    Sep 22, 2022 · The temperature at the very center of the Sun is about 15,000,000° C (27,000,000° F) and the density is about 150 g/cm³ (approximately 10 times the density of gold, 19.3 g/cm³ or lead, 11.3 g/cm³). Both the temperature and the density decrease as one moves outward from the center of the Sun.

    Nov 16, 2023 · 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.
