A vibrant, child-friendly, hand-drawn illustration of the solar system designed for a preschool science book cover. Includes cartoon-style planets with different textures, cute details like clouds on Earth, colorful rings on Saturn, and swirling patterns on Jupiter. The background is a dark purple galaxy with glowing stars, comets, and shooting stars. Everything is created with crayon or chalk-like textures. No text or letters in the image. The style is playful, educational, and imaginative, similar to a classroom poster.
