Ok so if we go at night, we would have to get there before daybreak. That gives us about 8 hours of dark.
But seriously Fahrenheit? 2700 Degrees Bullcrap = 1500 Celcius which is about the melting point of iron and 15 times the boiling point of water. What tempearature does bullcrap boil at? 1 Bullcrap = 17 Pidgeon droppings which is apparently very very very cold. I think.
Also, the sun surface is around 5500C (about 9940 Bullcraps, can you imagine that much crap? No me neither.) but the corona of the sun is one to three million C, so unless we invent deflector shields from star trek we can go near it. I like the 100miles comment. A 100 miles (160km) in terms of the sun is nothing. We won't be able to go closer than millions kilometers of the blerry thing.
