@Envite: Could you please remove your earlier comment about the answer being plain wrong (before the edit). It seems that people are downvoting due to that. Thanks.

I hope you don't mind that I've edited in a reference. I had no idea who Mike Brown is and it is hard to Google for as there is a current news item about an unrelated man with the same name.

comment Stable polar solar orbit with the Earth continuously observable
@Neomada: Noordung's edit makes your question more appealing to snobs like me who are more likely to read a question that is properly formatted than one which isn't. You should be thanking him, not insinuating that his motives were cynical.

comment If the moon wasn't receding from Earth, what would be the impact on the weather and tides?
The energy of the sound of waves crashing comes from the moon. I am going to mention this to my daughters next time we are at the beach with the moon visible. Thank you for this wonderful insight.

comment Why, in the Solar System, all the mass seems to be concentrated at the centre?
@RobJeffries: Thank you for mentioning the situation with Vega. I do believe that a few years ago it was thought that the disk is protoplanetary. I should read more, science progresses!

I mentioned that "Not much matter can form a stable orbit there" and you might notice that 97% of the mass of the solar system is not found there!
