What is the Sun to other Planets?

Yes. It's late at night and my mind began to go. Not in the anxiety ridden speed it used to, caused by lack of sleep and excessive sugar consumption, but in my glossing over of information about the Sun for the Leo podcast episode. A thought came to me. 

I began to think: what is the Sun to the other planets? Often we call the Sun the giver of Life - there's Sun worship,  its signifier with the moon to represent time and cycles, its spiritual value, etc. It literally gives and sustains life on Earth.

But this appears to be from our one limited perspective and our experience of Life HERE - Earth. What is the Sun to Mercury, or Mars? What about Venus? What is the Sun to Neptune, Pluto? What is the Sun to Saturn and Uranus? What is its Value?

Yes, some of us heard that it is the Sun's magnetic field that keeps the planets in the Sun's orbit. But from the perspective of living in another planet - what "Value" does the Sun hold elsewhere? What would the life's mythology be for inhabitants of Mars for instance? 

What would the giver of life be to a planet that does not have the atmosphere to support the original giver of life?
