13 Δεκ 2023 · The hottest part of the Sun is the core: 15 million K; ~15 million °C; 27 million °F. The coolest part of the Sun is the visible surface or photosphere: 4,000 – 6,500 K; ~5,500 °C; ~10,000 °F. Surprisingly, the solar atmosphere or corona is hotter than the Sun’s surface.
11 Μαΐ 2023 · The temperature of the sun varies from around 27 million degrees Fahrenheit (15 million degrees Celsius) at the core to only about 10,000 degrees F (5,500 degrees C) at the surface,...
17 Ιουλ 2021 · The average surface temperatures are at around 5.778 K, but they vary since it is composed out of three layers. Our Sun is an enormous energy and light-producing sphere of glowing gases. Though it is the hottest object in the solar system , other stars are far hotter, even tens of times so.
It is only about 500 km (300 miles) wide, a much thinner layer than the interior solar regions. The temperature of the photosphere is around 5,500 °C (9,900 °F), which is much cooler than the Sun's core. Most of the light energy produced in the Sun’s core escapes from the photosphere.
Sun Earth Ratio (Sun/Earth) Mass (10 24 kg) 1,988,400. 5.9722: 332,900. GM (x 10 6 km 3 /s 2 ... Surface Gas Pressure (top of photosphere): 0.868 mb Pressure at bottom of photosphere (optical depth = 1): 125 mb Effective temperature: 5772 K Temperature at top of photosphere: 4400 K Temperature at bottom of photosphere: 6600 K Temperature at top ...
The Sun is gradually becoming hotter in its core, hotter at the surface, larger in radius, and more luminous during its time on the main sequence: since the beginning of its main sequence life, it has expanded in radius by 15% and the surface has increased in temperature from 5,620 K (9,660 °F) to 5,772 K (9,930 °F), resulting in a 48% ...
3 Φεβ 2024 · Temperature: Around 5,500°C. Characteristics: The photosphere is the Sun’s visible surface, where light is emitted that we see from Earth. It’s marked by granules and sunspots, which are manifestations of the Sun’s magnetic activity.
