Wind as the Earth to evolve into planets like Venus. Additionally, planets with hotter lower atmospheres could accelerate the loss rate of hydrogen. Rather than air, the solar wind is a stream of charged particles—a plasma—ejected from the upper atmosphere of the sun at a rate of . It consists mostly of electrons and protons with energies of about 1 keV. The stream of particles varies in temperature and speed with the passage of time. These particles are able to escape the sun's gravity, in part because of the high temperature of the corona, but also because of high kinetic energy
Sun Stream Stakes and became a successful broodmare, producing the 1000 Guineas winner Tideway and Heliopolis, a full brother to Sun Stream who was twice Leading sire in North America. Lord Derby sent the filly to his private trainer Walter Earl at his Stanley House stable in Newmarket, Suffolk.
