The gas tail is blown directly away from the sun by the solar wind.

气体彗尾被太阳风径直吹离太阳。

No matter which way the comet is traveling, this gas tail will be pointing away from the sun.

无论彗星行进的路线在哪里，气体彗尾永远背向太阳。

The dust streams away, but because the pressure isn't as intense as the solar wind is on the gas tail, the dust tail blows away more lazily, and tends to lag behind the comet in its orbit.

尘埃会流走，但由于这种压力不像太阳风对气体尾流的影响那么强烈，所以尘埃尾流移动得更缓慢一些，而且往往落在彗星轨道的后面。
