I don't know. I mean, even if you went "at night" -- aka directly away from the Sun, always keeping the Earth in between -- you'd never get near the Sun. Unless you set out to circumnavigate the Universe. And in any case, once you got farther than the Moon's orbit, it wouldn't be night anymore, because you'd see the Sun.
So OK, approach the Sun edge-on. So is this a riff on flat-Earthers? I suppose that they might also have the Sun being flat. I can't quite imagine the geometry.
