I'm just having trouble deciding which one it might be. <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f609.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=";)" title="Wink    ;)"  data-smilie="2"data-shortname=";)" />But with the distances involved it hardly matters.The closest star is Proxima Centauri at 4.2 lightyears. That's about 40 trillion kilometers.The closest detected exoplanet (planet orbiting a star other than Sol) orbits Epsilon Eridani, which is 10.5 lightyears away (63 trillion miles). Most of the others (that we've detected) are within 300 lightyears of us.What's 60 million lightyears away? the spiral galaxy called Messier 90.The fastest theoretically viable stardrive at the moment seems to be nuclear pulse propulsion (correct me if you find something faster, please). The Project Orion. It would get you to Proxima Centauri in 85 years. If you used the Ion drive we now have working, 8000 years. Yeah.Edit: sorry, now I made an error: the ion drive would get you to Proxima Centauri in 80000 years.</blockquote>
