What are the realistic problems of a planet orbiting too close to its sun?

Assume we have a planet similar to earth in size and materials. But we put it in orbit of a mass much greater then our sun so that the year becomes much shorter like 10 days (or put it much closer to get the same result on constant mass ignoring other issues).

Now since the earth remains the same but forces increase so does the force difference on earth surface depending on being a daytime or nighttime. Basically objects on surface will be heavier on night side then on day side due to being closer to sun (though I would expect other forces next to gravity to take effect here).

So I read that this effect is relatively small on earth. But increasing the gravitational acceleration of the sun might increase it significantly. At that point my question is how would this affect the planet? Would we be looking at something like having constant earthquakes basically having small wave of earth itself circling the surface? What about atmosphere pressure changes and winds? Are these types of issues plausible or would the planet have to be so much closer (relatively) that other issues would be way more troubling?
