矮行星

It is just weeks since Pluto was redefined as a dwarf planet .

冥王星被重新定义为矮行星只是几个星期前的事。

To understand this, we must look at the cosmology of the day of the formation and then we find out that the sun on this day is in conjunction with the dwarf planet Sedna!

要理解这一点，我们必须看看在当天的形成宇宙，然后我们发现，在这一天的太阳与矮行星塞德娜一起啊！

Now Pluto will be called a dwarf planet along with at least two others.

现在冥王星和至少其他两个将被称为矮行星。

According to IAU, a "dwarf planet" should have an orbit around the Sun.

国际天文学联合会的意见认为，&矮行星&应该绕太阳沿轨道运转。

Pluto is now classified as a "dwarf planet".

冥王星现在被归类为&矮行星&。

Ris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system; the closest it can come to Earth is about 4 billion miles.

RIS倒是真实存在的，但它也只是一颗在太阳系外围活动的，类似于冥王星这样的矮行星。它与地球的最近距离也在40亿英里左右。

It is just weeks since Pluto was redefined as a dwarf planet.

从冥王星被重定义为矮行星之后仅仅几周。

This dwarf planet is further form the Sun than Pluto.

这个矮行星要比冥王星还要远离太阳。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
