The exoplanet hunting Kepler mission’s total for candidate and confirmed multiple planet systems stands at 1,705 worlds in orbit around 685 distant stars. Put all of those exoplanet orbits on the same scale and follow their relative orbital motions to get Kepler Orrery IV. To make the planets visible, their sizes aren’t shown to scale. But orbits of the planets in the Solar System (dashed lines) are included to scale in the hypnotic video. Of course, Kepler uses planetary transits to detect exoplanets, looking for a slight dimming of light as the planet crosses in front of its star. In the time compressed video, Kepler’s multiplanet system orbits are all oriented to put observed transits at the three o’clock position. The dervish-like movements highlight a stark contrast between most Kepler-discovered exoplanetary systems and our own. Planning an interstellar vacation? Be sure to check the scale at the upper left first. The color code indicates a planet’s estimated equilibrium surface temperature based on its orbit size and parent star.

🌌 來自Kepler任務的最新發現！目前，共有1,705顆候選行星和確認的多行星系統，圍繞著685顆遙遠的恆星運行。✨ 在Kepler Orrery IV的動態視頻中，所有外行星的軌道都被放置在相同的比例上，展示了它們的相對運動。
雖然行星的大小沒有按比例顯示，但視頻中包含太陽系行星的軌道（虛線）卻是按比例顯示的。🌍🎥 為了觀察到行星的過境，Kepler通過測量星光在行星穿過前方時的微弱變暗來檢測外行星。在這段時間壓縮的視頻中，Kepler的多行星系統的軌道都被調整到三點鐘方向，以便觀察到的過境。
這些旋轉的運動展現了Kepler發現的外行星系統與我們的太陽系之間的鮮明對比。計劃一次星際假期前，別忘了查看左上角的比例標尺！🌠🌌
📏 色彩編碼顯示了根據行星的軌道大小及其母恆星估算的平衡表面溫度。 ☀️
