Q:

How hot is the surface of the sun?

A:

Quick Answer

The temperature at the sun's surface is approximately 10,000 degrees Fahrenheit. Moving towards the core of the sun, the temperature increases significantly to about 27,000,000 degrees Fahrenheit. Pressure at the core is also extremely high.

Nuclear fission occurs in the sun's core, where the compression of hydrogen atoms produces helium. Large amounts of energy are created during this process, which radiates outwards towards the surface and beyond.

The sun's heat generates from the solar surface outwards towards a section of the solar atmosphere called the corona. The temperature in the corona can reach as high as 3.5 million degrees Fahrenheit. The corona is the topmost layer of the solar atmosphere, which is visible as a halo during a total solar eclipse.

  • Q:

    Why does the sun shine?

    A:

    Stars, including the sun, derive their energy from the process of nuclear fusion taking place in their cores which causes a release of light at the surface. This process converts matter into energy and releases vast quantities of neutrinos and gamma rays. The sun has a core of about 27 million degree Fahrenheit.

  • Q:

    Where does the sun rise and set?

    A:

    The sun actually does not rise or set; it is only perceived as rising or setting because of a person's vantage point on the surface of the Earth. This perception of the sun rising and setting is due to the rotation of the Earth itself.

  • Q:

    What is a granule on the sun?

    A:

    A granule is a cellular feature found on the surface of the sun that is caused by convection currents. Granules are situated atop convection cells, except in areas enveloped by sunspots, that release hot fluid from their interior. This process creates bright spots on the surface that sink inward.

  • Q:

    Why do sunspots occur?

    A:

    The effects of the sun's internal magnetic fields entering and re-entering the surface of the sun result in sunspots. They typically occur in pairs with magnetic fields pointing in opposite directions.
