Gravity and Oxygen in Star Wars: Is it the same on every planet? Are there variances?

I'm left with the question after realizing that in our own solar system, the amounts of gravity found in all 9 of our closest planets (scratch that, 8 because pluto isn't one anymore, supposedly) differ greatly, not to mention gases.  Let's assume that all the planets in SW have the same gravity and air quality, from Hoth to Tatooine, to Bespin, to Endor... How is this even possible?

There are variances. A good example of the gravitational issues is the Empire opting for the AT walker program. Though repulsorlift technology is tried and true, there are still planets with serious variances in their gravitational and magnetic fields which wreak havoc. Walking around in a gyroscopically stabilized tank is better then bottoming out or being flung several meters into the air due to some anomaly. On Coruscant alone, the difference in gravity between the Senate Chambers, and the outlying auxiliary maintenance shafts can be as much as 20%.
