Q & A - Where is the Edge of the Solar System?

<p class="p1"><strong>Written & hosted by our Program Director, Avivah Yamani.</strong></p> <p class="p1">Where is the edge of our Solar System? Or better yet, let's say where is the outermost boundary of the Solar System?</p> <p class="p2"> </p> <p class="p1">If it’s a town or a country, then even though we can’t really see the edge of it, we do know where the border is. </p> <p class="p2"> </p> <p class="p1">But in the Solar System, we need to define the boundary. So the solar system extends as far as the influence of the Sun. That could mean the influence of the Sun's light, or the influence of the Sun's gravity, or the influence of the Sun's magnetic field and solar wind.</p> <p class="p2"> </p> <p class="p1">We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.<span class="Apple-converted-space"> </span></p> <p class="p1">Just visit: <a href= "https://www.patreon.com/365DaysOfAstronomy">https://www.patreon.com/365DaysOfAstronomy</a> and donate as much as you can!</p> <p class="p1">Share the podcast with your friends and send the Patreon link to them too!<span class= "Apple-converted-space"> </span></p> <p class="p1">Every bit helps!
