Weekend Beakful of Knowledge

Most planets don't experience total solar eclipses with the pretty corona shots (like this one). Those are only possible because the moon and the sun appear to be approximately the same size in the sky. The moons of Mars are too small to produce total eclipses on the planet

Also, it helps to have a moon. Mercury and Venus do not experience solar eclipses because they have no moons to get between them and the sun.
