Astronomy Quick Facts – Arche

Arche is a very small moon of Jupiter’s, and is a member of the Carme group. It’s also known as Jupiter XLIII. It was discovered by a team of astronomers led by Scott S. Sheppard at the University of Hawaii in 2002. Very little is known about it.

Name Origin

Arche was the fourth of the muses of origin. She was one of the five Boeotian muses. She is one of the daughters of Zeus and Mnemosyne.

5 Interesting Facts

1. Arche is a member of the Carme group, which orbits retrograde and at a highly inclined and eccentric orbit. Probably a captured asteroid.

2. Its original temporary designation was S/2002 J 1.

3. It’s pronounced ar-kee.

4. Sheppard has been involved in the discovery of 75 moons.

5. There’s very little known about Arche. I can’t do five interesting facts.

With such a highly inclined and eccentric orbit, and such a small size, it’s unlikely we’ll see any kind of exploration of this moon any time soon.

Political Debates – Some Kind of Bizarre Reality Show

In both the US and Canada, there were a couple of political debates that could help decide the fate of a few politicians.

In Canada, we had the first political debate consisting of four of the five main political leaders (Bloc Quebecois seemed to be absent, not that they’re popular anymore). I didn’t watch it, but I had the impression that Trudeau liked to tell Harper that he was always wrong. The Conservative Party’s falling behind the NDP. Bye bye, Stephen. It seems that Mulcair has become the focus of several memes, using his humourous expressions caught on camera. And May was the apparent winner from what many people have said. Not that the Green Party will win any election. At the end, all of the leaders declared themselves the winner. Huh?

In the US, we had the Republican debate to help determine the Presidential candidate for the Republican Party. Now this was definitely a reality TV show. Again, I didn’t watch it. But it sounds like Donald Trump was being The Donald, as usual. In other words, insulting, misogynistic, and just an all around idiot. He’s out of touch with reality. He’s out of touch with everything. If he becomes the Republican Presidential candidate and wins the election and beats whoever beats Hillary Clinton (if she loses), then the United States has become a circus. No, it should become another reality show. Why not just slice the US up into little pieces, because there’d probably be civil war? It’s not just Trump, it seems the entire group of Republic candidates is full of religious fundamentalists who have no better things to do than try to tell people how they’re supposed to live, tell scientists they’re incorrect about evolution and climate change, and basically want the US to regress back to the time of the ice age. The Republicans are a train wreck. Next year’s election will be interesting, that’s for sure.

Canada’s election later this year is important. It actually seems sane, and is quite likely to completely change the face of politics in the federal government. The American election just seems like the audition part of the X-Factor, America’s Got Talent, or American Idol filled with rejects.

Are you looking forward to the elections?
