Moon questions This is a list of recently added questions about Moon. Play Moon quiz and see all the questions. Is the Moon's orbit around the Earth constant?It is slowly increasing. For several hundred million years, the Moon has gone so far that it will no longer be possible to complete the solar eclipse.Created by: Katarzyna Dąbrowskahard 50% It is constant.It is constant.1585It is slowly increasing.It is slowly increasing.3357It is slowly decreasing.It is slowly decreasing.1040It is impossible to measure.It is impossible to measure.687astronomy riddles » What is larger on the sky: the Moon or the Sun? (by apparent size)Sometimes the Moon, sometimes the Sun. The Moon's orbit is elliptical, and its apparent diameter varies by 10%. This is why both total eclipses (if the Moon is larger) and annular eclipses (if the Sun is larger) happen.Created by: pan Krzyżówkahard 43% the Sunthe Sun1984the Moonthe Moon2496both are identicalboth are identical1580sometimes the Moon, sometimes the Sunsometimes the Moon, sometimes the Sun4598Sun riddles » How long did Neil Armstrong’s first moon walk last?2½ hours.

How many other moons in the Solar System share this feature?Most of them. If the rotational frequency of satellite is larger than orbital frequency, a small torque counteracting the rotation arises, eventually locking the frequencies in a tidal lock. Pluto and Charon are the extreme example, being locked to each other.Created by: globalquiz.orghard 43% nonenone5661oneone2639threethree1648most of themmost of them7693Solar System riddles » What kind of 'natural disasters' happen on the moon?Moonquakes are produced by tidal forces. Moonquakres are much less common and weaker than earthquakes, although they can last for up to an hour - a significantly longer time than terrestrial earthquakes - because of the absence of water to damp out the seismic vibrations.Created by: life-o-holichard 49% volcanic eruptionsvolcanic eruptions2420moonquakesmoonquakes9374floodsfloods432dust stormsdust storms6797astronomy riddles » What part of the Moon surface had been known to humanity before the first photos of the dark side were taken in 1959?59%. Moon's libration changes the angle from which the Moon is seen, allowing about 59% of its surface to be seen from the Earth (but only half at any instant). Moon's libration is caused by the eccentricity of its orbit around Earth and by a slight inclination of its axis of rotation.Created by: globalquiz.orgaverage 62% 52%52%661359%59%1481281%81%1659100%100%728technology riddles » How many people stood on the Moon so far?Twelve.
