The article says "Tycho Brahe is a crater on Mars named after its discoverer, the Danish astronomer Tycho Brahe." I have heard that Tycho was an exceptional observer, but to have managed to observe a crater on Mars without a telescope, which was not invented until after Tycho's death, is beyond extraordinary. 188.8.131.52 (talk) 04:22, 6 July 2008 (UTC)
Why is this article marked as top importance? What makes it so special? --Oefe (talk) 15:41, 27 April 2010 (UTC)
I think this was rated top-importance for WikiProject Mars, not for the solar system project. This is a major feature of the martian surface, so this may qualify. However, I think "high" importance may be more realistic. --ChrisRuvolo (t) 18:28, 27 April 2010 (UTC)
I don't think that being a "major feature of the martian surface" qualifies it as top importance. (BTW, does a crater which is only slightly above 100 km diameter already count as "major feature"?). Many craters on mars are larger than Tycho Brahe, but most of them are marked as low importance, or don't even have an article at all. Those craters that are marked mid or high importance have outstanding features (e.g traces of water) or are research targets (e.g. landing sites). There are only two other mars craters marked top importance, namely Victoria (crater) and Erebus (crater), both of which have been visited and extensively researched by the Opportunity rover. As far as I know, there is nothing which makes Tycho Brahe special, so I think "low importance" would be more appropriate. --Oefe (talk) 14:30, 1 May 2010 (UTC)
