太空矮人介绍英文作文初中
英文：
Space dwarfs are a type of celestial body that is smaller than a planet but larger than an asteroid. They are also known as dwarf planets and are part of the Kuiper Belt, a region beyond the orbit of Neptune that is home to many
icy objects. The most famous space dwarf is Pluto, which
was once considered the ninth planet in our solar system
but was later reclassified as a dwarf planet.
Space dwarfs are interesting because they have some characteristics of both planets and asteroids. They are
large enough to have a spherical shape, which is a defining feature of planets, but they have not cleared their orbit
of other debris, which is a requirement for a planet. Instead, they share their orbit with other objects and are often located in regions with many other space dwarfs.
Despite their small size, space dwarfs are important
objects for astronomers to study. They can tell us about the formation and evolution of our solar system and provide clues about the conditions that existed when the planets were formed. For example, some space dwarfs have moons, which can reveal information about the collisions and interactions that occurred in the early solar system.
Overall, space dwarfs are fascinating celestial bodies that have much to teach us about our solar system and the universe as a whole.

太空矮人是一种比行星小但比小行星大的天体。

它们也被称为矮行星，是柯伊伯带的一部分，柯伊伯带是海王星轨道之外的一个区域，有许多冰质物体。

最著名的太空矮人是冥王星，曾经被认为是我们太阳系中的第九颗行星，但后来被重新归类为矮行星。

太空矮人很有趣，因为它们具有行星和小行星的一些特征。

它们足够大，可以呈现球形，这是行星的一个定义特征，但它们没有清理掉其轨道上的其他碎片，这是行星的一个要求。

相反，它们与其他物体共享其轨道，通常位于许多其他太空矮人的区域。

尽管它们体积较小，但太空矮人对于天文学家来说是重要的研究对象。

它们可以告诉我们有关我们太阳系的形成和演化的信息，并提供有关行星形成时存在的条件的线索。

例如，一些太空矮人拥有卫星，这可以揭示早期太阳系中发生的碰撞和相互作用的信息。

总体而言，太空矮人是迷人的天体，它们有很多可以教给我们关于我们太阳系和整个宇宙的知识。
