Circumtriple planet

<h2 id="fiction">Fiction</h2>
A circumtriple planet is prominently featured in the <a href="/facts/Remembrance_of_Earth%2527s_Past/8RB7PyWf">Remembrance of Earth's Past</a> book series. In the series, the planet of Trisolaris orbits a three-star system, and the chaotic nature of the system drives the native species of the planet to seek refuge on Earth, which has a comparatively more "stable" one-star system.<a class="footnote-ref" id="fnref:14" href="#fn:14">14</a>
