Within each orbit, collisions between planetesimals generated immense heat and energy.───在每个轨道内，天体之间的碰撞产生了巨大的热量和能量。
We must imagine the early Earth as a mixture of rocky materials, metals, and trapped gases, subject to constant bombardment by smaller planetesimals and without much of an atmosphere.───我们必须想象早期的地球是岩石材料、金属和封闭气的混合物，受到较小的星子的持续轰击，没有多少大气。
This material gradually coalesced into lumps called planetesimals as gravity and chance smashed smaller pieces together.───随着重力和机会将较小的碎片粉碎在一起，这种物质逐渐聚集成块状，被称为天体。
Over the next 100 million years, the planets swept up some of these planetesimals and deflected the rest into the sun.───接下来的一亿年里，行星清除了一部份的微行星，并迫使其他的微行星偏折而投入太阳之中。
But a recent study by an MIT planetary scientist suggests that the planetesimals themselves provided the water that created oceans.───但最近进行的一项麻省理工学院的行星科学家的研究表明，星子（planetesimals）自己提供了形成海洋的水。
While this process had been modeled previously, no one had investigated whether water in planetesimals could produce oceans.───虽然这进程以前已经建模但没有人确定星子（planetesimals）中的水能否产生海洋。
Small town with the state, from large roadside and the planetesimals out of the officials most is the fire dragon dance to bring luck then?───小城连州，从大路边与星子出的官员最多，是不是舞火龙带来的运气呢？
The planets transferred their random motion to the doomed planetesimals and entered into circular or almost circular orbits.───行星因此把它们随机运动的动量，移转给那些命运悲惨的微行星，而进入近乎圆形的轨道中。
The Earth was made by the collision of billions of planetesimals, chunks of rock and ice much like today's asteroids and comets .───地球是由数十亿颗星子（即由大块岩石、像今天的小行星和慧星般大小的冰组成）碰撞而成。
The planetesimals accretions of the Earth obviously have two stages, including initial accretion and late accretion.
By collision and gravitational attraction, the larger planetesimals swept up the smaller pieces and became the planets.
The fragments may well have been primordial planetesimals, according to Weaver.
Part of such planetesimals entered the asteroid region, drew out most of the matter there, and increased the random velocity of the asteroids that remained, so they could not combine to form a planet.
Carbonaceous chondrite planetesimals were adsorbed on the mantle surface of the primitive earth, forming primitive carbon-rich areas.
