OK so lets take this step by step...
1. Those are not oceans, but patches of dark ground where concentration of metals is very high. If they were oceans this would be classified earth-like or Water world. Anyone who has done some exploration knows that... So your major point is invalid.
2. and 3. are details. Mainly 3 is a minute difference.
4 I've got to give you this... No moons.
5. Another microscopic difference... I have discovered earth-likes that were over 9k km in radius and under 3km radius. 104.5km difference just doesn't cut it.
Bottom line this is the closest planet to tatooine from elite i managed to find. And if one day there is an opportunity for players to name systems and planets, guess what i am naming this system
... this is my confused face:
My points were in no particular order btw.
1. Ok, I'll admit I may have that wrong,
2. This is a very big detail; unless some catastrophic event occurred to knock it's orbital period out by 638.5 days, this is not Tatooine. Something would have had to knock the planet seriously out of alignment to hit that kind of orbit, and the planet would have either been distroyed or taken millions of years to reform (if that's at all possible), either way this would then have a major impact on the atmosphere (water would have likely been flash-boiled),
3. Minute, but present .. 23 <> 1.2.
5. My point here is that this planet is smaller than Tatooine and therefore cannot be Tatooine.
A major event would have had to occur for this to be Tatooine.
Side note: No breathable atmosphere, concentration of N2 is too high, O2 too low.

Side-side-note: Wait, are you saying this is Tatooine-like or IS Tatooine?
