随着人类对宇宙的研究逐步深入,并发现了越来越多的绕日行星,很多人想知道我们的太阳系有多大的代表性。参与行星搜寻活动的天文学家们经常说,发现地球般的世界是指日可待的。但一项新研究显示,太阳系的结构可能实属罕见。一组天文学家观测了猎户座星云中疏散星团内的类日恒星, With the gradual deepening of the human study of the universe and the discovery of more and more planets around the Sun, many people want to know how representative our solar system is. Astronomers involved in planetary search often say that finding the earth-like world is just around the corner. But a new study shows that the structure of the solar system may be rare. A group of astronomers observed the sun-like stars in the open star cluster in the Orion Nebula.
