Hi, I teach my boys at home and the question of a light year came up. It says in our book that it takes 8 light minutes for sunlight to reach the earth. So, do 60 light minutes equal a light hour? Are there then 365 light days in a light year?
Also, my son said he saw on the discovery channel that it takes "millions of years" for the light from the core of the sun to reach its surface. Is this true? It then takes 8 light minutes from there? I've tried to research this on the web, but haven't found any answers.
Also, what is the difference between a solar flare and solar prominence? Do solar flares just burn hotter and quicker?
Thank you so much for your answers!
