<p>I'm wondering if anyone could estimate the apparent size of the sun from different planets in the solar system, i.e., the sun appears 300% as large on Mercury as it does on Earth.&nbsp; I am especially curious about the relative size from Mars, Jupiter, and Saturn.</p><p>Thanks </p> <div class="Discussion_UserSignature"> </div>
