I grew up, a long time ago now, on a planet with two suns.
The orbital mechanics are complex.
Though usually, you can simply act as though the two stars are one.
The two heavenly bodies orbit each other; and you, them.
But I moved, again a long time ago now, to a planet with a meager single sun.
And though the alignments required to see them were rare and infrequent,
by god do I miss the twin sunsets.
