(The following is based on some quick calculations that I did, assuming the mass of the SBH is exactly 1 million times the mass of the Sun.)
Now suppose that this SBH happened to come into our galaxy, and in fact came close to our solar system. (Again, this is so improbable as to be hardly worth considering. But it's still fun to think about.) Once it started moving through the Galaxy, we would start to notice the orbits of stars that it encountered being disrupted. And in fact, our solar system's orbit around the center of the Galaxy would be disrupted if it came close. How close? I'm thinking that we would start to notice something was fishy if it came within about 1000 light years of our solar system. But the disruption of our solar system's orbit around the galactic center probably wouldn't have any catastrophic implications for life on Earth. In fact, even if we were on a "collision course" with the SBH, we would probably have a few hundred thousand years between the time we cross that ~1000 ly threshold and the time the *real* disaster begins.

(以下基于对我做了一些快速计算，假设美国 SBH 大量到底是 1 万倍的太阳质量.)现在假设这 SBH 碰巧走进我们的星系，事实上走近我们的太阳系。(再一次，这是不可能，几乎值得考虑。但它仍是想想很有趣)。一旦它开始移动通过银河系，我们将开始注意到它遇到被打乱了的恒星的轨道。事实上，我们的太阳系的轨道围绕银河系的中心会中断，如果它来关闭。如何关闭?我在想，我们会开始注意到什么事不对劲是否它来了在大约 1000年光年的太阳系内。但我们的太阳系的轨道绕银河系中心的中断大概就没任何灾难性的影响，为生活在地球上。事实上，即使我们在与美国 SBH"相撞"，我们可能会我们穿过那 ~ 1000 ly 阈值的时间和时间的几个 10 万年间 * 真实 * 灾难开始。

现在假设这个SBH碰巧进入了我们的银河系，而事实上接近我们的太阳系。（又一次，这是不可能的，因为很难不值得考虑。但它仍然是有趣的想法，一旦开始移动通过银河，我们会开始注意到恒星的运行轨道被破坏了。事实上，我们的太阳系围绕银河系中心的轨道将被破坏，如果它靠近。接近吗？我想我们会开始注意到一些可疑的东西，如果它出现在大约1000光年的太阳系里。但是我们的太阳系绕银河系中心的轨道的中断可能不会对地球上的生命产生任何灾难性的影响。事实上，即使我们在一个“碰撞”的SBH，我们可能有几百上千年的时间我们之间的交叉，~ 1000阈值和真正的灾难开始的时候。
