ProximaCentauri 确实绕着两个明亮的邻居运行. Proxima Centauri really does orbit its two bright neighbours. 红色圆圈中央微弱的红色星星是ProximaCentauri 。 This planet circles a small red star called Proxima Centauri . 对于ProximaCentauri ,可能有轨道行星不到地球质量的一半。 For proxima centauri , there might be orbiting planets that are less than…. 这意味着发送到AlphaCentauri 的任何光都需要4。 That means that any light sent to Alpha Centauri will take 4.4 years to get there. 对于ProximaCentauri ,可能有轨道行星不到地球质量的一半。 For Proxima Centauri , there may be orbiting planets that are less than half of the Earth's mass.
奥米茄星团(OmegaCentauri )又名为NGC5139。 NGC 5139, also known as omega Centauri . 对于ProximaCentauri ,可能有轨道行星不到地球质量的一半。 For proxima centauri , there might be orbiting planets that are less than one-half of earth's mass. 双星AlphaCentauri AB也出现在行星和Proxima本身之间的图像中。 The double star Alpha Centauri AB also appears in the image between Proxima and the planet. 我将选择AlphaCentauri ,一颗离地球约4.4光年的恒星。 I will pick Alpha Centauri , a star that's about 4.4 light years from Earth. 频繁燃烧的ProximaCentauri 对其岩石行星来说意味着坏消息. Frequent flaring of Proxima Centauri means bad news for its rocky planet. 相比之下,距离太阳最近的恒星ProximaCentauri 距离267,000AU。 In comparison, Proxima Centauri , the closest star other than the Sun, is 267,000 AU distant. 比邻星和alphaCentauri a,b这对双星系统构成三合星。 Alpha Centauri A and Alpha Centauri B. These two are a binary star. 这张照片在10秒内将ProximaCentauri 的亮度提高了1,000倍。 The flare increased Proxima Centauri 's brightness by 1,000 times over 10 seconds. 这意味着发送到AlphaCentauri 的任何光都需要4。 This means that light from Proxima Centauri takes 4. Civilization与AlphaCentauri 虽然设置在不同星球,但是机制却大体一样。 Civilization and Alpha Centauri are set on completely different planets, but the mechanics are largely the same. 双星AlphaCentauri AB也出现在行星和Proxima本身之间的图像中。 The double star Alpha Centauri AB appears in the image between the exoplanet and its star. 下一篇:向地球上最近的系外行星邻居问好:ProximaCentauri b.
