Solar phenomena move about and can travel at a few hundred meters per second when they first appear. The solar wind is a stream of plasma released from the Sun's upper atmosphere. It consists of mostly electrons and protons with energies usually between 1.5 and 10 keV. The stream of particles varies in density, temperature and speed over time and over solar longitude. These particles can escape the Sun's gravity because of their high energy. The solar wind is divided into the slow solar wind and the fast solar wind. The slow solar wind has a velocity of about , a temperature
Why Does the Sun Shine? (The Sun Is a Mass of Incandescent Gas) Zaret from Tom Glazer's 1959 album, "Space Songs". The lyrics for the refrain appear verbatim in the 1951 Golden Guide "Stars".

The second track, "Jessica", was originally recorded by The Allman
