V772 Herculis is a Quintuple star system, and one star is particular sun like so I can plonk the Porygon planetary system thereIncidentally, the primary of V772 Herculis is an eclipsing variable of G and K type dwarfs, a 21 hour cycle of two eclipses by the cooler star should fuck up a habitable planet too much, right? <a href="https://mastodon.social/tags/Worldbuilding" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Worldbuilding</a> <a href="https://mastodon.social/tags/Exoplanets" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Exoplanets</a> <a href="https://mastodon.social/tags/Astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Astronomy</a> <a href="https://mastodon.social/tags/Exobiology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Exobiology</a>
