Shame on Brown and his little balls. (I won’t go into a full lecture on said physics), You say Earth has more in common with Pluto than Jupiter? However, experience and technology developed during ERIS was put to use in the current missile defense programs, like THAAD (Theater High-Altitude Area Defense) and the GBI (Ground-Based Interceptor) missile of the GMD (Ground-Based Midcourse Defense) system (formerly NMD; National Missile Defense). I have no data about the exact physical characteristics of the ERIS test vehicles. And More…, Episode 678: Q&A 126: When Did Mars' Dynamo Shut Off? I knocked it down from 800 down to 230 so I wasn't too painful. Additionally, the matter of what is a planet was NOT settled by the IAU in the summer of 2006. There was a skit called “one of these things doesn’t belong”. Two other objects in the asteroid belt, Vesta and Pallas, are not quite spherical but are much more larger and more complex than the rest of the asteroids. You can verify this with Bruno Sicardy or Alan Stern. It matters because planetary scientists want to see objects classified as accurately as possible. Flight test vehicle for Exoatmospheric Re-Entry Interceptor Subsystem, an anti-ballistic missile hit-to-kill interceptor warhead. Want to be part of the questions show? The team had been saving this name, which was inspired by the title character of the television series Xena: Warrior Princess, for the first body they discovered that was larger than Pluto. “… after its discovery put it’s…”, I missed you Ivan, so that dwarf apostrophe was a gift for you. What difference does it make which one is bigger? 06:21 It's probably not life. Now that we do know these things, it is clear that the demotion of Ceres was an error, as was the demotion of Vesta and Pallas. No, the question of what is a planet is NOT a settled definitional issue, which is why both sides of the ongoing debate should be presented. Our sun is a dwarf star and yet a star. Why are scientist scared of having more than 10 planets in the solar system? You remind me of those Metric Martyrs in the U.K. who stubbornly refuse to conform to the more logical metric system. I gather a bunch up each week and answer them here. We certainly should discuss planet formation, but it’s not an either/or. It is perceived as an anti-Pluto definition for good reasons. So why should Mercury be considered a planet? Eris, which has the full title of 136199 Eris, was first observed in 2003 during a Palomar Observatory survey of the outer solar system by a team led by Mike Brown, a professor of planetary astronomy at the California Institute of Technology. Seems logical. More stories at https://www.universetoday.com/ I hope when the planet Eris closer to Earth, there would be a robotic mission to the Planet Eris.. The petition by 300 professional astronomers opposing the IAU decision is just as valid a statement as is the initial vote. On the first intercept attempt on 28 January 1991, the target RV deployed two balloon "decoys" on each side, but the KKV was preprogrammed to home on the center target (i.e. So let’s look at the Solar System, shall we? The actual size and mass of Eris has been the subject of debate, as official estimates have changed with time and subsequent viewing. Science does not work by decree from “on high.” Decrees and dogmas everyone has to accept are typical of a church, not of scientific bodies. If we used the same logic on those systems, none of these objects could be considered planets. But back then, no one knew that our solar system has many dwarf planets, not just Pluto. It also takes an eternity to scroll through everything since there's no buttons to skip through it by letter. Either way, this is all semantic based rhetoric and however they go is the way it should be. Why someone who inanely claims to have killed Pluto is repeatedly given a soapbox to defame Pluto is beyond me, especially now that Bruno Sicardy’s data suggests that Pluto is larger than Eris.
