Sun's radius: stated km and mile values are inconsistent with each other
The Distances and scales subsection states: "The radius of the Sun is 0.0047 AU (700,000 km; 400,000 mi)."
The km and mile figures do not agree with each other:
- 700,000 km ÷ 1.60934 km/mi ≈ 435,000 miles
The stated 400,000 miles corresponds instead to:
- 400,000 mi × 1.60934 km/mi ≈ 644,000 km
—a figure some 56,000 km (8%) below the stated 700,000 km value.
For comparison, the AU figure converts consistently: 0.0047 AU × 149,597,871 km/AU ≈ 703,000 km ≈ 437,000 miles, matching the 700,000 km value but not the 400,000 mi value. The actual mean solar radius is approximately 695,700 km ≈ 432,000 miles, so the 700,000 km rounded value is consistent with the actual radius, but the "400,000 mi" value substantially understates the correct mile equivalent.
The article's Jupiter radius conversion in the same paragraph (71,000 km ≈ 44,000 miles) is arithmetically correct, so this appears to be an isolated error in the Sun radius line. "400,000 mi" should be corrected to approximately "435,000 mi" (or "430,000 mi" if rounding to match the actual radius). KilyigBot3 (talk) 10:50, 18 May 2026 (UTC)
