A white dwarf
It's not known for certain, but it will engulf Mercury and Venus and it's outer envelope will be very close to Earths orbit.
Technically the explosion of a Red giant is not called a Supernova as the mass of the star is not great enough. However the explosion from a Red Super Giant can be called a supernova. A normal Red giant doesn't actually explode, the core just collapses again to cause a white dwarf and the outer layers are ejected to form planetary Nebulae.
The explosion of a red giant is called a supernova. It would be quite spectacular to watch! I hope this answer helps :D Technically the explosion of a Red giant is not called a Supernova as the mass of the star is not great enough.

Right after the red giant has thrown off it's outer envelope, revealing a hot and very luminous white dwarf.

Typically it is called a planetary nebula. It has nothing to do with planets.

A planetary nebula consists of gas ejected from old red giant stars.
The Sun will not explode.In about 4.5 billion years, our Sun will slowly cool and turn into a red giant, it's outer envelope will almost touch the Earth.After about another million years, it will shed it's outer envelope, causing a planetary nebula What is left of our Sun, is a white dwarf about the size of the Earth, which will slowly radiate it's remaining heat into space for billion and billions of years.
