Of course "Hayabusa" is not actually closing in on the Sun, it is just positioned as in the figure so that, seen from the Earth, it is on the opposite side of the Sun; this is called 'conjunction'.
The sun is shining.
The sun is about to rise.
The sun is about to set.
If you watch the sun setting on a warm, damp day, you can see the moisture changing the shape of the sun.
If it were not for the sun, we could not live at all.
