I am curious about where our sun/planetary system fits into the universe. Is our sun a part of any known star system? By using astronomy software it appears we could be part of alpa centauri. Also is our sun a star in any known constellation? How would the earth appear to someone on venus or jupiter (I am thinking in terms of illumination/brightness)? Would our planet the earth be a morning or evening star if I were on Jupiter or Venus or any other planet? I am not an astronomer, but I can't to seem to find the answer to any of these questions. If anyone knows the answers to any or all, or could point me in the right direction to research this, I would appreciate it. Thanks.
