27,845,775 AU. The first source says they are 135 parsecs away and the second source says a parsec is 206,265 AU. I just did the multiplication. Call it a nice round 28 million, because I am sure not all those digits are significant.

Approximately:

130 Parsecs = 425 Lightyears = 93000000 AUs

I used the following:

186000 (miles light travels per sec)

5869713600000 (distance in miles light travels per year)

63115.2 (astronomical units light travels per year or (miles light travels per year divided by 93 million miles (distance of one AU)))
