Constellation is very popular in recent years, the word, for all of us know more or less some constellation, constellation can let us more clear and understanding to his own character, today small make up just to bring us some constellation judgement method of character, like friends and have a look!

Constellation looks with the celestial sphere movement is caused by the earth's own movement, which is significant to the stars change is the earth's rotation and revolution.Due to the earth's rotation, the starry sky background around the shaft rotating ring every day;The stars also slowly changing along with the change of season, after a year later, the stars and the sky almost a year ago.Turning of the earth's rotation axis and a long periodic motion is called precession, the cycle is about 25765 years.This movement caused the North Pole in the background of this star periodic drift, it called precession in astronomy.In a short period of constellation rough observation can ignore this motion.

The stars are doing high-speed mobile.Direction of movement of the stars can be decomposed into two attachment of radial velocity and the vertical themselves, including their own will change depending on the location of stars in the sky.Because the star is too far away from the earth, can generally think that the position of the stars in the sky are fixed.

Due to the sun and the planets the apparent position relative to the earth and the position of the background stars on the celestial sphere is not fixed, they periodically across 13 constellations on the ecliptic.In astrology, often with "mercury inScorpio"In the way described.But the ecliptic only on astrologyThe zodiacAnd are equally spaced.

Sign in a long time ago sailors and travelers as to identify the direction of the important marks.Along with the development of science and technology, the zodiac is used in the direction of action, but the spacecraft is by identifying the bright stars to determine its own position and heading.For the starry sky enthusiasts, constellation recognition is often of bright stars.

Little dipper in the northern half of the north star is in the stars to determine the direction of the most important basis.As can be seen from the celestial coordinate system, the height of the pole star is consistent with the local latitude;But in fact, due to the north star is not bright, people usually use the big dipper to find Polaris, which determine the direction.The big dipper handle (beta, to alpha) five times of the extension can find the north star.In the case of accuracy is not high, can be thought of as the direction of the north star in the north.In low latitudes in the northern hemisphere, the big dipper will fall below the horizon, at this time may, in accordance with the relative, the big dipper "M" (or "W") of Cassiopeia determines the location of the north star.(the zodiac/astro /)

Everybody now for constellation of the character of the judgment methods learned!If you think good, also can have a try!
