no
Iron has nothing to do with it. A planet cannot explode - unless something massive hits it.
Never.
No. Planets cannot explode.
Because of quantum mechanics, anything is possible. However, it is very, very, VERY unlikely that any planet will explode.
Never. Period.
A planet cannot explode on it's own. A star would experience very little changes if a planet did explode, even one as large as Jupiter.
No it will not
We don't know. That's like asking if the Earth will ever blow up. More likely, in a few billion years when the Sun runs out of fuel and starts to become a red giant, Venus will be consumed, along with Mercury, Earth, and Mars.
If a dwarf star crashed into a planet,the planet would likely explode.
No.
It is unlikely for a planet to be entirely made of explosive compounds, as most celestial bodies consist of a variety of elements and minerals. However, in theory, a planet with a high concentration of reactive and unstable compounds could potentially have explosive properties under certain conditions.
Uhm, no
