These little blobs are called planetesimals — wee baby planets.

这些小斑块被称为微——也就是婴儿状态。

The researchers wrote that a straightforward explanation for Oumuamua is that it is a planetesimal.

研究人员写道，“最直观的解释是：'奥陌陌’是颗微”。

And how does the chaos and turmoil of dust become pebbles, and pebbles become boulders, and boulders become planetesimals?

It is classified as a planetesimal — objects that were among the original building blocks of our solar system.

它被归类为子——子是太阳系最初的组成部分之。

Planetesimals were also scattered further out, including the dwarf planets Sedna and Eris, discovered in 2003 and 2005. The NIS model works well for many starting scenarios for the Solar System.

些微被捕获成为卫， 另些则占据了特洛伊群的稳轨道， 还有些可能进入了小带。 微也被散布到更远的地方，包括2003年和2005年发现的小塞德娜和阋神。NIS模型在许多太阳系起始情景中表现良好。

What makes Psyche so special is that it appears to have been a planetesimal well on its way to becoming a planet, with a rocky exterior surrounding a metal core.

使得赛克丝如此特别的原因在于， 它似乎曾经是子， 正在向化，其岩石外壳包裹着属核心。

In the model proposed by researchers, it is assumed that Oumuamua began its journey as an icy planetesimal.

在研究人员提出的模型中，假设奥陌陌最初是颗冰质子。

The ice giants swept through the remaining planetesimal disk, scattering most of it, to create what is known as the Late Heavy Bombardment, which occurred about 4 billion years ago.

冰巨横扫剩余的微盘，将其大部分散射开来， 从而引发了所谓的晚期重轰炸，这事件大约发生在40亿年前。 数以万计的陨石从外盘被抛射而出， 如雨般倾泻在内上。

Dust and gas orbiting our young sun cooled and collided to form a few thousand miniature bodies we call planetesimals.

围绕我们年轻太阳旋转的尘埃和气体冷却并相互碰撞，形成了几千我们称之为子的小型天体。

Planetesimals encountering Jupiter's powerful gravity were fired out to the edge of the Solar System to form the Oort cloud, and this had the effect of shifting Jupiter inwards.

遭遇木强大引力的子被抛射到太阳系的边缘， 形成了奥尔特云，这过程导致木向内移动。

But its progress was cut short by a series of hit-and-run collisions with other planetesimals that knocked off the rocky crust until only the core remained.

然而，它的发展被系列与其他子的碰撞打断，这些碰撞将其岩石地壳剥离，直到只剩下核心。

The giant planets pulled these planetesimals inwards, and in return, Saturn, Uranus and Neptune started slowly edging further away from the Sun.

巨将这些小天体向内拉，作为回应， 土、天王和海王则开始缓慢地逐渐远离太阳。

The planets formed from planetesimals that join together by the process of accretion.

通过吸积过程，由微聚集而成。

Today, Safronov's planetesimal hypothesis of planet formation is widely accepted, although alternative theories exist.

如今， 萨弗罗诺夫的形成微假说已被广泛接受，尽管还存在其他理论。

As they grew bigger, the gravity of each particle would cause them to coalesce, forming larger objects called planetesimals.

随着它们体积增大， 每粒子的引力会使它们聚合，形成被称为子的更大天体。

A spherical region at the edge of the solar system containing planetesimals and comets.

位于太阳系边缘的球形区域，包含小和彗。

Some planetesimals were captured by the planets to become moons, others filled stable orbits as Trojans, and some may have entered the asteroid belt.

些微被捕获成为卫，另些则占据了稳的轨道成为特洛伊小，还有些可能进入了小带。

In 2008, one researcher suggested that Venus may have gotten its weird spin back when it was a wee li'l planetesimal.

2008年，位研究人员提出，可能在其还是小微时就获得了这种奇怪的自转方式。
