Paul Wiegert says that two more asteroids in earth-resonant orbit have been found, 1998 UP1 and 2000 PH5.保罗维格特说，两个轨道的小行星在地球谐振被发现，1998年和2000年找到补偿其余PH5。 (If I find position-velocity XYZ coordinates for those and the inner planets at some point in time, I'll put up applets of those too.) （如果我找到的位置，速度某某时间的一些坐标点，并在内部行星，我要是把那些太的小程序。）
| First, the normal view of solar system.首先，太阳能系统的正常看法。 Cruithne is the purple ellipse. Cruithne是紫色的椭圆。 Earth is the blue circle.地球是蓝色的圆圈。 This simulation includes all the planet, but doesn't handle relativity, and the earth/moon system are lumped into one point.该仿真包括所有行星，但不处理相关性，和地球/月球系统的集中到一个点。
You can use the mouse to start and stop the image, and to move the view point (by dragging).你可以使用鼠标来启动和停止该图像，移动点（通过拖动视图）。 | |
| Next, the most informative view my applet can manage, a strobe version drawn once per Earth year.下一步，我认为最翔实小程序可以管理，闪光灯版本绘制年一次，每次地球。 Since every year Earth comes back to the same point in its orbit, and this is drawn once per year, Earth appears to stay fixed.由于地球每年回来的同一点在它的轨道，这是一年一次，每次绘制，地球似乎留固定。 Cruithne also has an orbit of almost one year, that's why consecutive purple dots are close to one another. Cruithne也有近1年的轨道，这也是为什么连续紫色点彼此接近。
Cruithne has an orbit slightly less than a year at first, then when it approaches Earth it slows down to slightly more than a year, and back and forth and back and forth. Cruithne有轻微第一轨道一年不到，那么当它接近地球它减慢至略超过一年，并来回及来回。 The little wobbles in Cruithne's orbit are apparently due to Jupiter. Cruithne的轨道小震荡中显然是由于木星。 I didn't include any planets beyond Jupiter, for speed.我没有任何行星包括木星之外，速度。 | |
| Strobe version again.频闪版本再次。 Side view.侧视图。 Earth remains a blue dot.地球仍是一个蓝色的圆点。 Note that Cruithne is pretty far out of the main plane of the solar system.请注意，Cruithne是相当遥远的太阳系主要平面的。 All the planets are included.所有行星都包括在内。 You can drag the image if you want to try different viewpoints.你可以拖动图像，如果你想尝试不同的观点。
The numbers in the upper lefthand corner are number of years, and energy difference from the start of the simulation.左角落上的数字是在数年内，能源仿真差异从一开始的。 (Ideally energy is conserved, but my simulator isn't perfect.) Official estimates say Cruithne should leave this orbit in around 5000 years. （理想的能量是守恒的，但我的模拟器是不完美的。）官方估计说Cruithne应该离开这个轨道在5000年左右。 This simulation says it stays in about the same orbit, but resonance gets spotty around 5000 years and goes away entirely around 10000.该仿真说，停留在大约同一运行轨道，但共振得到参差不齐大约5000年左右完全离开去10000。 | |
| Here's the same thing again, but with coordinates supplied by Paul Weigert, who is studying the orbit of Cruithne.下面是同样的事情了，但提供的坐标与Cruithne保罗韦格特，谁是学习的轨道。 Are this simulation and the previous one noticably different (other than having slightly different viewpoints)?这是一个模拟与以前的情况显着不同（除有稍微不同的观点）？
I'm not accounting for relativity.我不是会计的相关性。 My simulation says the oscillation takes about 760 years.我说，振荡模拟需要约760年。 The official estimate is 770 years.官方的估计是770年。 Is that due to relativity or a bug in my simulator?相对论是，由于在我的模拟器或错误？ | |

This is the perspective from Earth, actually where all the object appear in the sky.这是从地球的角度来看，其实，所有的物体出现在天空。 The one on screen all the time is Pluto.在屏幕上一时间所有的冥王星。 The purple one is Cruithne.紫色一个是Cruithne。 This isn't very informative, although it does give you a chance to see Mars do its retrograde orbit thingy.这是不是很丰富，但它确实给你一个机会看到火星尽其物质的逆行轨道。 It would be more interesting for Cruithne if I could put the eye on earth, like this, plus keep the sun at a fixed point in the sky.这将是更Cruithne有趣，如果我可以把地球上的眼睛，这样，加上天上的太阳保持在一个固定点。 I can't do that yet.我不能这样做呢。 | |
| Finally, the normal view again, no strobe, no trails.最后，再普通视图，无频闪，无小径。 Everything beyond Jupiter was removed for speed.一切都超出木星被删除的速度。 Planets are drawn bigger than they really are.绘制行星大于他们真的是。 |

Cruithne是什么词啊，没间过，查不到
环绕地球当然有影响了，但是不是佷大，有些航天员在太空一个多月。
