Excuse the additions that I made to your table. I was a planetary geologist for 14 years and during that time I wrote ~100 papers (and part of a textbook) about the planets. Even though I have not done that work for 20 years, I still have reflexes that make me use km for planet or moon diameter, and usually AU - but sometimes km - for orbit radius. I extended your table to the other planets for completness. I omitted Pluto because the latest research suggests that Pluto is an asteroid rather than a planet. I used the latest values for mean radius and diameter. I replaced "million miles" by "*10**6 mi" to conform with scientific style.
