: You can test it yourself near Sunset on a fine day by sitting in an

Round balls are better. Or are these them european footballs?
I'd probably recommend, say, baseballs. Or tennis balls. Or oranges
and/or grapefruits. But whatever. Whatever's handy, I suppose.
In any event, you don't need sunset. Use a darkened room, an
unsheilded lightbulb placed at some location behind you, and balls at
various locations in front of you. Move the lightbulb and the balls
around as needed. Arguably easier than mvoing the earth and/or the sun.
Oh... well, you turn the lightbulb on, of course.
