North Pole to the South Pole. It takes Earth 23.934 hours to complete a rotation on its axis and 365.26 days to complete an orbit around the sun ...

The Earth orbits the Sun not in a perfect circle, but rather in an ellipse. The eccentricity, or the difference between the “long axis” and the “short axis” of our orbit, changes over time, while the Earth-Sun orbital period, which defines our year, changes slowly over the lifetime...
Sun, earth and moon animation In this animation, three images of The Sun, Earth and the Moon are used. The Sun remains stationary; Earth orbits the sun in 365 days; The Moon orbits Earth in 28 days. Using both sine and cosine functions of trigonometry, the positions of orbits are calcul...
Earth - Planet, Atmosphere, Geology: The mean distance of Earth from the Sun is about 149,600,000 km (92,960,000 miles). The planet orbits the Sun in a path that is presently more nearly a circle (less eccentric) than are the orbits of all but two of the
