Create an illustration of the solar system in a flat design style

Create an illustration of the solar system in a flat design style. Place the sun in the center, with each of the eight planets orbiting around it. Use simple, flat colors for each planet and the sun, avoiding complex details. The background should be a deep blue to represent space. Show each planet with a distinct color and size, reflecting their differences. Include thin, simple orbit lines for each planet, arranged in their correct order from the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Near Earth, add the Moon as a small grey circle, orbiting around it.
