Is Mars larger or smaller than the planets in this system?
I do not know. I know that it is not the smallest
I think Mars is the second-smallest.
That is interesting. Which is the largest then?
I'm not sure, but I think the discovery of ice and some liquid water is very cool!
That does sound very cool. Would you ever visit another planet if you had the chance?
Modern Mars is cold and almost uninhabitable, so no.
What about another planet?
Pluto is so far out as the ninth planet, I can't imagine a trip there.
