   2 days ago · The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.

   What is the hottest part of the Sun?

   • And the Sun’s core is the hottest part of all, at a sizzling 27 million degrees Fahrenheit! Our Sun is about 100 times wider than Earth, but it is just an average sized star. Astronomers have found some stars that are 100 times bigger than the Sun and others that are 10 times smaller. The Sun is also right in the middle of its lifecycle.

   What is the mass of the Sun?

   • The mass of the Sun, M☉, is 743 times the total mass of all the planets in the solar system and 330,000 times that of Earth. All the interesting planetary and interplanetary gravitational phenomena are negligible effects in comparison to the force exerted by the Sun.

   What is the convection zone of the Sun?

   • The Sun's convection zone extends from 0.7 solar radii (500,000 km) to near the surface. In this layer, the solar plasma is not dense or hot enough to transfer the heat energy of the interior outward via radiation.

   Is science committed to the fireball philosophy of the Sun?

   • As these expressions of scientific opinion are strictly in accordance with the sentiment of scientific bodies, both at home and abroad, they must stand as statements of current scientific opinion on this subject. Science is thus fully committed to the so-called fireball philosophy of the sun.

   3 days ago · While the temperature of the Sun drops from 15,000,000 K at the centre to 5,800 K at the photosphere, a surprising reversal occurs above that point; the temperature drops to a minimum of 4,000 K, then begins to rise in the chromosphere, a layer about 7,000 kilometres high at a temperature of 8,000 K.

    Sep 17, 2024 · Image credit: NASA/SDO/AIA. Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. The temperature of a sunspot is still very hot though—around 6,500 degrees Fahrenheit! Why are sunspots relatively cool?
