矮星

Ceres is the smallest identified dwarf planet in the Solar System and the only one in the asteroid belt.

谷神星，太阳系已知的最小的矮行星，也是唯一位于小行星带的矮行星。

When Black cornered Pettigrew on a busy street, Peter created an explosion with his wand, cutting off a finger from his own right hand in the process, and disappeared.

当布莱克把小矮星彼德困在一个繁华的街角时，彼德用魔杖制造了一场爆炸，断掉自己的一根右手指并且消失了。

Orbiting a Red Dwarf Star Image of the Day Gallery Orbiting a Red Dwarf Star This artist's concept of a gas giant planet orbiting a red dwarf K star shows a planet has not been directly imaged , but its presence was detected in 2003 microlensing observations of a field star in our galaxy .

此图本意是拍摄一颗环绕红矮星K运行的由气体组成的巨大行星，但并未直接对其成像，不过该行星的踪迹在2003年针对银河系中恒星带的引力透镜现象进行观测时被发现。

"I don't want a connection with Pettigrew!"

&我才不想和小矮星彼特有什么联系！&

If Planet X is a protostar or brown dwarf it absorbs almost all the light, hence is very dark.

如果行星x是颗原恒星或者棕矮星，它会吸收几乎全部的阳光，因而非常暗淡。

Tennis transformed her from a tall (5-foot-10, though my guess is she's at least an inch taller) giggly, seemingly harmless teenager, and later an elegant woman (hence her new gig on Dancing with the Stars ), into a feisty competitor who looked, frankly, like a pipsqueak compared to Graf (who is, by the way, an inch shorter that Seles).

网球让他从一个身材高挑（5英尺10英寸，虽然我猜她还要再高个几英寸）的小姑娘，一个看上去毫无戒心的年轻人，一个文雅端庄的女士（正如她在&与星共舞&里的最新表演），变成了一位积极勇猛的运动员，老实说，甚至让她看上去比格拉芙还矮了点（事实上格拉芙要比塞莱斯矮一英寸）。

特殊的物质，以致于她的亮度要比标准的M6.5红矮星要暗。

It must be satisfying to actually find a dwarf planet.

发现那颗矮星的时候一定相当让人满足。

How much hate mail do you get since you killed the poor little dwarf planet?

你收到多少封&仇恨邮件&自从你谋杀了那颗可怜的小矮星后？

A planet on the other hand is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.

行星演化与恒星不同：恒星形成之后，周边的气体尘埃云冷却之后凝结形成，成为行星雏形，众多小行星雏形聚合碰撞，演化成成熟的行星；没有内部的核聚变；质量超过木星13.6倍，就会产生核聚变，如果还未至木星86倍，尚处于棕矮星的阶段，将会向恒星演化；持久的核聚变需要足够大的质量来支撑，温度也不足支撑氢向氦的转变。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
