solar system.
solar = sun
The word solar and the prefix helio- pertain to the sun.
Within the Sun, nuclear fusion between hydrogen and helium takes place, giving off enormous amounts of energy. This energy is released in the form of radiation, which travels through the vacuum of space and reaches planets.
The planets orbit the Sun. The Sun is at the center of our solar system and does not move.
The planets travel around the sun.
In one word 'YES'. The paths that you describe are the planets orbits. These orbits are shaped like 'Ellipsoids'., that is an ellipse that doesn't quite close-up , but overloops with every circuit. The Sun lies not at the centre of the ellipsoid, but at one of the foci. As a consequence planets following their orbits paths speed up (Nearest the Sun) and slow down (Furthest from the Sun).

The adjective used to describe a noun as of or related to the sun is solar.
The term `gas giant` is used to describe a type of planet in itself, large planets further out from the sun that are mainly made from hydrogen and helium.
Aphelion is a word used to describe the furthest that a planet gets from the sun during it's orbit, while perihelion is used to describe the closest that it gets.

The word "sun" is not usually capitalized in a sentence. The exception is if it is used in context with other planets that are being capitalized in the sentence. Ex: "Jupiter is closer to the Sun than Neptune."
Many planets, mini-planets, asteroids, comets, and meteoroids circling around the sun.

The sun is made up of 74% hydrogen and 24% helium. It is also the center of the universe and the planets orbit around it. Those planets include terrestrial planets and gaseous planets. Terrestrial planets are Mercury, Venus, Earth, and Mars. They are also the planets closest to the sun. Gaseous planets, or "Gas Giants" include Jupiter, Saturn, Uranus, and Neptune.
