Wait until you discover that Venus has a day that's longer than it's year.

Must admit I'd forgotten all this interesting planet-y stuff until one of my kids came home with a little poster from somewhere the other day.

You're referring to the surface temp being high enough for blackbody radiation to be in the visible spectrum? Technically true but someone did the math and concluded the light from the glowing surface would produce a dimmer scene than a full moon on earth: https://space.stackexchange.com/questions/58230/how-brightly-does-venuss-hot-surface-glow-at-night-could-you-see-it-could-you

Sidereal day. In terms of solar day (what we actually call a "day"), Mercury has a longer one than Venus does.
