Eclipse -- An eclipse occurs when an astronomical body such as a planet, or satellite gets between a source of light (e.g. the Sun) and another body. For instance, Jupiter eclipses its moons when it gets between them and the Sun. -- Lunar eclipses - are where the Earth obscures the Sun, from the Moon's point of view. The Moon moves through the shadow cast by the Earth. This can only happen...

Crater

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is...

The words moon and month come from the same Old English root word....

Lunar Phase -- The lunar phase is an astronomical term referring to the portion of the Moon that is visibly illuminated by the Sun, as seen from Earth. As the Moon orbits the Earth, the relative positions of the Sun, Earth and Moon change. Since the Moon only appears bright due to the Sun's reflected light, only the half of the Moon closest to the Sun is illuminated. Lunar phases are...

The Planet Venus is the second planet from the sun. It is often called the evening star or morning star and is brighter than any object in the sky except the sun and the moon. Because its orbit lies between the sun and the orbit of the earth, Venus passes through phases like those of the moon, varying from a large bright crescent when the planet is near inferior conjunction (nearest the...

Earth

Earth -- in geology and astronomy, fifth largest planet of the solar system and the only planet definitely known to support life. Gravitational forces have molded the earth, like all celestial bodies, into a spherical shape. However, the earth is not an exact sphere, being slightly flattened at the poles and bulging at the equator. The equatorial diameter is c.7,926 mi (12,760 km) and the...
