Moon questions This is a list of recently added questions about Moon. 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 Sun1913the Moonthe Moon2385both are identicalboth are identical1499sometimes the Moon, sometimes the Sunsometimes the Moon, sometimes the Sun4384Sun 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% nonenone5357oneone2489threethree1555most of themmost of them7252Solar 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 48% volcanic eruptionsvolcanic eruptions2297moonquakesmoonquakes8792floodsfloods418dust stormsdust storms6438astronomy 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 61% 50%50%626159%59%1381780%80%1575100%100%687technology riddles » How many people stood on the Moon so far?Twelve.
