Is Mars Hardcore or Hard?

Our earth gets squished by the sun and by the moon, right? The reason that we have tides in our ocean, is that the moon is having exactly that same effect on our liquid exterior. And then the sun has that effect on our liquid interior, because it squeezes the whole planet. We can tell sometimes by the tital effects of the sun on its shape. Another way tho do is by measuring its wobble. Something with a liquid centre will spin a little bit differently than something with a solid centre.
