猎户支臂
天文学家现在仍然认为我们的太阳位于离银河系边缘三分之一的位置,在一个称为猎户支臂 (Orion spur)的小旋臂上。
It is located 3, 800 light-years away from Earth, inside the Orion spur — the same partial spiral arm of the Milky way where our solar system is located. The nebula is nearly 240 light-years across.
它跨度近240光年,位于猎户座旋臂里,离地球3,800光年远;而我们的太阳系也在银河系同样的旋臂中。
Menkhib and the California Nebula are about 1,800 light-years away from Earth and are located within the same spur of the Orion spiral arm of the Milky way galaxy as Earth.
Menkhib和加州星云大约距离地球1800光年,并在对银河系的地球银河系猎户座旋臂位于同一方向。
