After writing [this question][1], I came up with a new question.

#Consideration
1. The considerations are mostly similar to the linked question (reading it is highly encouraged, as I am trying to post as little redundancy as possible)
2. The ship in question is comparable to Apollo 11 lunar module
3. The distance from the star is roughly the distance between Earth and the Sun

#The Questions

1. How long would an antimatter ship (not powered by antimatter, but *composed of antimatter*) survive with exposure to stellar winds?
2. How much energy is released during the exposure?
3. How long could the crew (consider human-like physiology and radiation resistance) survive the radiation before dying?
4. Related to number 2, would the radiation affect the planet or life on that planet in a way that's not negligible in effect? Consider the minimum unshielded distance from the planet's center to be around 1.2 times the radius of Earth, and away toward the moon.
