Inner Solar System Orbit Diagram

A precise educational diagram of the inner solar system, top-down view, as a clean infographic poster. The Sun sits slightly off-center to the left, a glowing amber disk with a soft corona halo. Four concentric elliptical orbits radiate outward as thin dashed white lines, each carrying a labeled planet: Mercury as a small grey sphere, Venus as cream-yellow with a thin atmospheric ring, Earth as a blue-and-white marble with a tiny grey Moon, and Mars as a rust-red sphere. Each orbit is annotated in plain sans-serif: "Mercury — 0.39 AU", "Venus — 0.72 AU", "Earth — 1.00 AU", "Mars — 1.52 AU". Bottom-right corner holds a compact legend titled "Inner Solar System — Orbital Distances (not to scale)". A faint dotted asteroid belt curves at the outer edge. Background is deep navy with very subtle star noise. Color palette: deep navy, amber sun, cream, ocean blue, rust red, off-white type. Mood: scientific, clear, calm. No fantasy elements, no constellations.

一张精确的教育示意图：内太阳系俯视图，干净的信息图海报风格。太阳略偏左，琥珀色发光圆盘带柔和日冕。四条同心椭圆轨道用白色虚线向外扩散，每条轨道上标注一颗行星：水星灰色小球，金星奶黄带细大气环，地球蓝白珠配灰色小月亮，火星锈红球。每轨标注名称与平均距离：「Mercury — 0.39 AU」、「Venus — 0.72 AU」、「Earth — 1.00 AU」、「Mars — 1.52 AU」。右下角紧凑图例 "Inner Solar System — Orbital Distances (not to scale)"。外缘有淡虚线小行星带。背景深海军蓝，极轻微星噪。色板：深海军蓝、琥珀、奶白、海洋蓝、锈红、米白文字。氛围科学、清晰、冷静。不要奇幻元素或星座。
