1 00:00:01,680 --> 00:00:18,930 do 2 00:00:18,930 --> 00:00:21,560 the martian opposition of 2014 3 00:00:21,560 --> 00:00:26,509 welcome stargazers I'm James all very director the key cassava pop planetarium 4 00:00:26,509 --> 00:00:27,579 in Gainesville Florida 5 00:00:27,579 --> 00:00:30,869 and then Miley Hidalgo thanks teacher from Miami Florida 6 00:00:30,869 --> 00:00:34,260 and I'm demery guess astronomer from the Cincinnati Observatory 7 00:00:34,260 --> 00:00:37,550 we get to celebrate something really special next week 8 00:00:37,550 --> 00:00:40,930 that's right team the red planet Mars will be a opposition 9 00:00:40,930 --> 00:00:44,019 and when Mars is that opposition its closest to us 10 00:00:44,019 --> 00:00:48,370 and at its biggest and brightest when objects are closer in brighter 11 00:00:48,370 --> 00:00:52,850 this makes a much better for viewing so let's talk about the upcoming opposition 12 00:00:52,850 --> 00:00:53,489 at mars 13 00:00:53,489 --> 00:00:57,040 and why some oppositions are better than others let's show you 14 00:00:57,040 --> 00:01:01,100 Mars is fascinated astronomers for centuries 15 00:01:01,100 --> 00:01:05,729 even the sky watchers on the antiquity were mesmerized by the peculiar movement 16 00:01:05,729 --> 00:01:06,500 brightness 17 00:01:06,500 --> 00:01:10,340 and color changes of mars every twenty six months or so 18 00:01:10,340 --> 00:01:14,170 mars goes from a pale orange yellow to a bright or just read 19 00:01:14,170 --> 00:01:18,210 mars got its name because it's Brett Cullen reminded the ancient Romans a 20 00:01:18,210 --> 00:01:22,530 blood war and violence so they named after their got a poor 21 00:01:22,530 --> 00:01:25,820 the ancient Greeks gave the Red Planet the name pair ease 22 00:01:25,820 --> 00:01:29,450 the name the Greek god of war: and the Babylonians name that never call 23 00:01:29,450 --> 00:01:32,479 after their gotta pestilence and death so 24 00:01:32,479 --> 00:01:35,850 every twenty six months the break you know mars reminded people love the 25 00:01:35,850 --> 00:01:38,500 celestial connection with their God of War 26 00:01:38,500 --> 00:01:43,560 and they came to expect the unleashing a war revolutions disaster and debt 27 00:01:43,560 --> 00:01:47,740 even the symbol for Mars is the stylized Roman sword and shield 28 00:01:47,740 --> 00:01:51,070 but what if Mars change color size and brightness 29 00:01:51,070 --> 00:01:53,490 every twenty six months 30 00:01:53,490 --> 00:01:56,090 if we view our solar system from high above the Sun 31 00:01:56,090 --> 00:02:01,340 we can see the orbit support earth and Mars it takes a little more than 365 32 00:02:01,340 --> 00:02:02,500 days to orbit the Sun 33 00:02:02,500 --> 00:02:06,840 while Mars takes almost 687 days when my sister 34 00:02:06,840 --> 00:02:10,389 alright their closest to each other Mars's at to be at opposition 35 00:02:10,389 --> 00:02:13,440 when a plan is that opposition it's exactly on the 36 00:02:13,440 --> 00:02:17,500 opposite side at the sky from the Sun the tricky part about martian 37 00:02:17,500 --> 00:02:18,400 oppositions 38 00:02:18,400 --> 00:02:22,579 is that sometimes Mars is much closer at some oppositions then 39 00:02:22,579 --> 00:02:27,150 others for example the martian oppositional August 2003 was one of the 40 00:02:27,150 --> 00:02:28,190 closest ones 41 00:02:28,190 --> 00:02:33,060 ever work Earth and Mars were only 30 4.6 million miles apart 42 00:02:33,060 --> 00:02:36,510 compare that to the opposition March 43 00:02:36,510 --> 00:02:40,290 when Mars is a whopping 62.6 million miles from Earth 44 00:02:40,290 --> 00:02:44,910 the reason the mars is distance very so much is because in the shape of Mars is 45 00:02:44,910 --> 00:02:45,500 art 46 00:02:45,500 --> 00:02:49,980 Johannes Kepler demonstrated that planetary orbits are not perfect circles 47 00:02:49,980 --> 00:02:54,180 but a shape called inlets Mars orbit is more logical than Earth's 48 00:02:54,180 --> 00:02:57,760 so there are times when Mars is much closer to the Sun than others 49 00:02:57,760 --> 00:03:01,510 when a planet is at its closest to the Sun 50 00:03:01,510 --> 00:03:06,150 we call that Perry Helion the perihelion point for Mars lies in the constellation 51 00:03:06,150 --> 00:03:07,090 Aquarius 52 00:03:07,090 --> 00:03:10,820 the point when a plan is far this from the Sun is called at helium 53 00:03:10,820 --> 00:03:15,910 and from mars that point is in Leo the Lion perihelion actually in our 54 00:03:15,910 --> 00:03:19,100 opposite sides in the planet's orbit and as a result or on 55 00:03:19,100 --> 00:03:22,670 opposite sides the sky cell if you look at the zodiac 56 00:03:22,670 --> 00:03:26,260 what constellation is on the opposite side of the sky from Leo the Lion 57 00:03:26,260 --> 00:03:30,470 to its Aquarius cell if the Sun is a Leo 58 00:03:30,470 --> 00:03:33,880 and Mars in Aquarius you get a close and bright opposition 59 00:03:33,880 --> 00:03:37,120 but switch around and if the Sun is an Aquarius 60 00:03:37,120 --> 00:03:41,260 and Mars in Leo you get a distant and think opposition during the martian 61 00:03:41,260 --> 00:03:41,930 opposition 62 00:03:41,930 --> 00:03:44,970 1956 Mars was extremely close and bright 63 00:03:44,970 --> 00:03:49,280 this happened in September when the Sun was unreal and Marshalls an Aquarius 64 00:03:49,280 --> 00:03:53,570 the opposition 1877 when fogelson day most were discovered 65 00:03:53,570 --> 00:03:57,000 also happened in September and again marshals in aquaria 66 00:03:57,000 --> 00:04:00,959 on the other hand the martian opposition ups 1997 67 00:04:00,959 --> 00:04:04,950 wasn't very impressive happen in March when the Sun was an Aquarius 68 00:04:04,950 --> 00:04:08,580 and Mars in Leo same thing happen in March 2012 69 00:04:08,580 --> 00:04:11,769 things are getting better though next week on April 8 70 00:04:11,769 --> 00:04:15,540 Mars will be in Virgo and the Sun will be in Pisces they're both one 71 00:04:15,540 --> 00:04:17,039 consolation over so 72 00:04:17,039 --> 00:04:21,209 it's not quite as bad each time we go around the opposition's will get better 73 00:04:21,209 --> 00:04:21,950 and better 74 00:04:21,950 --> 00:04:25,360 then in late July 2018 will get the best view 75 00:04:25,360 --> 00:04:30,760 mars we've had since 2003 so check out march right after sunset next week as 76 00:04:30,760 --> 00:04:31,229 you 77 00:04:31,229 --> 00:04:52,050 keep looking up 78 00:04:52,050 --> 00:04:56,850 yes me 79 00:04:56,850 --> 00:05:01,850 T
