As far as I know, the sun is always the center of a solar system unless there is something with a greater mass very close by. I believe it would just be called a solar system.
2nd Answer:
Good answer! It also could be called a 'heliocentric' model. Heliocentric means, "Sun at the center".
Because the center of the raibow you see is on the line from the sun through your head. When the sun is low, the center of the rainbow is high, and you see more of it. When the sun is high, the center of the rainbow is low, and you see less of it.
-- Just like each planet, and probably every star, the sun is spinning. -- Every point on the surface moves in a circle, and the center of every circle is inside the sun. -- All of those points together make a line inside the sun ... the line that the whole sun spins around. -- The points where the ends of that line stick through the surface are the poles of rotation. Even easier: -- Take a big apple. -- Stick a sharp pencil through the whole apple and right through its center, so that you can grab the ends of the pencil and spin the apple. -- The two places where the pencil sticks through the apple skin are the poles of the spinning.
The Sun is at the center of the Solar System. the SUN is the centre of our solar system.
The Sun is the star at the center of our solar system. It is a massive ball of hydrogen and helium that generates light and heat through nuclear fusion. The Sun's gravity holds the solar system together and provides the energy necessary for life on Earth.
When the moon is directly in line with the sun, it is called a "new moon." This is the phase where the moon is not visible from Earth because it is positioned between the Earth and the sun.
The Sun's center, or core.

The imaginary line drawn through the center of the Earth around which Earth rotates is called the axis. This axis is tilted at an angle of approximately 23.5 degrees relative to the plane of Earth's orbit around the Sun, which causes the changing of seasons.
The Sun's core.
The center of the moon must be pretty close to being on the line through the center of the sun and the center of the Earth, which places the moon in Earth's shadow.
There is no such thing. The Sun has a center, generally called its "core"; the center of an atom is called a "nucleus". The Sun has many, many atoms in its center, each with its nucleus.
When you see a rainbow, there is a direct straight line from the sun (in a clear sky), through your head, to the center of the rainbow (in water-droplet-filled air).

The particles that bring heat and light from the center of the sun to Earth are called photons. Photons are electromagnetic particles that carry energy and travel through space as part of sunlight.
It's called "the sun".
The center of the sun is called the core. :)
