I'm writing a sci fi thriller and I'm including an inter-species romance scene which involves a pair of star crossed lover, a middle aged man and a mutated botfly no larger than a penny both drifting at a non-lethal distance away from the surface of Pistol Star, a blue hypergiant or V4647 Sgr after their interstellar spaceship got stranded in space during a daring exploration to the center of Milky Way galaxies.
Long story short, the mission ended in disaster and most of the crews as well as their pet companions were killed but that's not the main issue right now, I thought that the survivor and his fetish could somehow get into an outdated astronaut suit made from the 21st century A.D. due to an unforeseen circumstances before making their escape as the ship is about to explode, I just want to know how close can our main protagonist and his fiancee stay in orbit at a safe distance from the surface of the hypergiant apart from the lethal stellar wind before becoming crispy.
Let's assume that the Pistol Star is at least 100 solar mass, the human and the insect are sharing 1 spacesuit together and last but not least please provide your working to support your answer. Remember they should survive long enough to exchange their vows say between 10 to 30 minutes.
