问题 单项选择题

阅读下面一段说明文,完成下列问题
什么是星云过去人们往往把天空中一切云雾状的天体都说成是星云。其实,离我们非常遥远的位于银河系以外的云雾状天体,并不是星云,而是与银河系类似的庞大的恒星系统。根据它们的外貌,人们有时也称其为河外星云,即银河系以外的星云。不过,实际上还是应当如实地把它们称为河外星系。河外星系的发现使我们知道,在天文学史上早期所发现的“星云”中,只有一部分是真正的星云。星云不但应当看起来是云雾状的,而且应当是真正由气体和尘埃组成的云雾状物质。这样的星云广泛地存在于银河系和河外星系之中。而我们现在所能看到的只局限于银河系的星云,即所谓银河星云。它的类型不同。形状不一,大小不等。其中有一种叫弥漫星云,具有不规则的形状,一般没有明确的边界。我们的太阳系就是在弥漫星云中形成的。但是,直接形成太阳系的,并不是整个的弥漫星云,而是由弥漫星云分解而成的星云块,即所谓球状体。形成太阳系的那个球状体,我们称它为太阳星云。

将下列概念按其范围从大到小排列正确的一项是:
①太阳星云 ②太阳系
③天文学史上早期发现的星云 ④弥漫星云
⑤银河星云 ⑥星云
