The sun!
:-P
From a great distance, our Sun, probably cannot be seen. It is a smaller star in our universe.
I think you mean the distance from the Earth to the Sun. This distance is measured in Astronomical Units (AU)
star
The nearest distance is called the perihelion and the furthest distance is called the aphelion (there is about 5 million km difference). The mean distance is called one astronomical unit.
perihelion
That's called its 'perigee'.
Louis te 14 called himself The Great Sun King.
There is no planet called Jupisaturn.
Aphelion.
The average distance from the Sun to the Earth is one "astronomical unit" or "AU".
The point in earth's orbit where it is closest to the sun is called "perihelion".
A sun seen from a great distance appears as a bright point of light in the sky, much like a star. Its size and brightness would diminish as the distance increases, but it would still stand out due to its luminosity, even at a great distance.
