Black Relationship Book Cover Ideas with Stars Symbols Lines Sun Earth Calendar Stardust Cosmic Orbit Years

The cover is predominantly black, with a minimalist celestial design. A golden circular representation of the sun sits in the center, surrounded by orbit-like thin white lines symbolizing Earth's rotations and revolutions. The lines shimmer subtly to evoke the cosmic relationship. Above the sun, the 24 divisions of the year are marked in minimal golden symbols forming a subtle arc. Below the sun, the years "1990-2200" are faintly inscribed in silver, with the texture resembling stardust. Tiny star-like specks spread across the black background for added depth.

The book title, "절기력 1990-2200," appears at the top in a clean yet elegant sans-serif font (e.g., Noto Sans Korean) in white, slightly offset from the center to balance the celestial design below. The author's name, "하나와열," is positioned at the bottom in a matching font but smaller, in golden text.

Title at the top center; central celestial design occupies the majority of the cover; subtle year placement below the design. The author’s name balances the lower portion of the cover. A polished golden border frames the entire composition without overpowering the design.
