百万秒差距 meaning in Chinese

megaparsec

If we know the value of the hubble s constant , we can determine the distance of a galaxy by means of hubble s law
例如上例中的星系，如果哈勃常数是60的话，它便距离地球150百万秒差距。
Typically , a cluster of galaxies contains 1000 galaxies within a million parsecs . in a larger scale , clusters group together to form
一个典型的星系团大小约一百万秒差距，包含大约1000个星系。
513km s mpc , ie , for a celestial object 1 , 000 , 000 parsec away from us , its recession rate is 513km 1 parsec 3 . 26 light years
513 km s mpc ，即一个距离我们一百万秒差距的天体，它的退行速度是每秒513公里一秒差距3 . 26光年。
This means galaxies further away will move away faster . one could argue that the hubble s constant is the most difficult parameter to measure in astronomy . different astronomers using different methods have found different values of h . it ranges from 50km s mpc to about 100km s mpc , with the most accepted value around 60km s mpc
哈勃常数可能是最难以量度的天文参数，不同的天文学家用不同的方法，得出不同的结果，计算出的数值由50公里秒百万秒差距至100公里秒百万秒差距不等，现在最被广泛接受的数值约为60公里秒百万秒差距。
