Question

It depends on how you measure. The sun puts out solar wind, which travels into the interstellar medium. At some point, it is slowed down to an effective stop. This is known as the heliopause. BUT, it is not spherical. The closest edge is approximately 

100 AU = 1.49598e10 km = 0.00158128588 lightyears

away from the sun. Pluto's farthest distance from the sun is 

49 Au = 7.330302e9 km 

so that can be considered a radius as well. 

It all depends on your definition. Be sure to say what measure you are using
