What are the distances from the sun of the five brightest stars on constellation Orion?

All the websites I found have distances from Earth, but I need distances from the sun.|||The closest of these stars, Bellatrix, is 240 lightYEARS away. The Earth and Sun are 8.3 lightMINUTES apart. And distances of stars are accurate to about 5 to 10%. So the difference in distance of the star from the Earth or the Sun is totally meaningless.


You need a good lesson in the meaning of significant digits.





Rigel: 773 ly


Betelgeuse 427 ly


Bellatrix 240 ly


Alnilam 1340


Alnitak 830 ly|||Bones is right. When you're talking about distances measured in hundreds of light years, you can consider them as given from the center of our solar system. Here is a very nice web page, providing lots of amazing details about the constellations, including Orion. Enjoy it!

Only two of the stars are close enough to have the distance measured by means of parallax:


Alpha Orionis, Betelgeuse: 430 ly


Gamma Ori, Bellatrix: 240 ly





The distances for the other stars are only estimated.|||well basically it is exactly the same distance. considering that a lightyear is a huge distance compared to an astronomical unit (distance from the earth to the sun). think about it this way, its like asking someone how far away is the celing to your head? its basically the same wether your talking about to your scalp or to your highest hair....its almost the same thing....so if your teacher is asking how far are the stars and the sites give you from the earth, well that means the sun too!!!! i hope this helps!!!!!!!|||The distance from the earth varies more than the distance from the sun (because we are circling the sun).
