Sistema solar infografia de estrellas de secuencia principal

Astronomy infographic titled "Main Sequence Stars in the Star Lifecycle" using a COMPARISON of cosmic scales archetype. Show a horizontal comparison lineup of representative main-sequence stars across spectral classes, arranged from smallest/coolest to largest/hottest, with a clear header label "Main Sequence Stars" and a visible note "not to scale" where size spacing or distances are simplified. Central diagram: scientifically reasonable star colors and relative proportions for M, K, G, F, A, B, O main-sequence stars, with glowing disks and subtle radius comparison guides; include a compact lifecycle context arrow showing "Protostar → Main Sequence → Giant / Supergiant → Remnant" with the main-sequence phase highlighted. Add 7 labeled callouts, each with canonical object or class name and one accurate fact in English: "Proxima Centauri — M5.5 V red dwarf; mass 0.122 Solar masses", "Barnard's Star — M4.0 V red dwarf; surface temperature about 3,130 K", "Alpha Centauri B — K1 V star; mass 0.91 Solar masses", "Sun — G2 V star; diameter 1,392,700 km", "Procyon A — F5 IV-V star; mass about 1.46 Solar masses", "Sirius A — A1 V star; surface temperature about 9,940 K", "Spica A — B1 III-IV / near-main-sequence massive star; mass about 10.3 Solar masses", "Sigma Orionis Aa1 — O9.5 V star; surface temperature about 35,000 K". For each object, mark name, a scale-aware size label such as relative radius versus the Sun, and one fact panel; use leader lines and small spectral-color chips. Add a small scale-reference strip in English: "Sun diameter = 1,392,700 km", "Earth diameter = 12,742 km", "1 Solar mass = 1.989 × 10^30 kg". Include a legend for spectral sequence with exact labels "M red", "K orange", "G yellow", "F yellow-white", "A white", "B blue-white", "O blue". Style: retro 1960s space age poster design, deep cosmic dark palette, muted navy, indigo, teal, amber, cream and soft neon cyan accents, halftone texture, fine orbit-grid motifs, clean iconographic annotation, high contrast for readability, editorial astronomy illustration, dark-mode-friendly cosmic palette, vector-clean infographic layout. Audience level: astrophysics enthusiast, so use precise stellar classifications and metrics. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no UFO / pseudoscience imagery, no watermarks Scientifically accurate facts, no UFO / pseudoscience imagery, no astrology framing. Sizes and distances are typically not to true scale — label as such.
