圍繞這樣一顆無生命的恆星運行的行星上不可能有生命存在。Earth satellite vehicle
地球衛星運載火箭But starting with the 1995 discovery of the first extrasolar planet a gassy monster like jupiter but orbiting seven times as close to its star as mercury orbits around our sun each new find has seemed stranger than the last
但1995年發現了第一顆太陽系之外的行星一顆像木星一樣的巨大氣態星球，它圍繞自己的母星運行的距離比水星繞著太陽運行時的距離還近7倍。For example, if there is a planet orbiting around the neutron star, it will wobble a little and the pulses will come a little early or late. we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses. this is how the first extrasolar planet is discovered
例如假若有一顆行星圍繞一顆中子星運行，它會令中子星出現搖動，引致脈沖的間隔變長或短，由此我們根據脈沖周期的變化，可推斷出行星的質量和軌道半徑，這亦是天文學家找出第一顆地外行星時所用的方法。The mission was cancelled until the next launch window which will be exactly three weeks from today
太空任務取消了，要等到下次行星運轉的位置對發射有利的時機再進行，那時正好是3個星期之後。Occultation complete or partial obscuration of an astronomical object by the moon or a planet

恆星運動方向與視線之間的夾角。With additional capabilities in rotorcraft, electronic and defense systems, missiles, rocket engines, satellites, launch vehicles and advanced information and communication systems, the company ' s reach extends to customers in 145 countries
加上旋翼飛機、電子和防禦系統、導彈、火箭發動機、衛星、運載火箭和先進信息及通訊系統等方面的研製能力，本公司的客戶已經遍及145個國家。The bulk of the mass is spread out, forcing stars to trace a spirograph - like rosette : an ellipse that does not close on itself but gets offset each time the star completes one revolution [ see box at right ]
整體質量分散開來，迫使恆星運行方式如旋轉繪圖盤所畫出的花瓣狀螺線：那不是每圈都會封閉起來的橢圓，恆星繞行一周后，軌道並不接合便又重新開始下一周的運動（見右方整理軌道秩序） 。Be responsible for package on sporadic transportation
負責零星運輸中的包裝環節。Said dr. james w. head iii, a professor of geological sciences. photographs taken by a spacecraft orbiting mars indicate that active volcanoes may still exist on the planet
言出地質學專家海德博士.由一艘繞火星運行的飛船所拍攝的照片顯示火星上仍有可能存在著活火山Boeing enters into agreement with russian company for 787 pa
美國波音公司演示轉型衛星運行能力A planet that may be earth - like - but too hot for life as we know it - has been discovered orbiting a nearby star
最近，天文學家新發現了一顆類地行星，它圍繞著附近的一顆恆星運轉。但從已知情況來看，其表面溫度太高，不適合生命生存。Although we may never be able to verify this hypothesis on earth, we may be able to test it indirectly by observing earth - like planets orbiting other stars
縱使這個假說可能永遠無法在地球上獲得驗證，但藉由觀測環繞其他恆星運行的類地行星，或許能間接驗證。As a companion star orbits its primary, it alternately approaches and recedes from the earth.
當伴星圍繞著主星運轉時，它交替地朝著地球或背離地球運轉。Small planets ' waves have small amplitudes, so you can pick the signal from the noise only after several orbits
較小行星的波振幅不大，因此科學家只能在它們圍繞恆星運行數次后才能從噪音中收集到訊號。The pictures radioed back by spacecraft that have orbited and landed on mars show a host of intriguing geologic structures.
從圍繞火星運行和在火星上著陸的宇宙飛船所傳回來的照片上，可以看到一大批令人感興趣的地質結構。And this measurement, in turn, would allow scientists to estimate not only the distance between earth and the sun but also the scale of the entire solar system
天文學家已經由克卜勒的行星運動定律知道所有行星和太陽的相對距離，所以他們能夠由金星視差計算出太陽視差，讓科學家得以估計地球與太陽的距離，以及整個太陽系的尺度。分享友人
