中文翻譯:
你想去一個每年只有3.14天的星球嗎？那就計劃一下去K2-315b旅行吧！這是一顆和地球差不多大小的星球，圍繞著一顆冷冷的紅色M型矮星轉動，完成一圈只需要約3.14天。這顆外星球是在2020年被發現的，數據來自於公眾可以獲得的Kepler太空望遠鏡的延長K2任務。K2-315b的繞行時間和非常受歡迎的無理數圓周率Pi相等。因為它離父母星星非常近，所以它的表面可能非常熱，簡直是燒得通紅呢！而且這顆Pi星球距離地球有超過185光年。所以，與其安排一次到K2-315b的星際假期，不如想一些更簡單、更舒適的方式，來慶祝我們地球上的Pi日吧！
原文:
Want to visit a planet that has 3.14 days in a year? Then plan a trip to K2-315b, an earth-sized planet orbiting around a cool, red, M dwarf star about once every 3.14 days. The exoplanet’s discovery, based on publicly available data from the planet-hunting Kepler Space Telescope’s extended K2 mission, was announced in 2020. K2-315b’s measured orbital period in days is nearly equal to the extremely popular irrational number Pi. That puts the exoplanet so close to its parent star that its surface is likely very warm, baking-hot in fact. And this Pi planet is over 185 light-years away. So instead of trying to arrange for an interstellar vacation to K2-315b, there may be easier and more comfortable ways for you to celebrate Pi day on planet Earth.
