According to experts, on the Spring Equinox and Autumn Equinox, the earth’s axis(轴), on its 66.5 degree tilt, is in a relative balance of power with the earth’s orbit around the sun. Thus it is an ___10___ (easy...
The path of the earth around the sun is an elliptical shaped orbit. But it should be noted that the exact path of the planet changes slightly over time. These changes in orbit can affect certain natural events on the planet, like weather and climate. ...

in Antarctica (南极洲) in 1983. We encounter an interesting situation when we discuss temperatures in (52) . Temperatures in Earth orbit (轨道) actually range from about +120℃ to --120℃. The temperature depends upon (53) you are in direct sunlight or shade. Obviously, -120℃ is ...
(n-1)! for odd n n , and n(n-2)! n(n-2)! for even n n . We prove that if p p is the largest prime with p\\leq n p\\leq n , then \\max_{v,H} |H\\cap S_nv|\\leq \\frac{n!}{p} \\max_{v,H} |H\\cap S_nv|\\leq \\frac{n!}{p} . In particular,...
In fact,NASA saysthat geostationary orbits are achieved by selecting a geosynchronous orbit that is perfectly circular described as having an eccentricity of 0 and an inclination of 0 right on the equator, or low enough that it can use propulsion to maintain its position over Earth. ...
