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,...
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% ...
13 Δεκ 2023 · Photosphere. The photosphere is the visible surface of the Sun. Temperature: Roughly 5,500 K. In Celsius: About 5,300 °C (usually rounded up to 5.500 °C) In Fahrenheit: Approximately 9,500 °F (usually rounded up to 10,000 °F)
The hottest part of the Sun is its core, where temperatures top 27 million °F (15 million °C). The part of the Sun we call its surface – the photosphere – is a relatively cool 10,000 °F (5,500 °C). In one of the Sun’s biggest mysteries, the Sun’s outer atmosphere, the corona, gets hotter the farther it stretches from the surface.
Students record the temperature of differently angled surfaces over set periods of time and calculate the temperature change to figure out how different parts of Earth are heated unevenly because of Earth’s shape and position in the solar system relative to the sun.
The surface of the sun, called the photosphere, is at a temperature of about 6000K and closely approximates a blackbody (see graph). For simplicity, the 6000 K spectrum is commonly used in detailed balance calculations but temperatures of 5762 ± 50 K 2 and 5730 ± 90 K 3 have also been proposed as a more accurate fit to the sun's spectrum.
