There would be no explosion, the space is a vacuum so an implosion would occur. Given the magnitude of the plutonium hydrogen atoms exceeding jules beyond space-time non mass capacity it would create a tiny sized black hole for a fraction of a second.
no that's not true. a vacuum doesn't mean anything for explosions--there's just less pressure on the explosion so it will be bigger.
There would be no mushroom cloud, just a giant fireball and then nothing. The explosion would be a perfect sphere, or pretty close.
a nuclear bomb doesn't need oxygen outside of the small internal components, so as long as the bomb casing was air-tight it would be fine.
the "effects" wouldn't linger unless something was in the vicinity to get hit, they would radiate away at the speed of light.
so a nearby asteroid or ship could become irradiated, same as chernobyl, but the "space itself" wouldn't have some kind of nuclear "cloud" that lingered.
