synodic month

We had observed more than ten selected asteroids using 1 - meter telescope in yunnan observatory during 2000 to 2002 . the observational data of seven asteroids had been reduced and analyzed . we have derived their synodic periods and estimated the shape and orientation of rotational axis for one asteroid 為此,我選定了一些直徑在125公里左右的小行星進行觀測和分析;一方面,測定它們的自轉周期,進行“角動量衰減”現象的研究,另一方面,對小行星形狀和自轉軸指向進行估算,為小行星碰撞演化研究提供更為有利的證據。

Here we assume planets move in circular motion at constant speed , and the synodic periods given above is just an approximate value . actually the planetary motion is full of small variants , and the synodic period values are irrational number . the quotient of two irrational numbers cannot be written as a fraction 最新的消息是,在2000年10月后的六星期內,竟然一口氣為土星多發現10顆衛星,讓它在剎那間重新超越天王星,成為最星多勢眾的行星,現在土星有28顆衛星,遙遙領先只有21顆衛星的天王星,木星的衛星數目為18顆,而第四位的海王星則只有8顆。

Is 29 . 5 days . interestingly , the rotational period of the moon relative to the sun is exactly the same as the synodic period 盈虧月。月球的自轉周期剛好和它的繞地公轉周期相等,這種情形稱為

Its synodic period brings it into conjunction with the sun every 398 days and 88 minutes , a little more than a year 它與太陽關聯的會合周期是398天零88分,比一年稍長一些。

The time between successive new moons , the synodic period 兩次新月之間相隔29 . 5日,這個盈虧周期稱為
