It’s called a “sun.”
Don’t look directly at it, or it could permanently damage your eyes. Don’t worry, it’s not going to strike the Earth. It’s 93 million miles away, and not on a collision course with our planet.
It provides light and heat to the eight planets (and Pluto) that are part of the solar system.
I just thought local readers might welcome the reminder after more than a week of dense fog shrouded the metropolitan area.
