At the time of lunar eclipse, the phase of the Moon is

Which of these factors makes it far more likely that a person will have seen a total lunar eclipse than a total solar eclipse?

If an observer is at the equator, how would they describe the angle with the horizon made by stars as they rise and set?

An observer on the equator will be able to see what fraction of the overall sky over a period of 1 year?

The reason Earth experiences seasons is that

The change in the declination of the Sun between December 21 and June 21 is approximately

Eclipses of the Moon can occur

When the Moon is at new Moon phase, what percentage of the area of the Moon illuminated by the Sun can an observer see from Earth?

The Moon will appear to an observer at mid-latitudes on Earth to rise in the east, in solar time, about ( might attempt to verify this by observation!)

Which of these bodies will never be seen from Earth as a crescent?

For an observer at a fixed location on Earth, the angle between the north celestial pole and an observer's horizon depends on the

According to an observer on the Moon, which of these bodies could occasionally appear as crescent shaped?

There is about a 5° angle between the orbit of the Moon and the

The "Land of the Midnight Sun" is so-named because

Earth's shadow at a distance of the Moon's orbit from Earth is

If an observer could watch the Sun moving day by day against the background stars, it would follow

If both the direction of Earth's rotation about its axis and the direction of its revolution around the Sun were reversed, the length of a sidereal day would be

When does the third-quarter Moon rise?
