New Horizon's distance from Pluto drops below 500 million km today. The main thread here has been active since before launch and until today.
Today is an appropriate day for a new thread and there are also less than 14 months until Pluto arrival (time flies!). The coming months will see more spacecraft activity than in recent years with optical navigation images of Pluto/Charon, images of Neptune etc. The next 14 months are going to be interesting to say the least. |

A good way to simulate the brightness of the sun at pluto imho is when a solar eclipse at earth comes close to the totality phase.
I think about 15 to 10 minutes before totality arrives is just about the same brightness level at pluto..but this is only rough guess and depends on the eclipse geometry. Could one do the math for this please ? Shadows during this eclipse phase on earth are strange because of the thin sun sickle..shadows at pluto must be still more sharper with almost no penumbra visible. Robert |
