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 the Rowley Mile to the adjoining July course. Ridden by Wragg, she won by three lengths from Blue Smoke, with Mrs Feather a further two lengths back in third. Sun Stream's success gave Lord Derby a seventh win in the race as both owner and breeder, and was very popular with the unusually large crowd. A month later, Sun Stream returned to the July course on 8 June for the Oaks Stakes.
