I typed 88 days for Mercury but didn't come up!?!?!?!
A galactic year needs to be an acceptable answer for the name of the sun's revolution around the galactic center. The term is far more common than 'Cosmic Year.' I have no idea how you wound up making the less common usage the ONLY acceptable one.
And magnetar should be acceptable for the magnetic question. I know that 'magnetar' is right in the name, BUT that is the most common name for the very specific type of neutron star that results in the magnetic thing in the universe - magnets so strong that they would rip the very fabric of reality apart and destroy our entire planet if were were too close.
