If the SUN of our planet was the same size and proximity of the moon, would it still work as usual?

I'm building the world of my story for my comics and I've come to a bit of a standstill with a particular idea.

Assuming there were no other planets in our universe, just a single planet Earth.

1. The Sun is as the same size as the Moon (maybe slightly bigger).

2. The Sun has the same proximity the Moon currently has.

3. This planet in question still has a moon that does the usual orbiting

Would the SUN be able to:

• Provide the same heat, light and energy necessary for living organisms (humans, plants, animals, etc) to survive and carry out the usual life processes?

EDIT: I'm asking if the Heat and Light energy emitter with the size and proximity of the Moon could allow the planet to support life (If this planet in question was the only one in that universe.)
