File:Castor stellar system zoomed in 40x.png

English: An image of a Castor sextuple star system captured in Space Engine. The image was zoomed in by 40x. In this image, every binary star system are named but they're not clearly seen because they're too close to each other. In this image, the two bright white lights are came from two A-type Main sequence stars (Aa and Ba). In A and B binary, there are two red main sequence stars (can only be seen via images of their stars, because they are blinded by their much brighter white stars). The orange light come from two red main sequence stars (Castor C binary). In addition, I've also expressed individual stars (but the images of expression are different). Note: This is the second version. The first version only showed three binary stars in appearance, because their stars are too close to each other.
