Ⅱ.阅读理解Passage 1When we talk about how the Earth and the other planets travel around the sun, we say they orbit the sun.Likewise, the moon orbits the Earth. Many artificial satellites(人造卫星) also orbit the Earth.Satellites can orbit the Earth's equator(赤道) or go over the Earth...
From the moon’s perspective, the Earth has an extra lump, which creates an extra gravitational pull. That pull from the tide tugs on the Moon like a leash on a reluctant dog, adding energy to the moon’s orbit and causing it to drift away. Since that energy has to come from ...
This is because the movement of the Moon in orbit around the Earth due to inconsistent with the rotation of the Earth in the process. We all know, a metal soluble nuclear core of the center of the Earth, is a mass of very high temperature plasmas. When the Earth at the time of trans...
4.The moon's orbit is not perfectly round, so the moon does get nearer and farther away over the course of a month.It's easy to test the moon illusion, and you can do it yourself. Next time you see the moon looking bigger than usual, hold out your hand with a straight arm. 5....
The phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight. Thanks to the Moon’s orbit around Earth, the angle of sunlight hitting the lunar surfa...

a A shadow is cast on the moon during a lunar eclipse in Bogota, Colombia March 3, 2008. A lunar eclipse occurs when the moon in orbit around the Earth passes through the earth‘s shadow, which can be seen cast on to the moon.[translate]...
This "supermoon" was at perigee (近地点)—its closest point to the earth in its orbit. It was bigger and brighter than other full moons of 2011. Astronomers call this sort of close full moon a perigee full moon.That doesn't sound very special, does it? In fact, the March 2011 full...
Finally, the moon moves back to itsnew moonstarting position. Because the moon’s orbit is not exactly in the same plane as Earth’s orbit around the sun, they rarely are perfectly aligned. Usually the moon passes above or below the sun from our vantage point, but occasionally it passes ...
New moons occur approximately once every month because that's roughly how long it takes for the moon to orbit Earth. But because the moon's orbit is slightly tilted relative to Earth's orbit around the sun, it doesn't block out the sun on every orbit, hence why not every new moon res...
