# If earth were the size of a marble would it be smoother than a marble? [closed]

As the title states, If earth were the size of a marble would it be smoother than a marble?

• I'm voting to close this question as off-topic because it isn't about Astronomy. It stems from a humorous meme - may be acceptable on Skeptics if it had a notable claim. – Rory Alsop Aug 14 '15 at 10:57
• darn it sorry, I didnt realise I was in the wrong fourm – AnonDCX Aug 14 '15 at 10:59
• Skeptics does accept things like this but you need to demonstrate a notable claim (have a read of their scope page for guidance) – Rory Alsop Aug 14 '15 at 11:03
• @RoryAlsop I wouldn't call this off-topic. I had a similar question in an undergraduate astronomy problem class. It's a useful question to make the huge scales of the solar system easier to picture. – FJC Aug 14 '15 at 15:38
• Earth radius is 6600km. The Mount Everest is 8848m high. The Mariana Trench is 11km deep. They sum to $\approx$ 20km. Scaling it down by 100km -> 1cm, we get a ball with 1.2m diameter, with at most 2mm roughness. It would not be visible with free eye. – peterh - Reinstate Monica Aug 14 '19 at 0:37
