Scientists believe that the sun was formed from a gas and dust cloud called the solar nebula, which was part of a giant molecular cloud. The supernova theory suggests that shockwaves from a nearby supernova triggered the collapse of the solar nebula, leading to the formation of the sun and the solar system. Isotopic analysis of meteorites and the sun's composition support this theory.
Iron is not formed in the Sun through nuclear fusion. Iron is the element with the highest nuclear binding energy per nucleon, making it less energetically favorable for fusion reactions to produce iron in the Sun. Iron is typically formed in the later stages of a massive star's life during a supernova explosion.
Uranium is not directly produced by the sun. Uranium is formed through the process of supernova nucleosynthesis during the explosion of massive stars. Elements like uranium are created during supernova explosions, where the intense heat and pressure fusion lighter elements into heavier ones.
Most of the planets probably formed within a million or so years of the time the Sun formed. That sounds like a long time, but for an astronomer that's a pretty short period. Looking further out, it's entirely possible that several nearby stars were formed about the same time as our solar system. Some theories of stellar formation suggest that a stable nebula of gas and dust is unlikely to coalesce without some external impetus, such as the shock wave from a "nearby" supernova. And we know that our solar system was formed from matter blown into space by probably several previous supernova explosions. (Otherwise, there would be no heavy elements such as lead, gold, or uranium - elements only created in supernova explosions! - on the Earth.)
The sun is not big enough to supernova. It's not even big enough to nova. The fate of the sun is a Red giant, a white dwarf then a black dwarf. Therefore we don't need to worry about the sun becoming a supernova. We need to worry about the sun expand to the size where it touches Jupiter.
Iron is the heaviest element formed by fusion in the core of a supergiant star prior to its supernova explosion. Elements heavier than iron are typically formed during the supernova explosion itself through nucleosynthesis processes.

Never. A star must be about 10 times the mass of the sun or more to go supernova.
It's formed in supernova explosions.
Uranium is not directly produced by the sun. Uranium is formed through the process of supernova nucleosynthesis during the explosion of massive stars. Elements like uranium are created during supernova explosions, where the intense heat and pressure fusion lighter elements into heavier ones.
The Sun won't go supernova (it isn't massive enough) so the question has no real answer!
Prepositional phrases that begin with after are adverb phrases: e.g. "The nebula formed after a supernova" meaning the nebula formed afterward.
It is postulated that a supernova explosion was the catalyst which formed our Solar System.
White Dwarf, Sun, Red Giant, Supernova
Oh, sure. The Sun is a Supernova. That's why we're all sitting here burning to death.
