Its enought to encompass Earth I know, but how much further, Mars, Jupiter, Satun?

Zero.

The sun will neither go nova or supernova. The sun will just puff up to become a red giant. At its max it could very well gobble up Venus and its outer atmosphere will lick the scorched earth. But when the sun finally runs out of fuel its core will contract and its outer layers will gently drift of into space. The core will shrink to become a white dwarf about the size of earth. Earth might remain after all that but will have gone from a lush vibrant world to a burnt out cinder to a frozen lump of rock.
Only stars about 8 times as massive as the sun can go supernova. And novae are caused by matter accreted on the surface of a white dwarf in a binary star system.

As stated earlier our Sun does not have the mass or the chemical composition to go supernova, ie very large explosion. What our Sun will do is swell into a Red Giant type star.
Mercury and Venus will be eaten by the swelling sun but is it in debate whether the Earth will suffer the same fate in 4 to 5 billion years.
What we do know is when the starts the phase of becoming a Red Giant then all it will take is a planet wide temperature rise of 15 degrees to kill all life on the planet. Of course it will not happen over night but over the course of hundreds of years.

It won't even go nova, unless at some point in the coming billions of years, in the white dwarf stage, it goes into orbit with another star and starts gobbling up material from it. If that happens, it may cause an explosion every so often as it reaches a certain mass.
The sun will expand to a red giant (several times, actually), about the size of Venus or Earth's current orbits. It will then let go of it's outer layers and becoming a white dwarf.

The Sun is not expected to go supernova or nova. It is expected to become a red giant star in billions of years, but that is not a blast or explosion. And it could engulf Earth. Maybe Mars too, but probably not. Definitely not Jupiter.

The sun is too small to blow up.
Eventually it will expand and maybe reach out as far as earth's orbit and vaporize it, it'll be a while.

Our sun will go nova,not supernova,an entirely different phenomena.It is thought it will expand possibly out to mars,several times,before settling down as a "white dwarf"

Our sun does not have enough mass to become a supernova.

The mass of the sun is not large enough for it to go super nova.
